1. I'm surprised no one has asked you a) how many regexes there are; b) to show a few 'typical examples' of the regexes involved.

    Beyond the 5.10 trie optimisation--which also has some limitations--there are other ways of optimising the use of multiple regexes against single buffers, but they do tend to vary with the nature of the regexes involved.

  2. On the basis of what you've shown so far, it looks like this task might be effectively parallelised using threads

    However, your need to stick with 5.8.0--a time when threads were still quite flakey--means I would be reluctant to suggest that solution unless you can upgrade to at least 5.8.5--though 5.8.9 or 5.10+ would be far better.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
