In the Tor v0.2.2.x series it was said that it was pointless to set NumCPUs to a value greater than 2. Due to poor scaling, I guess.

Is that still the case with v0.2.3.24+ ? Would NumCPUs value of 4 or 8 (on systems with that many CPU cores) actually provide any benefit over a value of 2?

It might help circuit start-up latency a little, but other crypto still isn't parallelized, so it won't help a ton. I'd like to have that happen in 0.2.4, but there are a lot of other features I want for 0.2.4 too, so we'll have to see whether it gets done in time. (The feature I want MOST for 0.2.4 is "comes out on schedule.") yrs, -- Nick
