Re: select() too slow

I'm afraid that this is not a very good bug report, as you have not
attempted to describe WHAT is too slow, and have not provided a simple
test case that compiles out of the box, with timing numbers on the test
case compared between Linux and Cygwin. Cygwin is only as fast as the
underlying Windows system calls permit it to be. Also, cygwin is open
source. Go look at the source code to select() and you will see that it
is very complex, since Windows does not provide good hooks for an
efficient implementation. If you would like it to be faster, then
consider writing a patch to cygwin that can speed it up.


first of all this is not a bug report, but just trying to understand what might be the problem.
If I knew what the problem is I was not asking if there is any known issue, a fix, or something.
I've read the archives before posting and there are some guys with similar problems but no answers.

I know that the select() function on windows is quite different and not very handy.
One thing is weird for sure, similar code works just fine on Unix but is not very performante on Windows.

I want to know if someone have found some way to deal with this strange issue.
