First of all, please don't reply to different sub-threads in one post, this makes following the discussion much harder and is damaging your cause.

Secondly, it's unlikely that the speed of the regex-engine matters much if combined with the overhead to read those amounts of data. Processing data in RAM is now many magnitudes faster than file-systems.

Benchmarking the whole workflow might give you a new perspective.
