Packet Profiler - accurately measure remote packet bandwidth!

Small update: I’ve added additional images & updated the plugin’s destriction, as per Roblox’s new asset description features: Improved Asset Description Features [Creator Marketplace]

The chart also does not show anything for me. Tried everything but nothing seems to fix it :sad:


Have you selected a frame in the profiler?

Plugin stopped working for me too after the latest update

its working fine for me with the latest version. Are you sure there are remotes being sent from server → client? The packet profiler only logs incoming remotes, not the remotes being sent from the current run context.

The packet size counter used in this plugin has now been separated into a separate resource:

This plugin has additionally also been updated with more cleanup:

  • Remove foreman, switch tools to aftman
  • Separate PacketSizeCounter into separate package, use it as Wally dependency instead
  • Update with more descriptions of the plugin’s behavior
  • Add
  • Describe the project’s contribution & development process
incorrect information, read below.

this is essentially conjecture, but ever since adding this to my game i have had a noticeable increase in reports of server crashes. not sure how this would be triggered, and its definitely possible it has nothing to do with this resource. but use with discretion.

yeah, this module is fine. I was getting ddosed.

The plugin does not activate, i.e. run, until you first open it for the first time - meaning it should have no impact on the game until it’s opened for the first time:

Do you use Stats Service? Or just fixed data and then calculate the data with the overhead data

you can see how I calculate the data in this thread: Remote Packet Size Counter - accurately measure the amount of bytes for remotes!

  • Update RemotePacketSizeCounter dependency to v2.3.1

NOTE: please update your plugin & potential in-game modules! Despite updating the packet size counter’s version, I didn’t actually install the new version, which caused it to be at v2.1.0 this whole time.

Added the latest version to our game, but it doesn’t seem to open up the menu for me when I press ctrl+f5 everytime.
Works fine on join, but then sometimes it can disappear when dying, and pressing ctrl+f5 again doesn’t bring it back up again.

We do use a custom loadcharacter…


  • Fix in-game profiler gui disappearing upon respawn

NOTE: if you rely on custom PlayerGui cleaning behavior (e.g. destroying all screenguis upon respawn), make sure you don’t destroy PacketChart and PacketProfiler!

Hey, I just stumbled upon a documentation of the ROBLOX File Format. I’m not entirely sure if it’s accurate, but I found it on MaximumADHD’s reply and it’s also mentioned on the Wikipedia page about file signatures List of file Signature. Maybe check it out?
