[jira] Created: (HARMONY-1993) A stress test for young generational
allocation that measures allocation rate
A stress test for young generational allocation that measures allocation rate
-----------------------------------------------------------------------------
Key: HARMONY-1993
URL: http://issues.apache.org/jira/browse/HARMONY-1993
Project: Harmony
Issue Type: Improvement
Components: DRLVM
Reporter: Rana Dasgupta
Priority: Minor
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

[jira] Commented: (HARMONY-1993) A stress test for young

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.

Yes. The test is a Java test. The reason I placed it in gc_gen is that it is
intended to stress allocation fastpath and corresponding gen 0 collection,
and is more useful for tuning these.

first, can we also use this test for gcv4.1?
Second, shouldn't you test now to make sure that all is well? It will
be much harder to figure out later...
