Host C may only be UDMA33, and possibly have a slow drive, with a > lower amount of memory for caching. Did you rebuild kernels on any of them? > so many questions :-)! the test were run many times, on host C the port was changed, the cable was changed, the NIC was changed. the disk is not relevant, the test uses a small program i wrote that writes from memory. at the moment all three run the same version of the kernel, the only diff is that A & B are smp, and C is not. danny To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
