Agree, in some case, I seem to find Cchar is really shine at 10x faster than Python from A to Z, 1000x faster than normal Swift? Not sure if there was flaw in the time measurement.<br><br>On Sunday, 9 April 2017, Rien <<a href="mailto:Rien@balancingrock.nl">Rien@balancingrock.nl</a>> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Server-side is usually UTF-8 (not always), so often you don’t really need strings.<br>
As an aside, time measurements are difficult, especially when IO is involved there may be thread switches or locks.<br>
<br>
I have written some parsers (UTF-8 based) and not yet encountered performance problems. (though faster is always better)<br>
