+# Introduction
+PeakEwmaLoadBalance is designed to converge quickly when encountering slow endpoints.
+
+It is quick to react to latency spikes recovering only cautiously.Peak EWMA takes history into account,so that slow behavior is penalized relative to the supplied `decayTime`.
+
+if there are multiple invokers and the same cost,then randomly called,which doesn't care about weight.
+
+Inspiration drawn from:

+# 简介
+PeakEwmaLoadBalance 旨在在遇到慢速端点时快速收敛。
+
+它对延迟峰值反应很快，只是谨慎地恢复。峰值 EWMA 会考虑历史，因此相对于提供的“decayTime”，缓慢的行为会受到惩罚。
+
+如果有多个调用者且成本相同，则随机调用，不关心权重。
