Subject [jira] Commented: (HARMONY-1993) A stress test for young generational allocation that measures allocation rate
Date Tue, 31 Oct 2006 16:54:47 GMT
    [ http://issues.apache.org/jira/browse/HARMONY-1993?page=comments#action_12445950 ] 
Rana Dasgupta commented on HARMONY-1993:

My request would be that we commit this. This is turning out to be quite a useful and focussed
little benchmark to study young object handling and even some code jitting. The dev list seems
OK about its location in the gc_gen directory.

>             Project: Harmony

>            Priority: Minor
>         Attachments: gc_genbuild, gentest
> These two patches are for adding a stress like test to gc_gen that creates and discards
a large number of young objects repeatedly on an increasing number of threads. The test focuses
on gen0 and allocation rate. The gentest patch needs to be applied to the gc_gen directory
> The gc_genbuild are the build modifications to gc_gen
> We may want to hold off committing till the list agress on where these focussed component
tests that run for a while and don't return a pass/fail should live.
> Tested on 32 bit Linux ( RHEL ) and XP
