[Linux-cluster] GFS: more simple performance numbers



I've rerun the simple performance tests originally run by Daniel McNeil with 
the addition of the gulm lock manager on the 2.6.8.1 kernel and GFS 6.0 on 
the 2.4.21-20.EL kernel.

Notes:
======
Storage:        RAID Array Tornado- Model: F4 V2.0
HBA:            QLA2310
Switch:         Brocade Silkworm 3200
Nodes:          Dual Intel Xeon 2.40Ghz
                2GB memory
                100Mbs Ethernet
                2.6.8.1 Kernel/2.4.21-20.EL Kernel (with gfs 6)
GuLM:           3-node cluster, 1 external dedicated lock manager
DLM:            3-node cluster
LVM:            Not used
