Large, fixed buffer size.

[macwilam]

Hi,
in lib.rs the buffer size is configured:
const BUFFER_SIZE: usize = 65_507;

I am trying to check the limit in lab testing in the number of agents I can poll with this crate and it seems that the buffer size starts to affect the memory usage.

This is not a bug and not a major issue.

However I was wondering why such a large buffer if most communication is done via UDP and limited by typical MTU anyway?

Is there a chance to make it configurable or maybe make feature flags for small (1550) and medium buffers (10000) for some jumbo frames?

Just a thought :)

Good day,

this migrated from the original crate. I agree, the buffer size should usually about 1300-1400 for the standard MTU 1500. making it configurable is a nice idea. will record into todo

I might be wrong but by using const generics it might be easily done with backwards compatibility:
// Internal buffer struct becomes generic
pub(crate) struct Buf { ... }

// Sessions become generic with defaults
pub struct SyncSession { ... }
pub struct AsyncSession { ... }

But I havent tested that.
