Dear Clojure/Java Experts, Earlier today I posted a question to the Immutant google group asking them a question about large numbers of concurrent websocket connections and their server. A member of the group kindly responded with a link ( https://github.com/ptaoussanis/clojure-web-server-benchmarks) to some fairly recent benchmarks that included a number of Clojure/Java servers. After looking at the numbers in the benchmark, I was a little disappointed to see that they were only serving 60K connections as compared to other solutions like Erlang which seem to be capable of 1-2+ million connections on similar hardware. The difference on the surface seems dramatic, and I was wondering if someone could help clarify the numbers for me. It makes me wounder if there is a JVM solution that can even meet these numbers half way, or if I'm missing something? Many Thanks! --Nick
####### Discussion from the Immutant Google group ###################### All, I'm a new Clojure developer, and I'm looking for a webserver that can handle a large number of concurrent websocket connections. I understand that this question is a little/very vague, and is dependent on many factors like the OS, it's Kernal, amount of RAM in the system, etc. However, there are a number of generalized claims out there, and I was wondering if anyone has done any basic testing/benchmarking with Immutant/Undertow? Examples: - http://www.http-kit.org/600k-concurrent-connection-http-kit.html - http://highscalability.com/blog/2013/5/13/the-secret-to-10-million-concurrent-connections-the-kernel-i.html - https://en.wikipedia.org/wiki/C10k_problem - https://vimeo.com/44312354 - And so on ... Thanks! --Nick -------------------------------------------------------------------------------------------------- Hi Nick, Here are some fairly recent benchmarks that are relevant: https://github.com/ptaoussanis/clojure-web-server-benchmarks --Sven ------------------------------------------------------------------------------------------------- -- You received this message because you are subscribed to the Google Groups "Clojure" group.
