in my plot,

if I comment 'set logscale x;';

yes the line perfectly straight, but my X axis start after 1x10e6 

so my X axis list is:

0
1x10e7
2x10e7
3x10e7
4x10e7
5x10e7
6x10e7
7x10e7
8x10e7
9x10e7
1x10e8

its same as my reply for choroba comment, what is "1MB limit" before it slowing down ?

and why beyond 1Mb number,perl (and now similiar ruby) slowing down more extreme than another language

and this 1MB limit is not just about limit of $i but like the whole loop operation 

in previous comment, using this variant:

time perl -e 'for($i=0;$i<=1000;$i++){for($j=0;$j<=1000;$j++){for($k
+=0;$k<=100;$k++){}}}'

have the same time with just using 1 loop with $i=1x10e8

I tought if I make the loop with smaller number It will break 1MB limit, but it's not...

so i still want to find this "magic setting" (maybe through ENV or system setting ) that can increase this 1MB limit, and hoping without need to hack perl core or recompile from source
