And how many zones on the disk occupy? Can it make sense to put it in the / dev / shm area and run from there?
Also, NSD is really much faster in this regard (it actually sucks everything into memory).

Try NSD It stands on the root servers.
It also makes sense to speed up the disk subsystem with Flashcache and RAID10, and/or write the base to an SSD RAID.

Theoretically, if each zone is stored in a separate file, then a lot of time will be spent opening/closing the zone file. You can try to combine the files into several large ones, then the download should speed up.

Just your case.

I would put a controller with good caching (real, iron), or use Flashcache and RAID10, as suggested by @d00mko .
Also, I would still trace dstat more precisely when loading the zone, then it will be clear what to "pump", but I think this is IO.
