the time output does looks like you have higher cpu usage for some reason, so i agree with Shachar on this.

you can also try to pinpoint the place the cpu is spent.
strace and/or ltrace with the '-f -c' flags can help.
I'm not sure about ltrace, but strace will not help. Most of the time is spent in user space, not in the kernel.

Strace may help if the problem is time spent in another process (i.e. - while the main process is sleeping), but it seems Noam has already tried that one and failed to spot any obvious candidates.

    I know the time difference doesn't look too bad, but take a
    bigger code set:

    Fast:
    real    0m1.682s
    user    0m1.584s
    sys    0m0.064s

    Slow:
    real    0m16.730s
    user    0m9.345s
    sys    0m0.096s

    These times spell "CPU intensive". Does your library do anything
    special? If you try to import a dummy library, does this still
    happen?
