To find out how many URP packets we can send, this project does the following:
- The server receives UDP packets at a given port
- The client sends tiny updates at a fixe rate (atm 100K per second)
- The server receives the datagrams, parses them to the original rust struct
- The parsed packets are send via a
tokio::sync::mpscchannel to another task for processing.
- run the server:
cd server && cargo run --release - run the client (possibly on a different machine):
cd client && ./run_many_clients.sh
The server will then display the rate and cound of packets received
Between two hosts I could achieve about 500Kpps. Increasing the client count or rate did not increase the processing rate. When starting multiple independent servers, the total processing rate did not increase either. I therefore conclude that these 500Kpps are limited by the OS or hardware. This assumption is supported by the fact, that if running on localhost, I can acheive about 700Kpps on my machine.
