[Gluster-users] GlusterFS performance

Thanks for your reply.

No matter how many nodes (currently the volume is only with its own 
node) the speed is really slow. For testing purposes, i made a volume 
with only one node, without any replication - however the speed is still 
~500kb/s. The cloud servers are limited to 30Gbit/s but still the 
traffic when writing to the node is ~500kb/s

i'm using 3.3.1 glusterfsd with kernel 2.6.18-348.el5xen and i need to 
know if the the problem is within the kernel.

Find out about our new Cloud service - Cloudware.bg 
Access anywhere. Manage it yourself. Pay as you go.
