You didn't provide your current config or what version you are running but you may find this useful: http://www.gluster.org/community/documentation/index.php/Gluster_3.2:_Tuning_Volume_Options I'd be interested to hear what happens if you repeat your tests with some performance settings changed. I will be configuring Gluster in an HPC cluster with ~83 million files and I'm going to run into the 'lots of small files on replica sucks' problem. Also, here's my testing but it was on a very limited network (stuck on a 100Mb switch): https://docs.google.com/document/d/1PpszoTd6CqQaaQKavSagw8_ySsEI_sXcCa5z4ubWgLU/edit Jeff White - Linux/Unix Systems Engineer University of Pittsburgh - CSSD On 12/21/2011 03:09 AM, Ulli Horlacher wrote: > I have set up my first 2 node gluster with 1 GbE for testing. > Thanks to very good documentation, it was easy. > > My aim is to use gluster for LXC VM replication. > Write performance is a critical issue for me. > > Test case 1: copying 22000 files with 1 GB totally > > local disc/filesystem: 47 MB/s > NFS3: 13 MB/s > glusterfs: 4 MB/s > > > Test case 2: writing one file with 1 GB > > local disc/filesystem: 123 MB/s > NFS3: 95 MB/s > glusterfs: 67 MB/s > > > Especially the result of test case 1 is very disappointing.
