[REBOL] Re: New competition: do you accept the challenge?! :-)

From: dhsunanda:g:mail at: 6-Nov-2007 15:32

Two very quick changes just to get into the spirit of the competition: 1. pre-allocate all space needed to the strings 2. use insert tail rather than append (append is not native in R2) Runs in about 65% of the time of the original. Still not as close as Java, but it was only a minute's work. Someone is sure to do much better. I suspect both Java and REBOL depend on the string handling libraries of the compiler they are compiled under. That may mean the relative timings will vary according to platform and release. Sunanda Changed code..... print "START..." s1: now str: make string! 5000 finale: make string! 50000 repeat i 10000 [ clear str repeat j 500 [ insert tail str reduce [i "," j "-"] ] insert tail finale copy/part skip str 1 4 ] print "STOP!" print length? finale print (now/time - s1/time)
