[Linux-cluster] dissapointed with GFS performance

Is there any way to "tune" gfs so that it will run faster? I have a GFS
partition with data on it which our internal order system accesses. It
is a text based (command line) driven application which is installed on
the local disks, and accesses the data through the /data directory which
is mounted on the GFS partition. When I run the program, I can notice
latency between menu changes. To confirm that it is GFS causing the
latency, I created an ext3 partition on my SAN, unmounted /data from the
GFS partition, then mounted /data to the newly created EXT3 partition. I
placed the exact same data on this EXT3 partition, fired up my
application, and it whips through menu changes instantly. This tells me
that the SAN is fast, but GFS is not. 


What can I do to speed up GFS, or is this just the way it is?
