[REBOL] Re: UTF-8 revisited

From: rotenca:telvia:it at: 27-Nov-2002 21:40

Hi Jan, While the first set of changes reduces the timings to about 65% What is exactly the first? the second has much lesser impact - 61% at best, which is about And the second? 0.34s for 1000 loops on "chars: sz" Latin-1 sequence (case k=1) where utf8-encode gets its best timing of 0.18. But if you try utf8-encode with a long string (>6000 chars), it becomes more slow than encode. What is the most frequent case? But breaking of the 1s barrier happened only after I completely revised the algorithm and started working from the least significant bits up. This way I could get rid of most of the tables and use hardcoded magic "64" integer instead. This is a smart approach. Thanks for info on your work. --- Ciao Romano
