The results are very surprising, and most likely wrong. It would mean that just changing it++ to ++it in a loop removes 80% of executed code from the loop. It can make things faster, but such big improvement is hard to believe. I suggest you repeat the test with exactly the same conditions for both of the variants (i.e. reboot, do the test; change to the other variant, reboot, do the test exactly the same way). -- Lubos Lunak KDE developer --------------------------------------------------------------------- SuSE CR, s.r.o. e-mail: [email protected] , [email protected] Drahobejlova 27 tel: +420 2 9654 2373 190 00 Praha 9 fax: +420 2 9654 2374 Czech Republic http://www.suse.cz/
