0: Use SSD.
1: Use recent MMK, as that tends to work better than all but recent 
MMS. And use SSD.
2: Use MMK (or MMS) logging, and set up build parallelism, if you have 
the cores and the HDD spindles. And use SSD.
3: Use SSD. SSD. SSD. SSD. SSD. SSD. SSD. SSD. SSD. Did I mention using SSD?
4: If you're on HDD, use SSD. If you can't use SSD, don't saturate 
glacial HDD spindles. And use SSD.
5: INSTALL and parallelism helps mask part of the glacial HDD speeds, 
where SSD is massively faster than HDD.
6: I'd suggest using SSD here, too. Too many OpenVMS systems are still 
using HDD.
