Just wondering, does any one have any experience of using software load balancers on a linode? I am pretty sure I will never need one but I am just interested to know what software people use.

I have used pound once and it worked quite well for the project needs but I was wondering if people had used HAProxy or any other product?

If you need simple round robin then nginx works: http://wiki.nginx.org/NginxHttpUpstreamModule

Thats an interesting, looks much more performant than other solutions I have looked at.

I've been using haproxy for this. its a bit more featureful than nginx (assuming you need the features it offers). It's very performant, should have no trouble saturating a network connection.
