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.
Do you mind to list some?
Well the ones I care is lack for documentation or outdated documentation, lack of class method comments and lack of libraries which are the usual problems for small communities like pharo. 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.
