Spec will be: Dual 244, 2Gb RAM, 5x400Gb SATA RAID 5 on a Highpoint 1820a Broadcom 5705, Intel gE and a Intel dual port ( PCI 32 ) for comparison. Will let you know the results.

The 3ware card and the Dual Port em are both in the PCI-X 100 slots (the first two). There are no 32bit cards in the machine. Is there some method I can use to determine if the PCI bus is the bottleneck or even to determine the level of contention on the bus? I've been looking at the newer Opteron boards with multiple PCI buses but that's a lot of money to spend on my hunch. -- Sean _______________________________________________ freebsd-performance@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-performance To unsubscribe, send any mail to "freebsd-performance-unsubscribe@freebsd.org" ================================================ This e.mail is private and confidential between Multiplay (UK) Ltd. and the person or entity to whom it is addressed.
