Thread: Provision of cluster

I noticed that there is great fall in the packed of my site on server. I do not identifying problem behind this. So I want to know about provisioning of cluster and balancing of shared cache. Any help will be appreciated.

The effect of this is every machine conserves its own independent cache, so that cached content is isolated across devices. If every question is separated to random machine, based on nature of traffic, effectual cache miss rate can be increased proportionally.

If resolvers are not precondition adequately and can’t keep up with load, this has negative impact on presentation. Packets get dropped and require to be retransmitted; name server requests must be queued. All factors include to delays. Thus, it's important for DNS resolvers to be precondition for high-volume input or output. This has handling probable DoS attacks, for which only capable solution is to over-provision with many machines.
