Low resolution of cpu times returned by getrusage

Discussion in 'Python' started by Matthias Oberlaender, Jul 28, 2003.

  1. My problem is that cpu times returned by getrusage seem to be rounded to 10
    ms units (so also does time.clock).

    I never noticed such a low resolution in previous versions. Since I have not
    found similar reports on the web, it probably is not a general bug in
    (rather outdated) version 2.2.1. Any idea what could be wrong with this
    peculiar installation?

    Thanks a lot!

    Python 2.2.1 (#3, May 3 2002, 16:42:06)
    [GCC 2.95.3 20010315 (SuSE)] on linux2
    Type "help", "copyright", "credits" or "license" for more information.
    >>> import resource
    >>> print resource.getrusage(resource.RUSAGE_SELF)

    (0.01, 0.040000000000000001, 0, 0, 0, 0, 186, 410, 0, 0, 0, 0, 0, 0, 0, 0)
    >>> for i in range(1000000): pass

    ....
    >>> print resource.getrusage(resource.RUSAGE_SELF)

    (0.26999999999999996, 0.059999999999999998, 0, 0, 0, 0, 4116, 414, 0, 0, 0,
    0, 0, 0, 0, 0)
