Sped up seeking for files to operate on, when using options like --copies or --in, by around 20%. Benchmark showed an increase for --copies from 155 seconds to 121 seconds, and --in remote will be similar to that. For --in here, the speedup was less, 5-10% or so. (both warm cache) This commit was sponsored by Jack Hill on Patreon.

As part of the work in [[precache_logs_for_speed_with_cat-file_--buffer]],
|
|
key lookups are now done twice as fast as before.
|
|
|
|
But, limits that look up keys still do a key lookup, before the key
|
|
is looked up efficiently. Avoiding that would speed up --in etc, probably
|
|
another 1.5x-2x speedup when such limits are used. What that optimisation
|
|
needs is a way to tell if the current limit needs the key or not. If it
|
|
does, then match on it after getting the key (and precaching the location
|
|
log for limits that need that), otherwise before getting the key.
