"fast" is a non-descriptive word as we try to be fast in any operation?
Maybe core.parallelIndexReading as that just describes what it
turns on/off, without second guessing its effects?

Another option is index.threads (the "index" section currently only
has one item, index.version). The value could be the same as
grep.threads or pack.threads.

(and if you're thinking about parallelizing write as well but it
should be tuned differently, then perhaps index.readThreads, but I
don't think we need to go that far)
