Fquery

Benchmarks

So how does Fquery compare to equery? Here are some random tests.

The following results are between Fquery-0.2 (compiled with ghc-6.4-r1) and gentoolkit-0.2.1 (running Python 2.4.2). Note that Python sometimes takes longer than usual to start up, so the times are taken after multiple runs.

File Belonging to a Package

    fquery b /usr/bin/equery > /dev/null     0.15s user 0.01s system 98% cpu 0.162 total
    equery b /usr/bin/equery > /dev/null     7.80s user 0.15s system 99% cpu 7.973 total

    fquery b /etc/X11/xorg.conf > /dev/null  1.81s user 0.04s system 99% cpu 1.853 total
    equery b /etc/X11/xorg.conf > /dev/null  7.78s user 0.14s system 99% cpu 7.924 total

Note that Fquery exits as soon as it has found all of the files specified, hence the time difference between the two cases.
