It is expected that GFS2 would do better in this area butt this does 
*not* imply GFS(1) is not fixable. One thing would be helpful is sending 
us the benchmark (or test program that can reasonably represent your 
application IO patterns) you used to generate the performance data. Then 
we'll see what can be done from there ....
