Hi, HAProxy can support as many backend as you need, and as many servers as well. As you said, health check could take some CPU ressources, but depends on what does your architecture look likes, there may be advatange to configure HAProxy to use several process and let the kernel bind them on different CPUs. One key point as well is the healthcheck frequency..
