Im using softperfect now also.

I read the whole wow folder into ram with allwaysync and then read it back to the hard drive before shut down. it does take 4 or so minutes to read from the hard drive to the ram drive but reading from the ram drive to the hard drive is under 10 seconds cause only the files that change need to be written back.

I have no problems with this set up. I have not disabled the windows swap file.
