Actually one *can* make the linux VM faster than the MacOS one on the same hardware using just the right version of GCC.
But frankly the *easiest* way of doing that is for Pharo to fund the yearly license for using the Intel Compiler and provide a one-click Intel compiler based VM.
For Intel CPUs that's a good solution, but those binaries would be really slow on AMD and VIA CPUs.

Maybe, assuming someone runs some numbers, and/or you think that intel purposely trashes performance on those machines if you use their compilers?

Also is the linux crowd 100% AMD/VIA? If it's only 20% as per the Intel CPU market share, then maybe the 80% of linux
Definitely not.
intel CPU based users would enjoy better performance versus a muddled offering in order to keep in line with the slowest 20% of the user base?
I'm not against the use of icc, but it's not a silver bullet. The question is: how much better performance can be achieved with it? Having 2% better performance for 80% of the users, while -50% performance for the rest doesn't worth it IMHO. Levente
