Highly efficient client for Pixelflut: Faster than sturmflut! (In some benchmarks at least)

Can currently only send a single picture though.


The following benchmark was run on a max-spec X280 against version d4c574b.

I could not figure out what the performance bottleneck is, but it doesn’t seem to be CPU limited, as turbo-boost doesn’t kick in.

To reproduce, run the following commands in separate shells:

iperf -s -p 1337
go run main.go -image benchmark/test.png -connection 10

55 Gbps on average! 🌊🌊🌊

sturmflut managed to get 48 Gpbs throughput on this system.

Hint: Benchmarking throughput against the pixelnuke server is pointless, as performance is then CPU-limited to ~1 Gbps by the server. Using iperf removes the server limitation. This also means that these metrics of several Gbps are far higher than realworld scenarios.
