I have only tracked Feisty for about two weeks, and my drives performed great with Edgy and 2.6.17. Actually took me a while to notice that certain things were a little slower. One thing is much slower: I have an XFS partition where I keep an Eclipse workspace. Eclipse (running with Sun's Java 6 VM) writes a small file when the build process is done, deletes it, and re-writes it about a dozen times (it's some Eclipse metadata file about property indexes that I don't completely understand--not part of my project). There was no apparent delay doing this under 2.6.17/ahci, but with 2.6.20/piix it takes about 5 seconds and (one) CPU is hammered the whole time. And Eclipse does incremental compilation all the time (whenever you save a resource). Java thread dumps during the big pause point to a thread waiting to close the file stream or channel, which shouldn't take that long for a 200 byte file. -- Shaw Terwilliger <`echo sterwill1io2nu | tr 12 @.`> -- ata_piix used instead of AHCI for Mac Pro https://launchpad.net/bugs/96692 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
