Quickie Q: Should I expect to see performance improvements with SMP and a multithreaded app using libc_r? The app in question is MySQL and doing the sql benchmarks with an SMP (dual pII 350) and non-smp kernel for the same box, I see much faster times with the non-smp version. system is: FreeBSD 3.1-RELEASE #0: Mon Feb 22 00:41:53 GMT 1999 root@geek.circle.net:/u sr/src/sys/compile/DOU-MU-2-NO_SMP I find it strange, but in the smp version the mysql daemon process seems to spend an awful lot of time in STATE "getblk". I'd appreciate pointers or tuning suggestions to make this work better. -Troy Cobb Circle Net, Inc. http://www.circle.net To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
