Configuration: Eclipse 2.0.1 RedHat 8.0 JDK 1.4.1 Some operations, like first opening the properties dialog or changing within dialog are extremely slow. They can take up to 2 minutes! After the first time, everything works quite fast again. Other operations take even longer. Generally it's the processing in dialog windows, for example in new project.
Further notes: CPU is Pentium II 450MHz Also this is not exactly quick, I can work adequately with Eclipse. I can also accept that it is a little slow at the beginning, but these delays are unusual. I made an strace and an ltrace while running eclipse. strace simply doesn't show anything during these stops, and ltrace shows a lot of malloc's and free's and nothing else (so no file operations too). I increased the memory size for JVM, to no avail. I also made the JVM spit out some information using -verbose and -verbose:gc. During these long halts, they don't show anything at all.
This is due to plugin activation when Eclipse is first invoked - a Properies page in particular will invoke numerous plugins that can take some time (like the JDT plugins). Do you have another example of an operation that is very slow?
Also how much memory do you have on your machine?
I have 256M. Also, if there was plugin activation, should there not be output due to the -verbose flag? i.e. class loading garbage collection. During the stall there is no GC. I use Eclipse 2.0 for a while, and this probably has only recently occurred. I don't know what could have triggered it.
Have you seen any improvement with M3? A few perfomance issues were addressed in that release. The more specific you can be with respect to what operations are slow the faster we can concentrate on improving that area.
I have installed Eclipse M3 on my new computer (P4 2.4 GHz, 512MB), and the Preferences dialog still takes some 10 seconds to popup. I started Eclipse several times, so that in the end, almost no disk access is made, so it can't be the problem of a slow HD.
motif or gtk? Which window manager are you using? How large is your log file in .metadata? Just trying to reproduce the scenario. I run a PIII, 500 with gtk and motif on RH7.2, KDE, IBM JDK1.3. I don't see the delays you report.
The .log file was some 1.3 MB, I deleted, but no noticeable change. Its the GTK version on RedHat 8.0 with Sawfish Window Manager and JDK 1.4.1. In fact I use the same configuration on my machine at work, but that is a Pentium IV/2.2GHz with 1GB RAM, and there the delay is much shorter. I don't know what the difference might be. I also tried a fresh installation of Eclipse with a different workspace - to no avail.
Still have not been able to reproduce this problem. When I open the preferences dialog for the first time I can count "one one thousand, two one thousand" and it complete prior to my last "thousand", definately less than 10 seconds and I have a 500Mhz machine. I have 21 projects open in my workspace. I am assuming you are still using the same configuration: P4 2.4 GHz, 512MB 256 Meg RH 8.0 JDK 1.4.1 (IBM or SUN?) What command line arguements are you using to start eclipse? How many editors are open in your workspace How many projects are open in your workspace Are you running locally or over a server? On windows programs such as Norton anti-virus effect the performance of eclipse, are you running similar types of software in the background? I am assuming you have ran other programs on this same computer with no performance issues.
On both machines I start eclipse without any commandline arguments. In fact I tried various arguments on the slow eclipse installation, for example -vmargs -Xms150m -Xmx180m, but no change. The JDK 1.4.1 is from Sun on both machines. The same projects etc... I can't figure what the difference may be. What other information should I give. Would an strace help?
We have not been able to reproduce this behaviour on our machines. Are you still having trouble on that one machine? The R2.1 M5 candidate load is looking fairly good on GTK. Can we either close this bug or lower it's priority?
Just now I experienced the problem again. I started Eclipse on my 2.2GHz machine running JDK 1.4.1. I clicked on a file in the Package Explorer. It took around 20 seconds for the editor to show up. There is also another problem, that occurs sometimes. Menus and scrollbars stay responsive, but nothing happens. For example I can move the scrollbar in the editor, but the text does not scroll. After a long while everything works again, but sometimes it doesn't work again and I have to restart Eclipse. Also sometimes I type in the editor window and suddenly input doesn't show up anymore until after a delay of perhaps 15 to 20 seconds. I have not found anything unusual in my configuration and happens with both the JDKs from Sun and from IBM.
Investigate for RC1. Gemi, an strace would be helpful. Could you also try: - install M5 build (I20030206-1700) - copy the .options file from plugins/org.eclipse.ui to the directory with the eclipse executable - run with: -debug -vm {java-install-dir}\bin\java.exe (this gives you a console)
This is what I did: 1. Eclipse M5 is in /opt/eclipse 2. I copy plugins/org.eclipse.ui_2.1.0/.options to /opt/eclipse 3. I start using /opt/eclipse/eclipse -debug -vm /opt/jdk1.4.1/bin/java 4. The output is in debug.log, attached. 5. When Eclipse has started up I click on a file in the explorer, it takes some time to open the editor, then I can't scroll the text in the editor, only the scrolbar changes 6. The same, but just before I click on the file to open, I do an strace on the process. The output is in the attached strace.log.gz 7. Incidentally I get SWT error, I attach the error log in log.gz
Sorry, By mistake I attached the files to another bug report of mine, number 28730. Can you retrieve it from there?
Created attachment 3436 [details] debug log file of -ebug
Created attachment 3437 [details] log file of eclipse
Created attachment 3438 [details] strace log file
What were you doing when you generated the strace? It would be ideal if the strace could capture one slow reproducable operation with no other noise from other events.
