So, I've been tasked with shoring up a perl script that outputs all manner of information to whoever calls up the page that it is on. it pulls from a number of databases and files, parses their info, adds div tags and font tags and whatnot, and outputs it all as an HTML page.
Question: the majority of the adds and blocks of 'print' are using double quotes, not single quotes. even the final block is something like
where each of those info vars are their own little:
$info1="this is some sample stuff".$info_in."<br><br>";
My question - do you *really* get that much optimization from removing all the necessary double-quoted strings, and make them single-quoted?
