I had a problem with a sata disk under heavy I/O ... response time degraded when loading/starting new applications (... until the disk finally freezed).
I solved my problem by fine tunning the "pdflush" parameters... Monitor the "Dirty" values in " cat /proc/meminfo" ... if the values remain high (... are not cleaned frequently enough) then the problem might be the "pdflush" configuration. If the problem is the "pdflush" then check this link : https://bugs.launchpad.net/ubuntu/+bug/270794/comments/12 ... I hope it helps. -- Very poor desktop response (high latency) during I/O-load with SATA+NCQ https://bugs.launchpad.net/bugs/343371 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
