Aikar f827e93edf Improve default thread counts for DataFix BootStrap
Spigot capped it to 2 threads. This bumps it back up to do
maxcores -2 with a max cap of 6.

A typical 4C8T system can use 6 threads and be done in 6 seconds.

Server owners can use system property to override, but this
improves the default.
