This looks good 🙂 Would it be possible to estimate the compressed size if some compression method is enabled? Or at least, display a tooltip when compression is enabled to indicate that the actual bandwidth used is lower than the estimated bandwidth. |

Excellent work! 🥇 This is a much needed feature. See my comment on units (nothing super important, but maybe something to be fixed before final release).
Another thing, any particular reason not to have the profiling functions in it's own class? Just wondering, I think it's fine this way too given it's few lines for now, but I would have probably split it.
Not a blocker though, refactoring could in case be done at a later time when/if we expand on that.

At the cost of sounding pedantic, I think if we divide by 1024 we should use KiB/MiB/GiB (standard binary prefix), or divide by 1000 if we want to keep KB(kB actually)/MB/GB . See man(7) units and ISO 80000-1

Can't we just use String::humanize_size() here? 🙂

well, I didn't even know we had that function... still, the same considerations apply to that function I guess, which for now is using custom binary prefix 🤢

We could change that in a later PR 🙂 It's currently not exposed to GDScript, so that won't break compatibility to my knowledge.

@Faless I agree, it started with a couple of lines in a couple of methods but it eventually grew quite a bit. I will be making a new PR (probably after 3.2) with some UI improvements, so I will take the chance to split the code into its own class.
@Calinou I checked String::humanize_size() while working on the PR but it uses "Bytes" which was too long for the fields I was using. I can do the change to KiB, MiB, etc. in place. unless you prefer to add some options to humanize_size and keep it centralized (note that the memory-related performance counters also use a custom "humanize" code which I copied for my use case)

@JFonS I see, I guess we could change "Bytes" to "B" in the future as well.

Should be ready to merge once CI passes. |

Very nice! Would be cool to have it work with active TCP Sockets (StreamPeerTCP) as well |
This PR adds a new tab in the debugger panel that allows for some basic network profiling. It contains a list of all the nodes that communicate over the multiplayer API and, for each one, some counters on the amount of incoming and outgoing network interactions.
It also features a bandwidth meter that displays the total bandwidth usage at any given moment (computed using the size of the packets sent in the last second).
