Hi Daniel,

Please find the comments inline.

Yes, I did that. However the CPU usage gets very high (100% for all cores)

>From what I understand, you have started the Gluster Object Storage on one
of the GlusterFS servers and then increased the Proxy server count. If there
are any other GlusterFS servers then you can start Gluster Object Storage on
those machines and do some load balancing over all these machines by using
Pound, nginx etc. This will help reduce the cpu usage of the current machine
and also utilize the other server resources.

I read the documentation and there's no mention about separating the

There is a difference here how the swift and Gluster Object Storage work.
Currently, all the servers (proxy, auth, object, etc) are all coupled to
each other and hence they cannot be seperated. This can be emulated by
configuring the setup as I mentioned above.

Hope this helps.
