djs memory usage in bun
hi, I’ve been running our test discord bot on bun to try it out (some websocket issues have been fixed recently) and it runs without issue, which is great! But the memory usage is a lot higher, with this bot in 22 servers using 120mb (as opposed to about 70mb on node), which is weird because I would expect it to use less
Of course I asked in the Bun server first, and I was told that v8’s garbage collector is much more aggressive than jsc’s, implying that there is some leaky code in djs. Anyone know or aware of anything about this?

- What's your exact discord.js
npm list discord.js and node node -v version?
- Not a discord.js issue? Check out #other-js-ts.

Afaik, memory consumption is different for each bots, no matter how large or small the bot's codebase can be.
But also, some intents plays a role in memory consumption too.
I know, but this is the exact same bot, code, configuration and everything. Only difference is runtime
and I was told that v8’s garbage collector is much more aggressive than jsc’s, implying that there is some leaky code in djs.How does this imply one thing over the other? It just means the GC runs differently which has nothing to do with userland code
sorry I was paraphrasing more lightly
they did say outright that there were memory leaks
I’m not saying I immediately believe them
but I’m curious whether you think this is plausible or something different
sorry but no one can just "say" that without looking at an inspector
I don't think this is the case
The GC running more lax than the one from v8 already says a lot why it uses more memory, it keeps things in memory longer or takes a longer time to remove references
Thus your memory usage is higher, but it should be stable regardless
okay I see
yeah I only took what they claimed with a grain of salt because they very clearly don’t like djs for whatever reason
I might look into it some more idk
thanks for your help
