Can I increase the UDP receive buffer?

[sdtechhouse]

I have a project that receives UDP packets EXTREMELY fast.

I am using the ESP32-GATEWAY. I need to receive roughly 128 packets at the exact same micro-second.

Currently, I have near perfect performance up to around 32 packets, then packets start to drop pretty quickly after that.

I assume there is a way to increase the number of receive buffers, but my google-fu has failed me.

How can I increase the throughput for receive?

Thanks in advance.

I should add, that I'm using arduino.
