Marcelo Vanzin commented on INCUBATOR-210:
------------------------------------------

I thought so at first, but Google Translate says:

Servicecomb current performance statistics do not support the statistics of delay distribution,
which is of great importance to the service, that is, the statistics of delay distribution
like [0,200] and [200,400). The average delay may cover some problems in the system, for example,
part High latency, but masked by normal average

> Servicecomb当前性能统计不支持时延分布的统计,这个对于业务有重要意义,也就是类似[0,200),[200,400)这种时延分布的统计,平均时延可能会掩盖系统的部分问题,比如部分高延时,但是被正常平均值掩盖了
