GlusterFS?

[Jerker Nyberg]

Hi,

I compared local disk, NFS and GlusterFS with bonnie++ on my old nodes 
(Athlon 1 GHz), and seeks/s was 43 seeks/s compared to ~180 for local disk 
and ordinary NFS. I guess FUSE etc have overhead compared to a a kernel 
solution.

For large file transfers both NFS and GlusterFS saturated a fast ethernet 
network. When using 200 Mbit/s NFS scaled up, but not really GlusterFS. I 
do however believe that this is a limitation processors but I'm not really 
sure.

I will do some tests the following week with nodes with P4 2.8 GHz and 
gigabit. Here are the old results anyway:

(The main good thing with GlusterFS is of course that many servers may be 
used in parallell so even if a single server has slightly more overhead 
than a kernel solution with NFS, more servers may be added and the files 
be distributed among them.)

However, I havn't tried MogileFS yet. :)

Jerker Nyberg.
