Re^2: SUBSTR OR REGEX: WHICH WILL YOU FAVOUR?

Recently I found simple regexp $x =~ /Something/ is just 5%-10% slower than index (on small inputs)

I actually can't see reason why perl won't recognize /Something/ as something that can be replaced by index() at compile time

And 10% is just implementation overhead.

In my benchmarks regexes are normally faster, see Re^2: How Index function works?? ff. Cheers Rolf ( addicted to the Perl Programming Language)	[reply]
