I’m working on a stress test script that creates WebSockets.
I don’t know why, but the creation of the web sockets breaks after around 7,600 calls to this function.
If I run the script in a docker container, I can accumulate the number of web sockets created up to 90 000, so it seems to be a host-related issue.
Regarding the resources, it’s working pretty well on each docker instance, so I’m thinking about a configuration of the compiler but I don’t know much about the capabilities yet (I’m currently digging into it)
I know that the maximum number of web socket creations is limited by the number of ports available (client-side) but I’m far from this limit it should be around 64,500.
FROM golang:1.21-alpine3.17 AS builder
FROM scratch AS final
I just changed the Dockerfile so the image is based on the Golang/Alpine image: FROM golang:1.21-alpine3.17 AS final
$ ulimit -n
Now it is working, I just have this tls handshake error, but it’s happening randomly after 18 000 to 22 000 connections despite this TLSConfig that is set to ignore some security verifications … but it’s another story.
tls: handshake message of length 2243106 bytes exceeds maximum of 65536 bytes
