What does the cachesize option in slapd.conf refer to?

The cachesize option in slapd.conf specifically refers to the number of entries that the LDAP server will cache in memory. This setting is critical for performance optimization, as it allows the server to retain frequently accessed directory entries, thereby reducing the need to read from disk storage constantly. By caching entries, the server can respond more quickly to queries that access these entries, improving overall response times for client requests.

When configuring cachesize, it's important to choose a value that balances between memory consumption and the number of entries that are likely to be requested. A well-tuned cachesize can lead to reduced latency and enhanced throughput in directory services.

In contrast, the other options do not accurately reflect the meaning of cachesize. For example, the size of the cache in bytes or bits refers to the physical memory allocation, while a minimum cache size does not represent the primary function of optimally caching directory entries. The focus of cachesize is solely on the count of stored entries to improve performance.
