ODSEE 7.0/11g - Degraded Group Search Performance As Compared To 6.3.1 (Doc ID 1301706.1)

Last updated on JULY 23, 2019

Applies to:

Oracle Directory Server Enterprise Edition - Version 7.0 and later
Information in this document applies to any platform.


When comparing group search performance of Directory Server 7.0 or Directory Server with that of 6.3.1 it was observed that
the number of operations per second were greater on ODSEE 6.3.1. Why?

 The following versions were used:
(a) OS: Linux dd880c42n1 2.6.9-89.0.2.EL.msdw.1largesmp #1 SMP Fri Jun 12 15:15:13 EDT 2009 x86_64
(b) Sun-Directory-Server/7.0_TN_CUMULATIVE_FIXES_1 B2010.0805.0549 (64-bit)
(c) Sun-Java(tm)-System-Directory/6.3.1_LK_6737227_6778960 B2009.0807.0930 (32-bit)
(d) SLAMD version: Version 2.0.0-alpha1

Cache sizes for tests against both the servers are as follows:
db-cache-size: 100 MB
user suffix entry-cache-size: 100 MB
Group suffix entry-cache-size: 600 MB

Both servers are running on the same hardware when the tests were conducted to eliminate any possible deviation.

The same SLAMD test was ran to search the uniquemember attribute for all sets of users (runtime: 1 hour).

The snippet of 6.3.1 and 7.0 search performance results are as follows:
6.3.1: Average Search/sec: 1907.295
7.0 - Average Search/sec: 298.765

These tests have been run more than once to confirm that results are consistent.
