At least for the last case, Perl has an optimized version:

$query =~ tr[ ][]s;

and it should be faster or at least as fast as the s/// version. Another version to try would be s/\s+/ /g - there is no need to use the counting variant of {2,}, and skipping might be slower than just writing the output "replacement".

`$query =~ tr[ \n\t\r\f][ ]s;` turns out to be a lot faster than any s/// variant. That change moves this line from #4 badness to #28 badness. Still having trouble with the floats, though.	[reply] [d/l]
