Enhancement request: increase lwIP buffers #2050

Closed obdevel closed 5 months ago

obdevel commented 7 months ago

Re our discussion at https://github.com/earlephilhower/arduino-pico/issues/2032 and my experiments with high throughput TCP and UDP traffic.

I have memory to spare but I can't currently use it for larger IP stack buffers.

It would be very useful to have an option for larger lwIP buffers, maybe 32KB and 64KB. I think this would require multiple builds of libpico.a, etc, and a new menu option, with the current 16KB being the default.

I can rebuild libpico.a as you suggested, but this isn't a viable solution for less technical users.

Thanks.

Did you increase the buffers and have it correct the timeout problem? I'm not sure it's the actual buffers vs. some other config option for LWIP...
