[Opensim-dev] ODE on Linux x86/64

[Ursula MATOVA]

Hi Jeroen,

1/ I didn't experienced any slowdown at the moment, but the server is 
really too powerfull to notice that ...
( Xeon 2.66GHz Quad Core, 8GB Ram, 25 Regions in Grid mode, MySQL 
storage, OpenSim SVN 7311 )
BUT : Note i'm using the very latest Mono ( not 1.9.1 ).

I'll try to do some tests this week end on the core2 Duo with Ubuntu 
64bits and let you know the results.

2/ Adam, do you mean that only BulletX should be used un x86/64bits ? 
Why not ODE ? It's a very nice engine, working perfectly for common use ...

Regards,
Ursula.
