I'm looking at introducing a loadbalancer to my existing site infrastructure to help with traffic growth and provide a level of failure protection.

The site I am running uses SSL certificates for the login section and I will need to continue with this functionality. The backend servers will need to be aware of the originating IP address so I can't use the TCP loadbalancing function and will need the SSL terminated on the loadbalancer so I can insert a

X-Forwarded-For

Header. I have seen a couple of ways of implementing the SSL decryption functionality one using stunnel and the other using Pound. I've been looking around however I am not sure what the pros/cons are of using one over the other. Does anyone have any experience in this and offer their recommendation?

Thanks

I currently have a site running on an Nginx platform with PHP-FPM and APC. It is performing very well with the tests I have been trying.

I would now like to add failover functionality and can't afford a hardware loadbalancer so was looking at using HAProxy.

This is more a theoretical question however will the two Nginx servers will be able to serve more pages than HAProxy and mean that HAProxy becomes a potential bottleneck.
