a pretty strange behaviour, when downloading rancher-system-agent multiple times (from the same host, for testing purposes), the download speed sometimes is like 80MB/s, sometimes like 300kB /s, on local network, external load balancer with tls termination and stick on source IP enabled, so the traffic should be directed to the same upstream cluster member. Would it be caused by nginx ingress on upstream cluster or something else possibly? any pointers how to debug this?
