euler性能指标QPS的含义

https://github.com/alibaba/euler/wiki/Efficiency
请问Euler此次性能试验的指标QPS(samples trained per seconds)的含义是什么？是指每秒能做几次sampling吗？

Start with the Efficiency wiki page linked in the issue and locate the definition of QPS, shown there as “samples trained per seconds.” Clarify whether this measures sampling operations per second, and update the page so the metric's meaning is explicit; there is no test or source file mentioned.
