Hi Cip
Cool to see you trying the 64 bits :)
Your feedback and cases are really nice for Pharo.

Hi all,
I'm very happy to see that the 64 bit Pharo vm is progressing.
I've even managed to get a ~6.85 GB heap allocated (see
http://bit.ly/2lbp8n6).
This is great!
There seems however to be a small problem with the #shallowCopy message,
which is 2.63 times slower on the 64bit VM (image/vm details bellow).
The bench that I used is a simple random graph analysis tool that is
intended to do a lot of random memory accesses on big heaps, which is
accessible at http://www.smalltalkhub.com/>#!/~CipT/PlugMC
In this case I expect the execution time to be dominated by the Set
implementation (which is the case with pharo 5 -- see
http://bit.ly/2lbzJhd), and not by the array copy (see
http://>bit.ly/2kvbqvy).
Is this a 64bit limitation, or only a feature "not yet available" ?
Where can I access the latests versions of 64 bit pharo image and vm ?
