[Bug 11387] New: SMP/Dual core performing worse than single core

http://bugs.winehq.org/show_bug.cgi?id=11387

Summary: SMP/Dual core performing worse than single core
           Product: Wine
           Version: 0.9.54.
          Platform: Other
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

I searched for another bug report on this but did not find anything.  I've
tested the same application on two similar systems with similar software loads.
 Essentially, the application (Majesty) preforms considerably better on a
single core system than it does on a more powerful dual core system.

Single Core System:
AMD Athlon(tm) 64 Processor 3300+
1.5 Gig RAM
GeForce 6200 256M

Dual Core System:
AMD Athlon(tm) 64 X2 Dual Core Processor 3800+
2 Gig RAM
GeForce 7800 256M

Both systems are running Debian Etch, with kernel version 2.6.18-5-k7, NVIDIA
GLX Module 100.14.19, and Wine 0.9.53 (using Scott's packages).

I would expect the dual core system to run as well, if not better, than the
single core system.  However, it is extremely sluggish on the dual core system
and blazingly fast (in some cases needing to be slowed down) on the single
core.

I have also tested the dual core system with 0.9.54 (built using Scott's 0.9.53
package as a basis), with no improvement.  I'll happily provide any additional
information that would be helpful.
