I ran iperf between my windows and linux clients (two comparable
machines bouncing off of a cisco switch). Result was 82.6Mbits/sec. I
think the network is fine.

I downloaded Cenatek RAMDiskXP and checked out into the RAM disk. Time
was 1m 35s. I don't know anything about this product other than there
is a free trial download and it must be faster than writing to the
physical disk. (It should be faster than the Linux disk).

How much of an affect would <CR><LF> conversion take? That is the only
work that I can think of that Windows is doing and Linux is not. I
would not expect it to be free, but I can't imagine it dominating the
run time either.

I'm currently creating another repository from the same cvs archive
with: cvs2svn --trunk-only --no-default-eol --keywords-off

If that does what I think it will do, I'll post the results tomorrow.
