Refresh speed of Rebol/View...WAS:Re: deceleration !
[1/3] from: cyphre:seznam:cz at: 14-Oct-2002 16:25
Hi list,
As there was discussion about speed of Rebol/View and I'm still interested
how fast View really is so I tried to make a little script which
measures(more or less exact ;-)) the framerate of plain rebol face in
different sizes. I would like to know how fast is Rebol's framebuffer on
different machines/platforms etc. so if you are interested run the following
script:
do http://www.rebol.cz/~cyphre/benchmark.r
and don't forget to fill-in the(anonymous) result form at the end of all
tests with at least little technical info like CPU,GFX card, OS version (or
whatever you want to tell me ;-) ) and submit to my email address. I will
publish all gathered results on the list at the beginning of the next month.
Thanks in advance for your interest!
regards,
Cyphre

Re: Cyphre's benchmark.r
Two things intrigued me from the benchmarks I got - one was the fact that
Win2k seems to have been limited intentionally to 50fps and the other was
the insane speeds BeOS gave in the 320x240 and 640x480 tests.
Results below:
All versions below tested on the same machine.
hardware specs as follows:
AMD 1.4Ghz (not the 1400+)

Problems...
** Script Error: send has no refinement called subject
** Where: func [face value][send/subject [cyphre--volny--cz] reform [mach
newline newline rslt newline com/text] "Benchmark results" quit]
** Near: send/subject [cyphre--volny--cz] reform [mach newline newline
rslt newline com/text] "Benchmark results"
A REBOL-beta script perhaps? Hmmm. Perhaps you should ask what REBOL
version they're using, too. The betas are supposed to be faster,
aren't they?
