req := &mystruct{}
json.NewDecoder(r.Body).Decode(req)We've instrument the above code block and reading request body bytes is taking very long i.e., upto 5 secs sometimes reaching upto 20 seconds at the throughput of ~4-5K RPM The Request Body Size Metrics are as follows Average: 73190 Bytes 90th percentile: 170862 Bytes 99th percentile: 467638 Bytes Tried ioutil.ReadAll too. But, the read time is same. We're not sure why it's so very slow on production with HIGH BANDWIDTH Network line. Also, there are 5% of errors in this API with following errors while decoding json data 1. unexpected EOF 2. Error in decoding request: read tcp 127.0.0.1:8080->127.0.0.1:48896: i/o timeout We're using Kubernetes with Istio 1.0.5 on GCP. These errors are probably from Envoy Sidecar, but since the Envoy acts as a reverse proxy, not sure why we can get EOF or Timeout Errors since end user connection terminates at proxy itself. -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
