Copying 155GB data to external usb drive with NTFS and cfq scheduler starts with around 30MB/s and drops to 9MB/s after transfering 10 to 15 GB and slows down to 2MB/s if I wait a little bit longer. Using Ext3 on the same disk and using cfq scheduler the datarate is around 22MB/s for the first 90 to 100GB and then drops down to 2MB/s. While copying the mount process was on top of cpu usage with around 4% and my desktop applications reacted a little bit slow. Using noop scheduler I get constant transfer rates of 21MB/s and no desktop starvation. -- elevator=cfq (default) cause starvation https://bugs.launchpad.net/bugs/381300 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
