[Linux-cluster] GFS performance

[Ciril Ignatious T]

Dear all

I have two nodes sharing a GFS 6.1 File system partition in Redhat 
Advanced Server 4.0 update1.
If both servers are accessing the same file in the shared volume at the 
same time by an application in the nodes ,what abt the performance of 
the machines.

Also whether there is any bench marks for measuring the GFS shared 
storage performance.

Regards

Ciril
