Go up one level in this thread


I have very little experience with majority of the stuff you wrote about (I am
software developer who never wrote any network or GUI code), but even I can
address several your objections. See below.

Wrong. Use fibers. They are supported starting from NT 3.51, and I assume they
are exactly what you want.

Some of 6-man TBs were generated at a 8-CPUs NT box. 16 CPUs boxes are being
produced now. Yes, that's less than 256 CPUs, but more than 4.

You are wrong again. *Any* NT can handle 64-bit files, contrary to 32-bit Linux.
Once again, 6-man TBs with 5Gb files (uncompressed) were generated on a NT box.
