-100 is too long

#!/usr/bin/perl ## spin-up hard-disk, init cache ;) Split(); IRS_while(); IRS_map();

irate/tyerate

Rate IRS_map Split IRS_while IRS_map 7682/s -- 0.83 0.81 Split 9284/s 1.21 -- 0.97 IRS_while 9529/s 1.24 1.03 --

And from memory

my $removed = \ scalar read_file('removed.xml'); use File::Slurp; Rate IRS_map IRS_while Split IRS_map 16544/s -- -36% -49% IRS_while 25775/s 56% -- -21% Split 32686/s 98% 27% --

irate/tyerate

Rate IRS_map IRS_while Split IRS_map 16544/s -- 0.64 0.51 IRS_while 25775/s 1.56 -- 0.79 Split 32686/s 1.98 1.27 --

    Ok, I can agree with that - I don't see how that changes the results. Changed to -3.

    Rate IRS_map Split IRS_while IRS_map 9659/s -- -26% -28% Split 13017/s 35% -- -3% IRS_while 13379/s 39% 3% --

    Considering that a lot of time is in I/O (open and readline), I wonder if the differences between our results are due more to I/O characteristics on our systems than to the algorithm itself.
