wu-sheng opened a new pull request #2271: Improve OAP cluster performance 
URL: https://github.com/apache/incubator-skywalking/pull/2271
 
 
   In these days tests, by my back to back works with @hanahmily , we made big progresses in
   
   1. Reduce CPU cost in low payload
   2. 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 do following changes
   1. Remove the codes about sending to L2 in every 1000 indicator rows.
   1. Make L2 send based on the timeline, send every second by default.
   1. Settings related to DataCarrier channel and buffer sizes could be set by System env.
   
   Let's see the test results.
