[thelist] Optimising ASP/HTML

[Andreas Wahlin]

I've just performed some extremely unscientific tests. I was wondering
how I could optimise output and rendering performance. The test was
conducted with asp and IE (because most people use that, I also did
quick checks in FF)

First I thought that it would be faster to assemble all output into one
variable and ther print it to the page

For (var i = 0; i < 100; i++)
	output += source;
Response.Write(output);

Rather than

For (var i = 0; i < 100; i++)
	Response.Write(output);


This however did not seem to be the case. 
Then I went ahead and checked rendering time of pure text vs markeup,
not surprisingly markup was slower to render, thus comparing
Sample text
Vs
<b>text</b>

The "Sample text" rendered faster. Then I thought that advanced markup,
like tables, wolud render slow than more direct, like lists. (an update
from table design to more correct/semantic/standard/cool factor divs and
list design) but this did not seem to be the case (except of course that
a list design contains less text than a table design, if you were to
count the number of characters it needs) I did not work with that
complex a table either ...

Any comments?
