Hello, all ...
In my rapture at discovering kqueue / kevent are part of OSX, I wrote
a simple C++ program to create a specified # of files in a specified
directory, and then monitor them for changes. I then wrote a simple
Perl script to, well, change 'em. All is cool in kqueue-land, with
hundreds (soon to test thousands, then tens of thousands, over a
network, across a moat, with a goat, etc). Now, I want to see how
scaleable it is. Is there a tool (ktrace maybe?) that I can use to
measure the latency between a file being changed, and my C++ app
being notified of it? I can do some basic timing in my Perl code,
saying "I changed X files in N seconds" and my C++ code, saying "I
processed X notifications in N seconds", and extrapolate, but silly
me wants more.
Regards,
John
