Barney,
You should check out this link. [url=“wmusers.com”]wmusers.com .  I’m not sure a whole lot can be done to tune the performance to make up for the difference.  Other than the normal stuff, turning off document logging, using filters correctly etc.
I think there is a big inherent difference between the performance of this particular C process on Linux version Windows.  It doesn’t appear that webMethods spent a lot of time tuning it for Linux.
