这不太可能严重影响性能，但是仍然会使基准测试结果产生偏差。
This is likely not a major performance hit, but it is still less than ideal to have happen in the middle of your benchmark.
标准偏差总是不可能度量的（微基准测试的典型情况）。
The standard deviations were always impossible to measure (typical of microbenchmarks).
此时识破他人的诀窍就是建立他的行为“基准线”，然后寻找偏差。
The trick is to establish what a person's "baseline" behaviour is, and then look for deviations.
