I'm new here so I'm sorry if this is something already covered. I spent a bit of time browsing the archive but didn't see anything obvious.
When Pharo is under load it doesn't appear to making use of all processor cores.
I'm using Pharo-1.1.1-- Latest update: #11414 with VM 4.2.1b1 under Mac OS X with a Core 2 Duo.
Attached is an image of the CPU history:
The thing to notice is that it only appears to be using a single core at any one time.
Is this a known issue?
Yes. Squeak VM using green threading model - it runs a language-side processes using single native thread.
