costs much cpu resource & time

[Ru7z]

Thanks for build this commonregex and convenient to our works，but i still have a question.
Why it costs too much time?Also my cpu temperature rise rapidly.(the length of my content is 105851 bytes)

Because these are fairly complex regular expressions the space you have to search to check whether any of the patterns match expands pretty rapidly. To help mitigate this I would use only the regular expressions that you need for your project, as the default option runs the entire set.

@ru1996 I'm curious if you have a specific example of some strings that cause this performance issue.

I also have been suffering in certain cases over 30s to evaluate a particular string for a regex pattern. Most cases, though, it finishes in a millisecond. For instance, strings with too many periods. .................................................................................................................. seems to cause the links URL pattern to take too long to evaluate.
