[Question]: How to optimise the memory usage for websocket client

[sdroege]

Use a profiler and check where the memory is actually used up, and then we can look at optimizing those things :)
Do you have a testcase for this that you can share btw?

[coder3101]

I profiled using instruments and found that native-tls on linux was causing too much memory allocation. I replaced it with rust-tls and now 10 times less memory is being allocated.

During profiling I also found that connect_async was the highest contributor to memory usage.

Which part?

[coder3101]

For native-tls, connect_async handshake is consuming most, also for some reason this is more prevalent incase of linux.

For rustls-tls

I see. Do you see any possibility of optimization in there? :)
