I have had this problem for a while now and just fixed it by adding "noatime,nodiratime" to the mount options in fstab, as suggested at http://kerneltrap.org/node/14148 .
The problem was on a SATA drive I use for storage. Copying a 676mb file from an IDE to the SATA drive before the fix: > time cp test.tar /storage/. real 1m38.573s user 0m0.032s sys 0m4.132s And after: > time cp test.tar /storage/. real 0m7.128s user 0m0.004s sys 0m2.892s The cpu usage during transfer was about 3%, now it ranges from 15-50%. I don't notice it, but I just thought I should say. -- Slow SATA performance https://bugs.launchpad.net/bugs/119730 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
