[REBOL] Report on WinCE Rebol --- Speed Comparison

From: dness::home::com at: 27-Jun-2001 22:23

Since questions have been raised here about REBOL on a Pocket PC class machine, I thought it might be useful to run and simple experiment and report on it here. The Experiment I adapted the distributed `factorial.r' program to calculate a fibonacci number. I did this in the most straightforward way (involving double recursion) in a simple attempt to produce a program that would consume a detectable amount of execution time so that comparisons could be made. The Contexts I ran the program in five different contexts: Context 1: Rebol\View on a 333mhz iDOT computer with 384mb ram Context 2: Rebol Core on the same machine Context 3: Rebol\View on an 800mhz Sony computer with 512mb ram Context 4: Rebol Core on the same machine Context 5: Rebol\core on a 206mhz Compaq iPAQ with 32mb In all cases f(25) was calculated and returned (no surprise here) the correct result. The Results Context Timing 1 333View 13 seconds 2 333Core 10 seconds 3 800View 3 seconds 4 800Core 2 seconds 5 iPAQ 1min 16seconds For comparison with `other worlds' I used the same algorithm coded in both the `J' and `K' languages (mathematical array processing interpretive languages both related to APL). The timings were: J 5.6 seconds and K 0.6 seconds. I'd be happy to answer any questions or perform other experiments if it would be meaningful to anyone.
