Status: Verified
SYMPTOM(s):
Performance degradation on Xeon machine with Workgroup database license
More CPU's are involved, worse performance goes
Performance is much better with only 1 CPU active
Application uses correct indexes
Using Enterprise database with -spin enabled is not the option
strace shows client spends 50% of its time in semop() function
Machine's CPU's are not utilized at all (CPU usage is zero)
Performance is better with Hyperthreading disabled, but still not same when only 1 CPU is active
FACT(s) (Environment):
Progress 8.X
Progress 9.X
OpenEdge 10.0X
Linux Intel
Windows NT 32 Intel/Windows 2000
CAUSE:
Bug# OE00111981
FIX:
Upgrade to 10.1B02 or higher.
If that is not possible at this time try the following work around:
