Oracle Internet Directory 11g Benchmark on SPARC T5

SUMMARY

System Under Test (SUT)     Oracle's SPARC T5-2 server
Software     Oracle Internet Directory 11gR1-PS6
Target Load     50 million user entries
Reference URL     OID/T5 benchmark white paper

Oracle Internet Directory (OID) is an LDAP v3 Directory Server that has multi-threaded, multi-process, multi-instance process architecture with Oracle database as the directory store.


BENCHMARK WORKLOAD DESCRIPTION

Five test scenarios were executed in this benchmark - each test scenario performing a different type of LDAP operation. The key metrics are throughput -- the number of operations completed per second, and latency -- the time it took in milliseconds to complete an operation.

TEST SCENARIOS & RESULTS

1. LDAP Search operation : search for and retrieve specific entries from the directory

In this test scenario, each LDAP search operation matches a single unique entry. Each Search operation results in the lookup of an entry in such a way that no client looks up the same entry twice and no two clients lookup the same entry, and all entries are looked-up randomly.

#clients Throughput

1,000 944,624 1.05

2. LDAP Add operation : add entries, their object classes, attributes and values to the directory

In this test scenario, 16 concurrent LDAP clients added 500,000 entries of object class InetOrgPerson with 21 attributes to the directory.

3. LDAP Compare operation : compare a given attribute value to the attribute value in a directory entry

In this test scenario, userpassword attribute was compared. That is, each LDAP Compare operation matches user password of a user.

#clients Throughput
Operations/Second
Latency
milliseconds
1,000 594,426 1.68

4. LDAP Modify operation : add, delete or replace attributes for entries

In this test scenario, 50 concurrent LDAP clients updated a unique entry each time and a total of 50 million entries were updated. Attribute that is being modified was not indexed

#clients Throughput
Operations/Second
Latency
milliseconds
50 16,735 2.98

5. LDAP Authentication operation : authenticates the credentials of a user

In this test scenario, 1000 concurrent LDAP clients authenticated 50 million users.

1,000 305,307 3.27

BONUS: LDAP Mixed operations Test

In this test scenario, 1000 LDAP clients were used to perform LDAP Search, Bind and Modify operations concurrently.
Operation breakdown (load distribution): Search: 65%. Bind: 30%. Modify: 5%

Bind 300 87,159 1.08
Modify 50 14,528 12

And finally, the:
