Re: v8 first impressions

Just a slight update to my earlier post about the relative performance
of various VMs.

With the new back-end in place the performance of the Strongtalk VM
improves substantially. I didn't include it in my previous test,
because I honestly didn't think it was stable enough to complete a
run. Still, I gave it a try and it surprised me.

A 100 run average time with the new back-end produces an average time
of 4.36ms. That's about 3 times as fast as the VW and V8 figures.

Running with the new back-end is pretty unstable (I had to try a
couple of times to get a complete run and paste the results in a
spreadsheet without the VM crashing with an access violation), but it
does offer the prospect of substantial performance improvements.
