# Docker only lags 5% in performance while paired with HAProxy makes our bidders 50% slower, any clue why?

More details besides README on GitHub. Our bidders use persistent connections, we configured HAProxy to use **http-keep-alive** , without **http-keep-alive** it runs even slower. We **disabled docker mesh routing** and added HAProxy due to mesh dropping connections to our bidders . Btw, **Traefik** proxy runs even slower then **HAProxy**. Here are the numbers on my machine

- **22K QPS** single bidder response outside of docker

- **20K QPS** single bidder response in docker

- **5K QPS** with **HAProxy** + 1 bidder in docker , **HAProxy** is part of swarm but mesh routing to **HAProxy** is disabled

- **2.5K QPS** with **Traefik** proxy with 1 bidder behind proxy , swarm mesh is disabled , sticky session in traefik enabled

Tested **HAProxy** outside of docker talking directly to bidder running outside of docker too - **7K QPS**

**QPS** - Queries Per Second

The main question is **http-keep-alive** is it for both connections to HAProxy and backend sockets where HAProxy re-routes requests ? If **http-keep-alive** is only for the front-end then I guess I know why it’s so slow .
