Hello, I installed a trial version of Gluster Storage Software Appliance last week. At the moment I do some performance tests on the server. I use Ubuntu Server 11.10 as OS. Hardware (2x): -AMD Opteron Quad Core 2.2GHz -16GB RAM -12x WD 2TB HDD @ 7200rpm -10Gbit link between the servers I use zfs as filesystem. Glusterfs version 3.2.1, but I also installed 3.2.4 for testing (same behaviour). ZFS is mounted to /data: dd if=/dev/zero of=/data/LUN0 bs=1M count=20240 21223178240 Bytes (21 GB) kopiert, 13.6647 s, 1.6 GB/s create a glusterfs volume (without replication for testing local speed): gluster volume create test-volume san0:/data/test-volume and mount: mount -t glusterfs san0:/test-volume /mnt dd if=/dev/zero of=/mnt/LUN0 bs=1M count=20240 21223178240 Bytes (21 GB) kopiert, 79.0924 s, 268 MB/s I also do some tests with bonnie++. The result you can find as attachment. As you can see, glusterfs mount is much slower than the local zfs mount. During the dd and bonnie++ tests (glusterfs mount) the cpu load for glusterd and glusterfs processes is much more than 100% (150%-170%) Is this the normal behaviour of glusterfs?? Or Is the Quad core cpu to slow?? Thank you for help.
