Describe the bug you're experiencing

Hello,
i have a modpack with 312 mods, when i tried adding

i couldn't log into server beacause of "Paylod may not be larger than 1048576 bytes"
Then i added connectivity-1.19.2-4.6.jar to be able to join, however when loaded to world, i started experiencing a massive lag beetwen client and server, in which client was about a minute behind. after the minute it simply disconects the client

Reproducability

adding 2 mods to 312, after that connectivity, joining server, then you can see the lag between console output and client side

report it to those two mods, connectivity just allows sending larger data, one of those mods is sending massive amounts of data stalling the client
