Yep. This is pretty much what I expected. Now we'll see a stream of people commenting on slowness and speculating on the cause without spending any time to actually figure out what the cause might be. >Somebody mentioned that malloc implementation could be the problem. >Dunno.

If you don't like the way I communicate, just delete my email. It's pretty simple. I'm also not interested in being tech support for a commercial enterprise which has a large user base who needs urgent help with a "serious problem". But, the nice thing about free software is that it doesn't matter what I want. Anyone here can help. I'm just one person. I'm certainly not going to stop anyone who wants to dig in. Asserting that people can back up unsubstantiated surmises by building the software and actually verifying for themselves is one of the basic advantages of free software. As painful as it is for most people, if there is an issue that bothers you about cygwin, you really can take some time to look into it yourself rather than relying on the random kindness of strangers. Think of what a hero you'll be if you figure out a way to improve cygwin's "slowness". -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
