Subject:	FW: trying to understand poor performance of make + cygwin on W2K
Date:	Wed, 1 May 2002 08:34:07 -0400
MIME-Version:	1.0

I'm trying gain some performance for our build process (cygwin on win2k)
and have compared it to the same make on linux

If I completely build our tree (about 
then rerun the make from the top it takes 9.5 seconds on linux 

if I do the same test on the same machine running
(machine P3-500 512MB)
win2k +cygwin 1.3.9 +make (3.79.1)
it takes 3.5 minutes

so 210 seconds versus 9 seconds.
all its doing is recursing down the tree, testing the dependancies
and determining it has nothing to do, so its not compiling anything
its all make +cygwin, I think (ie no gcc invoked anywhere)

any ideas on what to try?
is this an issue with the cygwin fork() implementation??
is this as good as it gets

ken
