[jira] Commented: (DERBY-260) Derby is not stable on multiprocessor or Hyperthreating architectures.
[ http://issues.apache.org/jira/browse/DERBY-260?page=comments#action_64651 ]
Sunitha Kambhampati commented on DERBY-260:
-------------------------------------------
I have run some simple tests on a 1cpu (linux machine) with hyperthreading enabled and once on a 2cpu (Intel Xeon) win2k machine with hyperthreading enabled and it worked fine.
Can you provide more details on what issues you noticed. That would really help to resolve this issue.

It seems that Cloudscape is not functioning on multiprocessor or Hyperthreating architectures. Has anyone some more information?

I also would like to see more information on this. I have been running
the full set of tests on a 2 processor windows 2000 machine for the last
5 years or so. The machine is slow by today's standards (700 mhz
processors), but I don't know of any outstanding database server issues
due to multiprocessor.
