In Synedit's PaintLines is a functioin called AddHighlightToken.

At one point it copies the current token to the end of the TokenAccu. At this point a remark can be found:

    // Don't use AppendStr because it's more expensive.

Instead of using AppendStr, it implements a plain "for i := 0 to ..."
loop, copying the content byte by byte.

I am pretty sure (but would like to have that confirmed) that using "move" would be even faster?
yes I could set up a test and profile it, but maybe someone already knows how move performs vs for loops ?

Thanks in advance

A simple for loop of a few iterations is always faster than a procedure call. And afaik AppendStr created a lot more overhead.

Some years ago Move was slower than loops with a few iterations. Unless Move is now inlined, this is still true.

Every theory is grey. Only a real test gives you a clue.
