Throughput
In general terms, throughput is the rate at which something can be produced, consumed or processed.
Latency
- How NOT to Measure Latency https://www.infoq.com/presentations/latency-response-time
Latency and response time are synonymous: the length of time it takes something interesting to happen.
Standard deviation does not have any meaning for a dataset that describes latency. It is not relevant.
Organizatorium
- Don't censor bad data, don't throw away data selectively.
- Never average percentiles.
- Coordinated omission.
