wu-sheng opened a new pull request #2269: [WIP] Continue to performance improvement
URL: https://github.com/apache/incubator-skywalking/pull/2269
 
 
   In these days tests, by my back to back works with @hanahmily , we made big progresses in
   1. Reduce CPU cost in low payload 
   1. Improve single node in 8U(GCP) performance to 80k telemetry per second.
   
   But we still need to work on improving performance in cluster mode and when scale out. 
   
   Right now, 3 nodes cluster has only the same performance as a single node, also scaling out from 1 to 3 doesn't make performance better.
   
   In this pull request, I try to extend the L1 buffer channel size and remove unnecessary codes which make the batch size much smaller than queue size.
