Hello,
Akka version is 2.5.26 and Play is 2.7.3.
Following is a sample server that demonstrates an issue I’m having:object Test extends App{ val app = GuiceApplicationBuilder(configuration = Configuration.apply("play.server.websocket.frame.maxLength" -> 11 * 1024 * 1024)).build val routes: PartialFunction[RequestHeader, Handler] = { case GET(p"/test_pressure") => WebSocket.accept[play.api.http.websocket.Message, play.api.http.websocket.Message] { request => { Flow.fromSinkAndSource(Sink.foreach(in => { println("got message") }), Source.maybe) } } } val config = ServerConfig( rootDir = new File(""), port = Some(0), sslPort = None, address = "127.0.0.1", mode = Mode.Test, properties = System.getProperties, configuration = app.configuration ) val server = AkkaHttpServer.fromRouterWithComponents(config)(_ => routes) println("port = " + server.httpPort.get) }
A client connects to this server and sends 100 websocket messages, 10MB in size each (1GB total) as fast as possible.
I’m starting the server in 2 configurations:
- scalaVersion := “2.12.10” in build.sbt
- scalaVersion := “2.13.1” in build.sbt
This is the only difference between the two tests.
The issue is that in Scala 2.12.10 the test takes 6 seconds to complete, whereas in Scala 2.13.1 the same test takes 22 seconds.
Any idea what would make such a huge difference?
