Hi, I'm suffering the same bug on my systems. I'm providing logs from my laptop, a Dell Inspiron 510m. Prior to Feisty, cached reads approached 1500MB/s. Using kernel version 2.6.20-9-generic, everything up-to-date.
[EMAIL PROTECTED]:~/slowcache$ uname -a Linux inspiron 2.6.20-9-generic #2 SMP Mon Feb 26 03:01:44 UTC 2007 i686 GNU/Linux [EMAIL PROTECTED]:~/slowcache$ sudo hdparm -Tt /dev/hda /dev/hda: Timing cached reads: 1046 MB in 2.00 seconds = 522.33 MB/sec Timing buffered disk reads: 80 MB in 3.09 seconds = 25.85 MB/sec ** Attachment added: "dmesg log" http://librarian.launchpad.net/6726334/dmesg.log -- read from cache is much slower with feisty than all previous ubuntu versions https://launchpad.net/bugs/90531 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
