Cache Entries

This section in perfdump shows the number of current cache entries and the maximum number of cache entries. In the Admin Console the current cache entries are shown as Total Cache Hits. A single cache entry represents a single IP address or DNS name lookup. The cache should be as large as the maximum number of clients that access your web site concurrently. Note that setting the cache size too high wastes memory and degrades performance.
