| Commit Comment: | Overhaul the thread-pool herding code. NB: Changes to parameter defaults & units included in this commit! I tried to apply some queuing theory to this problem and as much as I admire Agner Krarup Erlang, his math isn't much help when you don't know any of the relevant metrics for your queue. Instead I took a much simpler approach: "If we fail to get a thread, we probably need more threads", and have rewritten the herder to to react faster and more reliably to such events. I went over the parameters for thread-pools and normalized timeouts to seconds rather than milliseconds (beware!) and polished descriptions etc. |
