advice on benchmarks for smp/scsi system

what tools are the state of the art benchmarking tools for network, disk and interrupt latency testing?

I need to do some kernel performance characterization on a dual xeon, dual Gb ethernet, SCSI320/RAID system.

I need to measure network throughput vs CPU load, disk throughput, interrupt latency, network to disk streaming and disk to net streaming.

I need to characterize the stock rh7.3 2.4 smp kernel, stock + pre-emption patch, stock + latency patch and stock + both. I also need to test the same basic combinations, but stripped and optimized for my specific hardware. I know in a general way that I will probably find the most joy with stripped/optimized + both, but I need specifics.

I also need to compare compiled in scsi and e-net vs modules

any recommendations for which sets of benchmarking tools to use would be appreciated greatly

Thanks for your time,

Mark
