There have been new commits which should (theoretically atleast) improve
read performance while read-ahead loaded in the client. Also you should try
loading booster on the server side so that I/O happens from client's address
space directly to the server (bypassing kernel/fuse/glusterfs client). The
configuration is a bit tricky and yet to be documented, but our tests so far
have shown good results so far.

It always takes longer than you expect, even when you take into account
Hofstadter's Law.
