AFS is by design a highly available 24/7 solution with predictable reply times which are independent from the indexed data volume and from the number of queries to handle. Whatever the number of documents and the number of queries, a fine-tuned implementation of AFS ensures average reply times from the engine below 500ms.
AFS can be upgraded easily. To increase its capacity in linear mode, it is just necessary to add resources. Several hundred millions of documents can be indexed and several millions of daily queries can be processed. AFS is used by large websites and portals with an yearly availability rate above 99.9%.
