Analyse performance with public test servers

[EdJoPaTo]

Public test servers like https://test.mosquitto.org are full of stuff. This is a good environment to do performance tests of mqttui.

cargo-flamegraph comes in mind first.

Irrevelevant and anecdotal but myself and a bunch of people working with me put upwards of a million datapoints every minute through MQTTUI hours on end and it is really solid performance. Nobody has reported crashes, lag spikes, or UI slowdowns. Thanks for making a great app!

It’s always great to hear positive feedback. Thanks @jr1221! 😌

One way to make it hang/crash is trying to delete all retained messages on a large hierarchy, e.g. test.mosquitto.org, on the first line (the sub-hierarchy that starts with /) hit delete, enter.
Otherwise it's a very solid piece. Thanks a bunch!
