Subject Performance decrease of ODMG-api in CVS
Date Fri, 03 Oct 2003 22:38:20 GMT

Hi all,

some user reported about a ODMG-api performance
decrease of current CVS. I think they are right.
The performance test (perf-test task) for odmg-api
took 43 sec with rc4 (27 July)
took 37 sec with new DList implementation (1 August)
took 55 sec (ca. 25 Sep)
took 48 sec after fixing lock cleanup (today)

So performance of odmg-api decrease more than
30% between 08/01 and 09/25!
I couldn't find out the reason for that. Seems that
the changes made in odmg classes between this
period are minor. Maybe the reason are changes in
the kernel. But the kernel only performs ca. 5%
Any comments, proposals, solutions?
