Local UDP packet drops reported in /proc/net/udp
dholroyd opened this issue · 4 comments
In my testing I've been seeing relatively high rates of UDP packet drops reported via /proc/net/udp. I have the same stream being received on the same machine via RIST instead of SRT, and the socket entries for that process in /proc/net/udp report no drops; I hope this shows that the problem is not down to CPU overload etc on the machine hosting the test.
I've not debugged enough yet to show this is a problem with srt-rs, rather than a problem with my own application code blocking the event loop (for example), but I wondered if this is a known issue?
It is probably a srt-rs issue--this library isn't really ready for production use--probably related to #75. I'll take a look at /proc/net/udp, could be a helpful metric.
For high bandwidth connections, it's necessary to increase receive and transmit buffers on linux:
sudo sysctl -w net.core.rmem_default=8388608
sudo sysctl -w net.core.wmem_default=8388608
This allows me to more reliably stream
Also, hopefully #102 might help with this @robertream
Considering this closed for the time being. Re-open if the issue still exists with those increased buffer sizes
