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 Operations/Second	Latency milliseconds
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.

#clients	Throughput Operations/Second	Latency milliseconds
16	1,000	15.95

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.

#clients	Throughput Operations/Second	Latency milliseconds
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%

LDAP Operation	#clients	Throughput Operations/Second	Latency milliseconds
Search	650	188,832	3.86
Bind	300	87,159	1.08
Modify	50	14,528	12

And finally, the:
