I'm using 64bit OS for quite some time (aka years) and consider it's > good sign of some technology to help me avoding fiddling with 32bit > setup. > > Yeap no doubt there, 64 bit programming languages are pretty much the standard. I am definitely a supporter of moving to 64 bit and from the looks of it , maybe I should give 64 bit pharo a try myself, I thought it was not quite ready yet. Glad I am wrong.

I am coming from common lisp which was not very different. But then there are always pros and cons with every choice and nonetheless coding in pharo is still a joy for me :) " I never heard of this disadvantage of 64 bits before. Are you basically saing you can't run multiple instances of a 64-bit VM/Image on a multicore machine? Can you elaborate? Joachim " Yeah I should have been more clear, no I am not saying that 64-bit VM cannot do this. I was talking about multiple 32 bit pharo instances against a single 64 bit pharo instance. A unfair comparison but I was just trying to make a point. This ability of multiple instances running on multiple cores is not even a VM feature, its just normal process handling of the OS. The OS assign each process to a different core to take better advantage of the processing power of the CPU.
