The performance of LDAP is satisfactory for most applications. The same DSA was used for all query measurements, providing a baseline for comparison. Table 1 shows the performance of a range of typical DAP and LDAP queries. As can be seen in the table, the delay introduced by LDAP is minimal. This delay could be eliminated altogether by a native DSA implementation, eliminating the intermediate encoding, decoding, and protocol translation.
Times are in milliseconds.
Table 2 shows the size of the queries and results given in Table 1. It shows that LDAP queries are substantially smaller than equivalent DAP queries. The savings are due primarily to the simplified DN and value encodings. Query sizes are also reduced by the absence of service controls in every operation. Query sizes are in bytes.
