- Subject: Cygwin signal bandwidth
While working on a project, I had the need to run a function every
millisecond. So, my first attempt was to fork() and then loop sending a
signal then delaying 1ms. What I found was that a cygwin process can
only receive about 100 signals/sec before it uses up 100% of the
processor (on a PIII/850MHz).
Is it reasonable for me to conclude that cygwin uses about 8,000,000
cycles to process a single signal, or have I done something wrong?
