Hi!
I'm trying to profile an application that I believe is blocking on I/O
for a significant amount of time. In trying to dig down where this
happens, I profiled the application with hotshot. The results are not
really usable however as it seems to display the amount of CPU time
which for my application is much lower than the total run time.
Is possible to use hotshot with wall clock time, i.e. is it possible to
have the code fragment below show one second as opposed to zero? The old
profiler seems to have functionality choosing a timer function but it
crashed on my code.
<cut>
import os
import time
import hotshot
import hotshot.stats
import tempfile
def profile(call, *args):
"""Profile function `call', invoked with `args'."""
fd, fprof = tempfile.mkstemp()
os.close(fd)
profiler = hotshot.Profile(fprof)
profiler.runcall(call, *args)
profiler.close()
stats = hotshot.stats.load(fprof)
stats.strip_dirs().sort_stats('time').print_stats()
os.remove(fprof)
profile(time.sleep, 1)
</cut>
Regards,
