Looking at the code, I'd say `looking-back' is only slow if GREEDY is t
in which case the start of the match may be before LIMIT anyhow. So I
don't see how providing a LIMIT would help too much, or is
`re-search-backward' already slow without LIMIT? If so, then its own
documentation should tell so, too.
Bye,
