My company is trying to setup a development environment
using Cygwin on a server running Citrix.  This allows
multiple users to log into the Citrix server and it
looks to them like they have their own machine. 
However, in the course of testing the installation of
our development packages (including Cygwin) we noticed
that the build was taking many times longer than on a
local machine.  After producing some basic benchmarks
to determine how far off performance was, I attempted a
series of low level tests to try an narrow down the
bottleneck.  One of the tests was a simple while loop
which counted to 100.  This test took approximatly 30
seconds in Cygwin under Citrix and only 4 seconds in
Cygwin on a local machine.  In addition, I created a
DOS batch file that used a goto loop to count to 100. 
This took only 3 seconds in the DOS shell under Citrix
and about the same amount of time on my local machine.

I have not been able to find any information regarding
this either on the web or on the Cygwin site.  If
anyone could provide any insight as to why Cygwin seems
to be so slow under Citrx I would greatly appreciate it.

Dave
