> 把时间分辨率从us变成ns有什么特殊的考虑吗？是不是和要解决的问题无关？ 将时间分辨率从us变成ns是为了解决高qps情况下，因为取整interval精度不够的问题，导致压测qps不准问题。举例说明，例如我们设置req_rate为510000，要是使用us，计算出来的interval = 1 us，要是忽略发送请求的时间(理想情况)，则最终的qps是1000000。要是使用ns，计算出来的interval是1960ns，忽略发送请求时间，则最终qps为510204，更为准确。 -- This is an automated message from the Apache Git Service.
