John McKintosh measured it, I haven't yet profiled the VM
seriously. I've noticed that opening a large Morphic explorer seems to
be spending 50% of it's time creating points, this is my
interpretation of a Squeak profile. I've also read through the Slang
code for new.

It's enough empirical evidence for me to act.
