John, just cause the machines we use to serve web content to our
clients doesn't use the grade of equipment you prefer to use, and can
afford, doesn't mean equipment that other people use is inferior, or
I have a problem with one of my machines, and have narrowed down that
it could either be the CPU, RAM or motherboard, but before I take it
back to the suppliers, I need to know what is wrong. They will switch
it on, and see that it works. But it's not taking the load that I
expect it could. In fact, it's not taking the same load as a machine
with a Intel E6750 Core 2 Duo & 4GB RAM. This server should be 2 - 4
times faster & handle 2 - 4 times the load of the E6750, yet it
doesn't and I need to know why. I don't appreciate being told that the
hardware I have if inferior.
