Kyle, Sorry for late answer, I am afraid I switched back to edgy few days ago, so I cannot test with the new kernel. But I installed feisty kernel(both the generic one and the one I compiled by customizing it) in edgy. The problem does not occur with the same kernel in edgy, cached reads are normal (~1500 MB/S). I don't know if this info will be any useful to lead your work in some direction but just wanted to let you know with that hope. It would be great if the other folks had tried that if they still hold feisty on their workstations. Thanks.
-- read from cache is much slower with feisty than all previous ubuntu versions https://launchpad.net/bugs/90531 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
