Hi Thierry,
On the speed center you can compare 32 bits and 64 bits linux VMs:
http://squeak.org/codespeed/
Normally Pharo 64 should be overall slightly slower than Pharo 32 because
70% of the memory is used for pointers, implying twice more data to process
by the processor for pointer operations
Has anybody seen performance differences between the 32bits and the 64bits
versions of Pharo 6 ?
I'm seeing a speedup greater than 2 on some intensive numerical code.
Note that, on that code, Pharo 64bits is slower than R, by around 30%. The
code overall is memory bound.
