Question

Recently，I performed a pressure test to dragonfly，with 283 concurrent peers Version： Dragonfly_1.0.4 Os：linux Concurrent Peers：283 Supernode：1 Result：

Average time spent in seconds / concurrency number 20 50 100 200 283
wget 2.765 10.0776 15.831 32.2331 48
p2p 26.397 27.4668 27.2166 139.387 395.339

So I got two question：

  • why dfget much slow then normal wget？
  • when concurrent peers exceeded 100，peer start to wait with a “peer should wait” INFO，am I missing something or config wrong ？

I have tested in 500 nodes k8s cluster, can not reproduce the "peer sholud wait" INFO. Can you provide config ant dfget command ?
