Oracle LDAP Numbers Are Available

BOSTON (06/12/2000) - In our review of Lightweight Directory Access Protocol (LDAP) servers last month, we were unable to include performance test results for Oracle Corp.'s Oracle Internet Directory (OID) because of time constraints involved with the review. Since then, we have completed the performance tests.

OID's performance fell in the middle of the seven LDAP directory servers we tested. OID was slower than directory servers built by iPlanet, Innosoft and Critical Path Inc. (formerly Isocor) but was faster than products from Novell Inc., Siemens AG and Computer Associates International Inc. We rated Oracle 6 out of 10 for performance, an overall rating of 5.6 for fourth place in our rankings.

Oracle's load time was impressive, falling just behind the leaders in this performance category, iPlanet and Innosoft. Oracle's bulk-load process has two parts. First, the software converts the standard Lightweight Directory Interface File (LDIF) format into an Oracle-specific format; then it loads this format directly into OID. The conversion takes most of the time; if you could write out your data in the Oracle-specific format instead of LDIF, you'd find Oracle the fastest of all tested at bulk loading. Oracle sent a team to assist with the performance testing, and they went through four rounds of tuning, which substantially improved OID's performance from its out-of-the-box scores.

For the seven other performance test categories that included messaging, addressing and wildcard queries, OID turned in respectable, but unremarkable, performance numbers.
