And rm'ing a file (on ssh to the server) and playing a mp3 at the same time shouldn't make the mp3 skip 1-3 seconds should it? And I've had a stable 11mb/sec out of smb before (tweaked). > Also there is this tool called elvtune. It allowes you to "tune the I/O > elevator per blockdevice queue basis". See the man pages. > > You could try to lower the read latency for the affected devices (/dev/hda, > /dev/hdb, etc.) elvtune shows read_latency of 2048 and write_latency of 8192, that's already quite low isn't it? If not, have any example values I can test with? cat .config | grep -i tcq shows # CONFIG_BLK_DEV_IDE_TCQ is not set should I manually set it and compile? It's not in make_config. also does anyone have a lvmcreate_initrd script for lvm2? just did a bonnie++ test on the lvm volume. Seems VERY slow doesen't it.
