Memory leak

[Syfaro]

Hmm... you're definitely right that there's a memory leak somewhere.

I think it has something to do with the form, but I'm not entirely sure. I'll work on figuring out what's happening.

Well, this is what's using the most memory.

This might be a limitation in Go.

so nothing we can do about it ?

I can confirm that github.com/rockneurotiko/go-tgbot has the same issue

[Syfaro]

Well, this commit will reduce memory usage, a 30MiB test file increases my memory usage by ~2MB.

That upload function is pretty much identical to mine, so I don't know what the difference could be.

I just tried it out, it is a great improvement.

If in the future anyone comes up with a better solution, I'd be happy to reopen this. Until then, I'm going to close it.
