Fix default memory calculation to binary Megabytes.

hlg · hlg · commit b8e8cbb3dffe · 2024-11-25T17:38:05.000+01:00
For RAM sizes of 64 GB the previous calculation was hitting the range
just above 32 GB, which is unfortunate due to uncompressed object
pointers being inefficient in the range from 32 GB to around 40-50 GB
compared to compressed OOP in the range below 32 GB. Also, JVM errors
have been observed for those values.
