    [ https://jira.jboss.org/browse/JBDS-1112?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12557349#action_12557349 ] 

Lukas Jungmann commented on JBDS-1112:
--------------------------------------

yes, as of now I'm able to run startup test from eclipse test framework against JBDS 4 on my box through local hudson(apache) instance. Issue I have at this point is that I cannot reliably run the test at least 20-30x for old/new VM options in a row because of JBDS-1372. I could modify JBDS to not include Teiid modules to get at least partial results but I don't see bigger value in this.

> Eric S. suggests in http://www.schabell.org/2010/02/jboss-developer-studio-performance.html and http://www.schabell.org/2010/02/jboss-developer-studio-300rc1.html that adding the following to eclipse.ini
> -XX:-UseParallelGC 
> -XX:+AggressiveOpts 
> -XX:-UseConcMarkSweepGC
> Makes the startup significantly faster.
> I could not reproduce the results on Java6/Windows 7 combo but it would be interesting to see if it does make a differences on other machines since my machine is broken in other ways.
