Benchmarks
While you read this sentence*, one processor core reads 320 000 000 protocol frames.
These are our own measurements of our own code. We do not publish other products' numbers: we have not measured them.
Each number is the median of three runs of a Go benchmark on the named machine, in time per operation. Fewer memory allocations mean less work for the garbage collector, and so steadier latency under load.
A micro-benchmark measures one step on a warm processor, not a whole delivery: the network, the disk and the other side add their own time. Lower is better.
Each comparison uses the fastest processor's time; the speed or frequency it rests on is given in brackets.
* An average reader reads a sentence in about three seconds (238 words a minute, Brysbaert 2019).
Protocol frames