Could you attach your .gtkrc/.gtkrc-2.0 file? What themes do you have on the machine that is running slow? We have noted that some themes slow down eclipse. In addition if you request a font that is not natively supported then performance is also impacted.
I used to use Bluecurve on RH. But it seems that it doesn't depend on the theme, as it happens with any of them. I just installed RC1. There is no improvement to my problem. Sometimes Eclipse works perfectly alright, but at other times I simply can't do anything. When I move the cursor or edit in the text editor, it hangs a while, than does something, then hangs a while etc...
Have you tried using a different VM?
I tried: - Sun 1.4.1_01-b01 - Blackdown 1.4.1_01-b01 - IBM 1.4.0 IBM build cxia32140-20020917a with the same results.
Installed RC2, it seems to get even worse. There are periods, where everything seems to work alright. But then, for example I do a Rebuild Project, the window pops up with the text "Building project", but then nothing happens. Sometimes also, Eclipse sits there seemingly idle, but I see from the output of top, that the java process consumes pretty much all resources. I really don't know what the problem is. I even did weird things like ipcclean... So when I work with Eclipse, I have to kill it and restart it several times, to get to work a little. I really like Eclipse, but in this state it is difficult to use it. Please tell me what I can do to localize the problem.
Gerard I suspect you are seeing Bug 28343 which will eat up all of your CPU time. Do you run with the CVS Decorator on? If so turn it off an see if this solves your problem. Either way Bug 28343 is fixed in the current integration build - the PR is only open so that it can be verified.
Note that "-vmargs -Xms150m -Xmx180m" must come at the very end of the command line. Placing it in the middle will have no effect. I would recommend "- Xmx256M". What is the result of "rpm -q atk gtk2 glib pango freetype"? What is the result of "echo $LANG"? Do you have any fonts specified in .gtkrc-2.0? Have you changed the default fonts through the Preferences dialog? Is your workspace located on your machine or on a remote server? Do you have any anti-virus software running? Does it run on every file read? Can you copy the Configuration details from the About dialog in Eclipse?
rpm -q atk gtk2 glib pango freetype atk-1.0.3-1 gtk2-2.0.6-8 glib-1.2.10-8 pango-1.1.1-1 freetype-2.1.2-7 LANG=en_US LC_ALL is empty Font ist standard RedHat, font for editor is LucidaSansTypeWriter-12 (bitmap font). I attach the config details. I just installed the motif version in parallel. It seems noticably faster. Can this be true? If yes, I hope the GTK2 version will catch up. I am not keen on using the motif version.
Created attachment 4117 [details] Configuration details
I note from the configuration details that you have not specified -Xmx256M, or any other size. I am going to try running my workspace with the preferences you have set. Command-line arguments: -os linux -ws gtk -arch x86 - data /home/gemi/.eclipse/workspace -install file:/opt/eclipse/
Your glib looks fairly old, we recommend glib 2.0.4-1 but I am not sure this will have any impact on performance.
sorry, that would be rpm -q glib2 glib2-2.0.6-2
Gerard, Can you answer these two questions from comment #26: Is your workspace located on your machine or on a remote server? Do you have any anti-virus software running? Does it run on every file read?
After loading your preferences I noted all the nice colours you have on the tool bar. Have you tried resetting the preferences to their defaults and seeing if there is a performance improvement. This is in align with comment #25, where Tod wanted you to try turning decorations off. You can save your current preferences by Window->Preferences->Export The easiest way to reset your preferences is to start a new workspace. The other way is remove all the preference files from .metadata/.plugins. I would try the new workspace. If you don't notice a difference in performance then you can reimport your old preferences you saved above. Please let me know if you notice any difference. I have noticed differences here on my workstation, although I don't think it is enough to account for the performance issues you have reported.
The workspace is local, the source code of the project is checked out from CVS. There is no anti-virus software on the machine. I will look what I can do regarding to default configuration. Maybe it would be an idea to bundle the required gtk2 libraries with eclipse?
I tried a fresh workspace and created my project anew. However the problem is still the same.
So this is what I did: I grabbed the latest gtk sources and compiled them into a separate location (/opt/gtk): glib-2.2.1, gtk+-2.2.1, pango-1.2.1, atk-1.2.0 then I set the LD_LIBRARY_PATH to /opt/gtk/lib and lo! everything seems to be working nicely! I will have to work a little with it to see if it is really as it seems, but I am full of hope.
Alas, my hope was a little to early. A first start did work, but afterwards it wouldn't get past the splash screen and hang :-(

Removing milestone tag since we still don't understand this problem.
Not sure if I should be posting here, but it gave me an account so.. I have what seems to be the same problem. It mostly manifests when opening a file from the package explorer (this is the main hierarchy view i use), and when selecting a member from the outline view (for a file already open in the editor). I tried deleting my workspace (as it was from a previous build and i thought there might be some sort of conflict), re-importing the project I'm working on, and altering a few settings back to what they had been. This seemed to almost solve the problem, it happened rarely for a few days, but now it's getting more regular. I'm using: Redhat 8 Gnome 2.0 Eclipse 2.1 RC3a sun 1.4.1 jvm Hardware is: 800mhz athlon 384 meg ram lots of free diskspace
Adding Felipe to the list as many GTK performance issues were sorted out by the RedHat 9 implementation. Have you tried the same thing on RedHat 9.0?
Gerard, look Bug#36698. It has instructions about how fix your GTK.
I actually run RH 9 now, and it seems to be better. Thanks.
