I have two core processor 3 GB RAM 512 MB Video Windows XP Professional
With version 4.5, the CPU load 0% , with version 4.6  50% when I just turned on the Mach3.

I found the document "Tormach machine controller"
which focuses on the problem of choosing a computer for Mach3.
They use the LTP port, whether it is possible to apply to the ethernet port.
They recommend using the computer on a new Intel Atom processors.
Steve what motherboard you're using?

Thank you.

I bought another computer.
Intel D945GCLF2D Atom 330 1.6Ghz 2Gb RAM.
Installed Windows XP Sp3 latest drivers, GalilTools, Mach3 3.043.062.
And I try to use version 4.5 and 4.6. With version 4.6 25% CPU load with version 4.5 0%
To verify that the loads the processor, downloaded program ProcessExplorer
for it can be seen that galil.dll version 4.6 or the libraries it uses loads the processor.
And version 4.6 uses the library hal.dll, and the version 4.5 does not.
Steve what can advise?

The difference between 4.5 and 4.6 is the Galil communication libraries.  I don't know what may be causing the CPU load.  I simply don't see it on my machine at all.  But...  25% is not 100%, so it should run fine.
