Hello everybody:
I have some problem with performance of 1client+2server application.
The system is AS5.2, 2.6.18-92.el5PAE kernel.
GFS is 1.3.9 built on Feb 11 2009 16:07:40 ,Repository revision: glusterfs--mainline--2.5--patch-770
FUSE is fuse-2.7.3glfs10

When i writed some data into gluster directory /data1 by using dozen dd commands ,
i use "time ll -h " in /data1 with result :
real 0m8.388s
user 0m0.000s
sys 0m0.000s
How could i improve my performance ? what should i do ? waiting for your return ,thanks a lot
Could some tell me what your GFS configure?
