Is jdbc or ldap faster for basic read operations?

Question

I have a set of user data which I am try to access. Due to the way our company's employee data is set up, the information is available both through LDAP and through a table in our DB.

I was curious, for standard read operations which would generally be a higher performance query?

Answer 1

LDAP supports Extremely fast Read operations. Directories are tuned for higher read performance because the nature of the data in the directory is more commonly read than written or updated.

Answer 2

JDBC and LDAP are only protocols, they don't impact performance nearly as much as things like indexing, caching, disk speed, network latency, etc.
