It is fuse 2.8.0-pre3 that I tried with the patch you mentioned. When I tested I used 1M block sizes for a count of 100 and got 1.4MB/s when that was done over NFS. That was using both standard NFS with direct-io disabled and unfs3 with direct-io enabled. The same test of 1M blocks for a count of 100 made for 45MB/s on the same filesystem, but the local gluster mount instead of over NFS. When using NFS to one of the same machines as well, but local-disk mount I get around 50MB/s.

Just wanted to know what are the metrics you observed while testing?, block size in which writes/read were measured during testing?. etc, Regards -- Harshavardhana Z Research Inc http://www.zresearch.com/ On Thu, Jul 9, 2009 at 11:45 PM, Justice London <jlondon at lawinfo.com> wrote: Well, mostly it seems to be on the throughput. I haven't really measured for metadata improvements yet. Of note, is that NFS is now working, but it appears to be EXTREMELY slow.

Just curious, are the observed performance improvements in terms of IO throughput or metadata latency?
