This issue appears to still be present on a fresh install of Hardy (Ubuntu 8.04) as well.
I'm in the process of setting up a new server, and I applied the "gross hack" posted by Kees Cook. I have applied this to my desktop system a while back, but was hoping that it would have been fixed by now. Just to be sure this hasn't been fixed in some other way, I ran some quick read performance tests with "hdparm -t /dev/vg/lv". I tried values from 256 (default) up to 16384. I confirmed that 8192 seems to give the best performance (57 MB/sec), and 256 gives the lowest performance (29 MB/sec). Anybody have an update on when this will get fixed officially? -- very sub-optimal default readahead settings on device and unused readahead setting in LVM https://bugs.launchpad.net/bugs/129488 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
