Here's my version of that. The first run is on a 1MB string will all tests enabled.

The second run is on a 1GB string with the classic and s/// solutions disable because life's too short :)

C:\test>1046579 -N=2**20 1048576 Rate single long classic str translate single 1.72/s -- -99% -100% -100% -100% long 134/s 7707% -- -71% -79% -81% classic 468/s 27047% 248% -- -26% -33% str 632/s 36579% 370% 35% -- -9% translate 695/s 40233% 417% 49% 10% -- C:\test>1046579 -N=2**30 1073741824 (warning: too few iterations for a reliable count) (warning: too few iterations for a reliable count) s/iter str translate str 1.96 -- -21% translate 1.54 27% --

The modified code:


With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'
Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
