[Gluster-users] GlusterFS performance

Well, lookee what I found. Since I am not smart enough to know exactly 
when to give up, I installed GlusterFS 3.3.0 in place of 3.2.6 on both 
servers and clients. Using the tests (file foo.bar being on the GlusterFS 

 	dd if=/dev/zero of=foo.bar bs=1024k count=1000
 	dd if=foo.bar of=/dev/null bs=1024k

I find the following client performance, using a distributed volume of 2 
bricks and no replication, and with no further tuning:

GlusterFS 3.2.6:
 	read = 13 MB/sec
 	write = 45 MB/sec

GlusterFS 3.3.0:
 	read = 54 MB/sec
 	write = 97 MB/sec

Firefox, running from a GlusterFS-based home volume, is also nearly three 
times faster to open with 3.3.0 than with 3.2.6 (I have a bunch of tabs, 
and it now opens in 4 seconds vs 11 seconds).

Read performance is still a bit lower than I'd like, but what an 
improvement. And I have no idea why.
