Message-ID: <9hpdkf$nhb$1@s1.read.news.oleane.net> (raw)
I have a multi-tasks, IO intensive program that I ran under gprof to identify bottlenecks (GNAT 3.13p under Win95).
Although the (real) execution time is about 3mn 30s, gprof shows only 6 samples (at 0.01s. period!).
My explanation is that interrupts (and therefore gprof sampling) are suspended during IO suspension, and that all time spent in IO
procedures escapes analysis. Is this correct ? It would be terribly annoying in my case...
