Issue description

To preface this:

I play on a minecraft server called "Wynncraft". It's really cool, but it's not relevant here. I only thought to mention it because it might be relevant.

I get really random lag spikes that go on for a solid minute and are really annoying, so I profiled my client by following https://spark.lucko.me/docs/guides/Finding-lag-spikes
and it turns out that somehow Jade is causing lag.

Look at this spark profile (client):

https://spark.lucko.me/5iRsMfM8rE

It's profiled with ticks that take >100ms, during one of those lag spikes.

https://spark.lucko.me/h5kR7DkhIV

Here is a normal profile with no custom options where a lag spike did not occur, and jade is only taking up 1% compared to the 28% in the previous one.

All it seems to be doing is converting something to JSON. I wonder how that's causing lag. Is it writing to a file or something?

Or is maybe Jade showing up falsely because it's trying to write to my drive or something and it's getting bottlenecked?

Can you tell me the file size of config/jade/usernamecache.json?

it says 4MiB

It's filled with crap like this btw

Because of fake players generated by server

Fixed in 1.20+ but I don't have time to backport it to 1.19.4 in the next few weeks

Thank you!
