PJM (8/22/2001 4:14:57 PM) David Whiteman did a few tests timing image related stuff between JDK AWT, our AWT, and SWT. NOTES: PJM (8/22/2001 4:17:48 PM) Andrew Sandstrom did some looking at AOT'ing and JIT'ing bits and pieces. Here are the relevant notes: Using a pretty vanilla Smartlinker feedback directed optimization loop I can get about the same performance (1.8-1.9 sec) and ony 53K bigger. Here is what you can do. Run the app once with the following option: -Xrunslprof:fn=D:\SmartlinkerProfiling\out,of=xml,pm=cpu,sp=1,st=true Then add the following options to your jxeLinkOptions file: -cp D:\SmartlinkerProfiling\ -feedbackProfile out -precompileByGain 100 You can replace "D:\SmartlinkerProfiling" with any directory I tried different scenarios with running multiple times, profiling calls and adding -inlineHotCallSites, etc, but I didn't get much benefit beyond the simple straightforward approach. -Andrew MVM - (28/08/01 9:28:04 AM) We all know that AOT and JITing only helps on Win and AIX. I would like to see the C version personally, especially as SWT for Palm now uses some image loading etc.. and will not benefit from this, and is currently extremely slow due to this.
PRODUCT VERSION: SWT 2.002 Windows on NT 4.0
We have fixed numerous image performance issues over the years. I'm going to assume this has been fixed.
