This one can easy be a new thread, but let say it anyway

I run simple dd test like this:

dd if=/dev/zero of=writetest bs=8k count=131072


In NFS

131072+0 registros de entrada
131072+0 registros de saída
1073741824 bytes (1,1 GB) copiados, 17,1806 s, 62,5 MB/s

In GlusterFS

131072+0 records in
131072+0 records out
1073741824 bytes (1.1 GB) copied, 9.13338 s, 118 MB/s

And with conv=fsync

GlusterFS

dd if=/dev/zero of=writetest bs=8k count=131072 conv=fsync
131072+0 records in
131072+0 records out
1073741824 bytes (1.1 GB) copied, 11.0702 s, 97.0 MB/s

NFS

 dd if=/dev/zero of=writetest bs=8k count=131072 conv=fsync
131072+0 registros de entrada
131072+0 registros de saída
1073741824 bytes (1,1 GB) copiados, 14,2901 s, 75,1 MB/s

Both servers are PowerEdge R430 with SAS HD 7.2 K RPM, with 16 GB of
memory, linked with 1 GB direct cable...

GlusterFS won?!?!

I would like to hear some opnions...

Thanks a lot
