Hi,
Apologies for not getting back sooner, I have been doing soem investigations withour network set-up on the Media Server and also the buffer sizes, I incresed the amount of Buffers to 256 from 16 which gave a better performance across the board but this was still slow on the VM's and other clients using my media server.
I moved several backups through the Linux Master server and saw a dramatic rise in the throughput, the Windows Media server still produces upto 50% less throughput though.
We believe that this is a problem with the actual server, this is an HP Blade which uses it's own internal switch through the blade chassis and then through to the main LAN, a call to HP is being opened about this and we are also looking at putting in a Mezanine Card and having a direct connection on the LAN to see if this improves the performance.
Will keep you updated
Kev
