[pypy-dev] trying out STM for some numbers on more cores

[Davide Del Vento]

Hi Wim,

Thanks for posting your numbers. I think they are interesting and the 
11x speedup for 16 threads is not bad, however the overhead of STM is 
still too high compared to PyPy. Maybe you need also a larger dataset, 
besides a longer time?

I think for this purpose you need the best timing, not the average, 
especially if you are using a desktop/laptop. The best timing is 
something that happened and therefore "can happen". The average is 
affected by a variety of other things which may be running on your 
machine, which are better left out for this purpose (it's interesting to 
study them in order to see if one can eliminate them on a production 
environment, but that's a completely different job).

Cheers,
Davide
