4 dual core AMD opterons 8GB RAM Disk on entry level SAN
2 quad core Intel 32GB RAM local disk arrays.
Generally these servers perform similarly.
My question is - is it the extra memory on the development machine which is making the backup so fast? The CPU cores all run at about 30% during the backup, whereas only about 4% on the live server.
Or is it more likely to be our disk arrangement.
