 From our testing we found gluster with many small files to be rather 
slow (GigE). Each open() will go over the network and will effectively 
kill read performance (5-7 MB/sec). We tried to serve webapps with many 
small files and startup time was not tolerable.

Of course, you need to test yourself ;)
