My Windows installation does not have virtual memory as I turned it off (I
don't need it as I have sufficient physical memory not to have it). I have
now set InnoDB buffer size to 1G for MySQL 5.6  5.7 as well as Maria DB
10.0 and 10.1. That is more than enough for my needs. The MariaDB instances
now show total allocated memory ~2.5 G (5.5. and 10.0) and  ~1.5 G (10.1).
The MySQL instances ~1.5 G.
