Machine-specific performance problem

Machine-specific performance problem

[Glenn Proctor]

Hi

I'm using cygwin to develop a system which is about to go live. Everything
works fine, but one of the machines - unfortunately the production one -
seems much slower than the others I've tried it on.

The problem machine runs NT, and has a 1.2Ghz processor and 1Gb of RAM. It
runs cygwin tools (both interactively and in scripts) at around one-fifth
to one-tenth of the speed of my development machine, which has a 600Mhz
processor and 256Mb of RAM.

There are various other differences between the machines - installed
applications, drive partitioning etc.

My problem is that I don't really know where do start diagnosing the
problem - has anyone else seen this disparity, and if so, what was it
caused by?

Thanks in advance

Glenn.

This might come about from inappropriate path order, from running certain
anti-virus command line checkers, from fragmentation or registry errors...

Tim

Can you clarify what you mean by "innappropriate path order"?

Your system administrators may have other ideas, but you would like to have
network mounts at the back end of your search path, and you would like
cygwin.bat to make its additions to the path on the front end, at least
ahead of any additions which Microsoft installed software like Visual Studio
has made to your basic Windows paths.

The three Cygwin directories are at the beginning of the path on both
machines, and there aren't any network drives anywhere in the path.

The hunt continues :)

Thanks

Examine your path and make sure Cygwin is at the front.  Also, make sure
you don't have network paths in there.  The FAQ can help you out with 
configuration issues that can affect performance.

Do you know which operations tend to be slower on the machin which
experiences the slowdown.
