Faster way to find matching patterns from external file grep -f
{patternfile} {source} in BASH

In *nix terminal (Bash) os there any other faster way to find a pattern
(or excluding them - egrep -v option) than using this:
grep -f {patternfile} {source}
Using this option is painfully slow for larger files.
