It's generally a good idea to subscribe to the DRI and Mesa mailing
lists if experiencing GL performance issues or other problems.  The IRC
channel #dri-devel on freenode.net is also quite useful.  That's a
direct pipe to the developers, who are generally quite helpful and
often provide troubleshooting tips, etc.

Hope this helps.
