Is it? Smaller business usually comes with smaller applications. Most cloud and hardware vendors give you about 4GiB of RAM per core, maybe only 2 when using "CPU optimized instances", that's huge and leave plenty of space for a couple hundred MB of JITed code.

Agreed. In Java land, if I understand correctly the OpenJ9 JVM can (or at least could) beat HotSpot in memory consumption, while being slightly behind in execution times. It still sees only limited adoption. This may be just because it's seen as an 'alternative' option, less trustworthy than HotSpot, but it also seems to indicate the HotSpot developers aren't prioritising memory consumption.
