rtl_tcp uses a full CPU core #7

Closed OE4AMW closed 1 year ago

OE4AMW commented 4 years ago

The variant of rtl_tcp using a ringbuffer performs quite well, however, it always uses 100% of a CPU (on a raspberry pi 1, pi 4, or even on my laptop with a core i7).

I have found the same to be the case on a Raspberry Pi 4 running Raspbian.

Will be going back to the standard rtl_tcp implementation in the next update, it looks like the ring buffer patch has issues.
