Wrong.
When you test regex, you can see this:
this:
and this:
As you can see, green bar in upper right corner shows you steps count when parse and _execute_ regex.
This is performance info you required. This is obvious.
More steps - slower exec. So odd you can't see obvious.
Otherwise only regex gurus/creator can tell you how fast/slow is any regex. Regex is magic.
Also, just for minute, you asking in wrong place. This is squid, not regex.

If will be faster to check just ONE optimized regex like (www\.)?(facebook|google).com than the previous three?
I'm really talking about optimizing about 3000 url regexes in one huge regex because comparing each and every url to 3000 regexes is too slow.
I know using (www\.facebook\.com)|(facebook\.com)|(www\.google\.com)|(google\.com) with PCRE will produce the same optimized result as (www\.)?(facebook|google)\.com. Squid uses GnuRegex. Does GNURegex lib optimizes this as well ?
