skynet

I don't know about ASP.NET Core, but I couldn't get .NET Core to work on my Mac. I installed the "official PKG." I then ran `dotnet restore` for a project I was trying to run (https://github.com/atemerev/skynet). It downloaded a couple hundred packages, then failed with an error like, "there is no run-time assembly compatible with osx.10.9-x64." I guess it requires a newer version of OS X, but neglects to check at install time. I continue to use Mono and Xamarin Studio, although I'm stuck on an old version of Xamarin for now because I'm using Mavericks. At some point, I'd like to try OmniSharp with Emacs.

This is a joke, ok take this C++ version that takes 0 time to finish: https://github.com/atemerev/skynet/pull/26#issuecomment-1845...

Just tune the VM: https://github.com/atemerev/skynet/issues/33 and speed doubles :)

Just to drive the whole "this comparison is misleading" point further: https://github.com/atemerev/skynet/pull/23 Lwt is a cooperative multi-threading library with a particular semantic: A task that doesn't block doesn't even yield, it returns directly. Yes, it's comparing apple to oranges.

This kind of benchmark can show off what v8 is capable of (when used with a library that has been carefully tuned for performance) Code is pretty-much copy pasted from .NET Async version with bluebird promises instead of Tasks. Ends up being almost 2 times faster: https://github.com/atemerev/skynet/pull/16 (Only 50% faster if we return Promise.resolve(num) though)

there is a major flaw in the erlang version which causes unnecessary list allocation and garbage collection multiplied by 1 million times. I would try to replace lists:seq(0,9) with a tail recursion. Even that it's a small list of 10 integers, it is still created 1 million times. https://github.com/atemerev/skynet/blob/master/erlang/skynet... EDIT: it seems that list:seq overhead is insignificant - so it doesn't matter, maybe erlang compiler already optimizing it. I even inlined the calls to spawn - it still the same result. But I found another problem: it seems that some processes are stuck - so if you run benchmark the 3rd time - yo get out of processes. EDIT2: Note, that unlike other solutions. Erlang has process isolation, i.e. if there is a panic in one of your goroutines - your entire server will crash, but if there is an exceptio

No? In the scala code the timer is started and Actors are created. No warmup anywhere. https://github.com/atemerev/skynet/blob/master/scala/src/mai...

Probably not entirely, Erlang's lightweight processes have their own private heap (~1.8KB by default on a 64b system), a process dictionary and likely more control structures, and the language is mainly interpreted. A 4x different in performance may be on the high side (idk), but I wouldn't expect erlang processes to be quite as fast to spawn as goroutines. edit: and the erlang bench allocates a bunch of lists on startup: https://github.com/atemerev/skynet/blob/master/erlang/skynet... `lists:seq()` will allocate a 10-elements linked list, considering this is called recursively and concurrently it might contribute to the issue (or not)
