But when trying to copy a 1Gb file on the client's mounted

No matter how many nodes (currently the volume is only with
its own <br>
node) the speed is really slow. For testing purposes, i made a
volume <br>
with only one node, without any replication - however the
speed is <br>
still ~500kb/s. The cloud servers are limited to 30Gbit/s but
still <br>
the traffic when writing to the node is ~500kb/s <br>
<br>
i'm using 3.3.1 glusterfsd with kernel 2.6.18-348.el5xen and i
need <br>
to know if the the problem is within the kernel. <br>

I don't think it is a problem with gluster; I never used el5 for
this, but I doubt there's an inherent problem with it either.
That speed limit looks odd to me and I think it's somewhere in
your setup. <br>
Have you done any actual speed tests in the VMs? <br>
