I've been asked to make some hardware recommendations, I'm hoping some folks on the list can make some suggestions.
We're looking hard at getting either Intel dual-core procs, or getting hyperthreaded procs with huge (8M) caches. We currently have a few dual proc Intel HT machines that we can test out our workload on, and I'm trying to get a feel for how to determine if a larger cache size will generate better performance than replacing HT procs with full-blown dual-core procs. We're looking at the 6850 from Dell, which supports both processor families: http://www1.us.dell.com/content/products/productdetails.aspx/pedge_6850?c=us&cs=555&l=en&s=biz The goal for these machines is to serve out PosgreSQL databases to as many Apache+php front ends as we can hang off each one. So we're trying to purchase hardware that will create a DB server that can handle a lot of web server front ends. I have a Dell 2850 (dual HT procs) here that I can use for testing. I'm a little fuzzy on determining how well the cache is working, so I'm stuck on whether or not the 8M cache that's available on the HT units is worth the money or not. Can anyone suggest a testing methodology that will isolate this particular aspect? -- Bill Moran Collaborative Fusion Inc. _______________________________________________ email@example.com mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
