I'd suggest testing your system while monitoring with top and iotop 
(which should be a "yum install" away).

That should show you your bottlenecks.

It looks to me like Asterisk doesn't do compression until the call is 
ended, so recording to a compressed format would actually increase IO 
load (write, read and compress, write compressed data).
