New submission from Serhat Sevki Dincer <jfcgauss at gmail.com>:
I wrote a tiny grep with multi-line match support, and compared its speed under
pypy 1.7 with grep and CPython 2.7.1 (on ubuntu 11.04 laptop).
No special algorithm/implementation is employed; it is bare re module.
input: Plone 4.1.2 eggs directory, size 286mb, possible processed input size is
about 75mb, processed 3958 files total
time mgrp -lcrN '\.py$' for .
time python2.7 /usr/local/bin/mgrp -lcrN '\.py$' for .
time grep -lcr --color=none --include='*.py' for .
Is the input too small to see the benefits of pypy?
