I am using Gluster version 3.2.1.1 In my 4 node cluster setup, one of my node on which I am performing test run is physical sever of HP proliant DL 380 G5 having RHEL 5.5 OS ,is having 1000Mbps network. Other three nodes are hosted on Windows 2008 R2 on virtual machine(VM ware Application) , host machine network is of 1Gbps What are you virtual machines? Linux, I suppose? A few aspects of your setup makes the comparison unfair - 1. Since you run untar on the local file system on a physical server, the is a possibility to see the effect of write caching. 2. Since glusterfs is working on VMs, the comparison of its performance with that on a physical server is not fair. 3. The VMs are hosted on a system with low network bandwidth. 4. The IO throughput inside a VM is limited by the throughput of the host file system, in this case - a Windows filesystem (NTFS) ? What is the amount of RAM on the Windows system hosting the VMs?

Re: [Gluster-users] Performance on GlusterFS
Can you run dd if=/dev/zero of=/junk bs=128k count=1 oflag=direct on the local file system and then run dd if=/dev/zero of=/client-mount/junk bs=128k count=1 oflag=direct on gluster mounted file system? compare them What's your disk configuration on RHEL in terms of RAID, # of disks etc. And are those 4 servers sharing the same local storage?

It would help if you can post the output of gluster volume info, to start with. Are you using some benchmark to compare GlusterFS performance with local filesystem performance?
