I tried to measure the impact of ionice on updatedb when running in parallel with a full Eclipse workspace rebuild, a CPU- and disk-intensive process. Results below, there are two measurements per item (this is Gutsy on a Pentium M 2GHz notebook, 7200RPM disk): Build alone: 50s, 52s Build with updatedb: 3min20s, 5min17s Build with ionice -c3 updatedb: 4min30s, 2min44s
So there appears to be only a minimal improvement with ionice, if there is an improvement at all (given the variability of the result, I would have to perform more measurements per item). The man page of ionice states that it works with the CFQ IO scheduler. How do I know which scheduler I am running, and how do I change it? I think it would be really nice to solve this updatedb issue, as it really does give users a negative sensation. I use to completely disable updatedb when I install Ubuntu for non-geeks. Anyway, I think most non- geeks will never use locate... -- slocate daily anacron job makes system feel slow https://bugs.launchpad.net/bugs/13671 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
