[REBOL] Re: New competition: do you accept the challenge?! :-)
From: ale870::gmail::com at: 7-Nov-2007 1:02
yes, now I understand what you say.
My main target is testing how fast Rebol can handle strings. I compared it
with java simply because java is fast, but not so fast like a real compiled
application (e.g.: C++, C, Pascal, ADA, Oberon, etc...).
The result is import only because that one is the only way I have to be sure
that two different programming languages are implementing the same
algorithms (so I can compare them).
I think we need to optimize Rebol code using specific tokens (e.g.: I used
append
but now I discovered that "insert tail" is faster because it is
native... this is an important optimization).
Obviously, if can change the algorithm and you reach the same result, maybe
you didn't work on Rebol code, but on programming logic. It means we should
apply such optimization even in the java code.
If you have a better idea or suggestions in order to check it, please don't
hesitate to help me to find a better way (I started this "competition" since
I'm creating some rebol cgi, and I asked to myself if rebol will be faster
or slower than java ). Of course java server is another technology (not
cgi), but now I wish to analyze tha language performances based on the same
logic and algorithms.
I think we could apply a different logic/algorithms only if we find a rebol
trick that could be never applied in java since the "concept" could not be
immplemented in java self.
