Cygwin build system SOOOO SLOOOWWWW ???

[Steve Johnson]

Greetings To All,

We've been using Cygwin for many years to host our software build  
system on Win32.  The system is built on top of gmake.  We use the  
same gmake system on MacOSX, Linux, and Solaris.  Building under  
Cygwin has always been slower than on true *nix platforms.  This is  
expected, and we've lived with it with little problem.

In the last year or so, however, the Cygwin port has gotten slower  
and slower, to the point that building the PC version of our software  
is PAINFUL.  We've been changing the system, so maybe it's due to  
something we've added, but the other platforms remain speedy.  This  
leads me to two flavors of questions for the group...

1) How can I tell what Cygwin is doing?  Is there a tool that will  
tell me what tool is actually running at any given time?  Is there  
any way to tell what Cygwin is doing down in its guts?  Does anyone  
have any other suggestions as to how I might get to the bottom of this?

2) Has anyone else experienced speed problems with Cygwin?  Has  
anybody else felt that Cygwin has gotten slower over the last year or  
so?  Are there any guidelines or "tricks" for getting Cygwin to run  
faster?

Thanks in advance for any feedback that might help me speed up my  
builds.

PS: In case anyone wonders...we run the Mickeysoft compiler on Win  
rather than GCC.  We run GCC everywhere else.  This isn't the problem  
though, because even non-compile ops (installation, testing, doc  
building, etc) are way slow now under Cygwin.
