| Re: [jdt-core-dev] The new JDTindex. Should I note a difference as user? |
No. The new index is not intended to speed up indexing time. It will eventually speed up all searches and most operations that read from .class or .jar files. It also makes the index fully readable during indexing which will potentially allow us to make some things that currently block on the indexer become nonblocking.In the current (incomplete) implementation, indexing time is expected to take about twice as long since the old indexer is still active and there are now two indexers competing for resources.On Tue, Oct 11, 2016 at 6:04 PM Igor Fedorenko <igor@xxxxxxxxxxxxxx> wrote:Do you expect the new implementation to be faster when indexing large workspaces (thousands or projects with gigabytes of dependency jars)?--Regards,Igor_______________________________________________On Tue, Oct 11, 2016, at 08:58 PM, Stefan Xenos wrote:You shouldn't notice a difference as a user. If nothing is broken then this version is working correctly. I had to disable the cache changes to get the tests working, and without the cache changes the performance improvements are fairly modest.The index hasn't been adopted in search or open type yet. We've only adopted it in the type hierarchy. You should see a slight performance improvement in the type hierarchy, but we'll need to finish the work on the JavaModelManager cache and do more adoption before we see more widespread improvements.- StefanOn Tue, Oct 11, 2016 at 12:15 PM Lars Vogel <lars.vogel@xxxxxxxxxxx> wrote:Hi,I'm trying to test the new index from Stefan.

I'm not sure how to test the indexcreation, I usually activate and deactive the "Include all plug-insfrom the target platform in Java search" PDE preference.Best regards, Lars--Eclipse Platform UI and e4 project co-leadCEO vogella GmbHHaindaalwisch 17a, 22395 HamburgAmtsgericht Hamburg: HRB 127058Geschäftsführer: Lars Vogel, Jennifer Nerlich de VogelUSt-IdNr.: DE284122352_______________________________________________jdt-core-dev mailing listTo change your delivery options, retrieve your password, or unsubscribe from this list, visit_______________________________________________jdt-core-dev mailing listTo change your delivery options, retrieve your password, or unsubscribe from this list, visit
