Any idea how to actually build syntetic but close to real benchmark for this? For example: Usual web server does: 1) forks 2) reads a bunch of small files from disk for some time 3) forks some cgi scripts 4) dies If i write a test in C doing somthing like this and run very many of then is parallel for, say, 1 hour and then count how many interation have been done with HZ=100 and with HZ=1000 will it be a good test for this? -- Regards Artem
