There are two things that will give you the vast majority of your speedup - kernel and libc. The kernel is already optimized. I don't know about libc.

Doubtful. Once it is loaded it is loaded.

This is ABSOLUTELY correct. It just isn't worth it, except for a few core things, and specific places where you need it. -- Tim Hockin Systems Software Engineer Sun Microsystems, Cobalt Server Appliances [EMAIL PROTECTED] _______________________________________________ cobalt-developers mailing list [EMAIL PROTECTED] http://list.cobalt.com/mailman/listinfo/cobalt-developers
