Hi everybody,

I have just ordered four SuperMicro servers with quad core Xeon CPU and 36 Gb RAM to use in a geographically redundant setup behind a load balancing cluster. We are using this configuration already, but with older servers that need to be replaced. Unbound is doing a great job already, but what we really need to keep our customers happy is a massive cache.

So, what are your suggestions for cache size settings with 36 Gb RAM? I think that it would be resonable to let Unbound use 32 Gb so the servers have plenty of room to breathe.
