Bumping this too. What was the context for this change? I don’t see any JIRA tickets linked in the commits <https://github.com/clojure/core.async/compare/07e70e47a0d2f3f6b606fe2ed3a993b83cf2c29f...503b597a46a49f7d86cfb9afbe1d92798de8e2fa> with a rationale for why 8 was picked as the thread pool size. This has the potential for breaking or reducing efficiency for apps that were relying on the 42 + 2 * cores behaviour. I’m happy that this is now configurable, but puzzled as to why the default wasn’t kept as 42 + 2 * cores?
Also, because this needs to be passed as a java property, if we want our applications to be able to handle differing core counts (e.g. running on heterogenous servers) it seems like we will need to write a bash script to calculate our threadpool size before starting up. Perhaps I’m missing something really obvious here, if so, please let me know :) Tim Ewald, can you help with this?
