Well, it looks like others have even better connectivity that I have available so it is looking like it will truely be a team effort.

Sounds good. Do you have a URL or other subscription info?

THere was mention here on the kernel list in the past few weeks. I don't think I still have the address for the mailing list that was set up but this is also a high priority for us. I have some things written in tcl that I had started working on including a web based "control-panel" where you could watch the performance of various servers. I will crank up development on that again in the next couple of weeks.

Hmm. A howto is a good idea but the problem with them is they tend to go stale quickly. We would need someone to "bird-dog" the thing and make sure that it is kept up to date with different sections for different kernel versions.

Great. There are several others that are also offering resources, two sites with websites, at least one other mailing list. My goal is to somehow tie together all of the resources so that there is a single place to go for all the information. I am also interested in benchmarking things on a set of reference systems. I want to get exact numbers on different hardware, different tweaks and the results on these different hardware configurations, etc. For example, how much of a performance delta is there REALLY between two different SCSI controllers or drives. Does a particular tweak have a larger impact with certain hardware configurations. The goal is to get this documented and keep it up to date as new hardware and software becomes available.
Knowing what to tweak is only half the issue, knowing if it is even going to make a difference worth the effort is also important. Which tweak is going to get you the most performance gain? WHich ones have the potential to cause other problems with certain hardware configurations?
THis information could be a great help for hardware vendors, software vendors and the community as a whole.
