For the number-thirsty types, I have reworked tclbench to run on a configurable number of threads. I then ran this such that expr.bench (a small benchmark for some expr operations) was repeated 25 times. This was to test the value of the reduced lock contention. In this particular set of tests, there is *zero value* to using threads, this just compares performance on obj allocation and usage across threads.
You can see the results at:
