Me too. On Feisty: /dev/sda: Timing cached reads: 1242 MB in 2.00 seconds = 619.52 MB/sec Timing buffered disk reads: 222 MB in 3.02 seconds = 73.45 MB/sec
I booted Gutsy tribe 4 today and got very similar numbers. If I boot Edgy or Knoppix 5.01, cached read performance is very close to doubled (about 1200 MB/sec). Logs attached are from Feisty: % uname -a Linux ni 2.6.20-15-generic #2 SMP Sun Apr 15 07:36:31 UTC 2007 i686 GNU/Linux I am willing to provide logs from Gutsy or Edgy or perform tests under them, insofar as I'm able. Actions like grepping through a large directory are very slow, so I'm interested in any solution. Was really hoping Gutsy would just solve it. :( ** Attachment added: "dmesg.log" http://launchpadlibrarian.net/8928852/dmesg.log -- read from cache is much slower with feisty than all previous ubuntu versions https://bugs.launchpad.net/bugs/90531 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
