Proxy selection: mod_proxy_balancer, nginx + proxy balancer, haproxy?

We launch the Rails website at http://hansard.millbanksystems.com on a special accelerator. We currently have an Apache installation with mod-proxy-balancer, which maximizes up to four mongrels running the application.

Some requests are executed rather slowly, and to prevent a situation when other requests are queued for them, we are considering proxy options that will send requests to the idler, if any.

Possible options:

  • recompiling mod_proxy_balancer for Apache as described at http://labs.reevoo.com/

  • compiling nginx with a fair proxy balancer for Solaris

  • haproxy compilation for Open Solaris (although this may not work well with SMF)

Are these reasonable options? Did we miss something obvious? We will be very grateful for your advice.

Apache is a bit of a strange beast that you can use for balancing. This is certainly capable, but he likes to use the tank for shopping.

Haproxy / Nginx is more specifically designed to work. You should get higher throughput and use fewer resources at the same time.

HAProxy offers a much richer set of load balancing features than mod_proxy_balancernginx and almost any other software out there.
