AFS makes the best of multi-core architectures. Searching indexes is aligned (multi-threaded) on all the cores available on the server. With the capability to split indexes into layers and to run several reply servers in parallel for a same query, higher performance can be achieved.
AFS is designed to work on any server of x86 dual two- or four-processor dual-core type. It is certified to work on Linux RedHat, CentOS or Debian 64 bits distributions.
