Description
sentinel集群限流的,嵌入模式。

以上是dashboard的配置,maxAllowedQps 也持久化到server。
测试结果的一些指标如下:
最大qps:200及以上,限流稳定在100左右
最大qps:100-200,限流小于100(30多,40多,。。。)
最大qps:100及以下,限流大于100(130,140.。。。。)
maxAllowedQps 在wiki中说到时为了保护嵌入模式的server,但是对集群的qps也有一定的影响。不是很明白,源码部分大致看了下,没发现有特殊影响。
请帮忙解答下

Research direction
Start with the dashboard configuration and the wiki description of maxAllowedQps, then trace the source handling this value in embedded and cluster flow-control modes. Compare the persisted server setting with the reported QPS results. Done means explaining the discrepancy from the source or identifying a reproducible defect; no specific files or tests are named.
