---++ Introduction

This report compares the performance of an unclustered Rational
Requirements Composer version 4.0.6 deployment to the previous 4.0.5
release. The test objective is achieved in three steps:

   * Run version 4.0.5 with standard 1.5 -hour test using 400 concurrent users.
   * Run version 4.0.6 with standard 1.5 -hour test using 400 concurrent users.
   * The test is run three times for each version and the resulting six tests are compared with each other. Three tests per version is used to get a more accurate picture since there are variations expected between runs.

---++ Findings

---+++ Performance goals

   * Verify that there are no performance regressions between current release and prior release with 400 concurrent users using the workload described below.  
      * The challenge we experience is that there is a high variance of execution time within a single run.  Depending on the load that the server is under in any given moment the execution time will vary considerably.  This could be avoided by testing the performance in a single user environment but the purpose of this test is to ensure performance is acceptable also when the server is under heavy load.  Using the median rather than the average when calculating the execution times within each test run will lessen the impact of a few slow running performance numbers.  
      * When comparing the three old runs with the three new runs we use the average of the three runs.  Because of the difference in execution times of pages between runs, as can be observed in the charts below, a margin of error of 10% is generally tolerated although faster running pages typically have a higher margin of errors (larger variation between runs). 

---+++ Findings

   * The RPT report shows similar response times for 4.0.6 and 4.0.5.       
   * Comparing nmon data for both 4.0.6 and 4.0.5 show similar CPU, memory and disk utilization on application servers and database server. 

---++ Topology

The topology under test is based on [[https://jazz.net/library/article/820#Enterprise_Distributed_Linux__DB2][Standard Topology (E1) Enterprise - Distributed / Linux / DB2.]]

---++Methodology

Rational Performance Tester was used to simulate the workload created using the
web client. Each user completed a random use case from a set of
available use cases. A Rational Performance Tester script is created for
 each use case. The scripts are organized by pages and each page
represents a user action.

Based on real customer use, the test scenario provides a ratio of 70% reads
and 30% writes. The users completed use cases at a rate of 30 pages per
hour per user. Each performance test runs for 90 minutes after all of
the users are activated in the system.

---++++Response time comparison

The median response time provided more even results than the average
response time. The nature of the high variance between tests where
 some tasks at time takes a longer time to run, such as when the server
is under heavy load, makes the average response time less
predictive. Both the median and average values are included in the
 following tables and charts for comparison.

In the repository that contained 240,000 artifacts with 400 concurrent
users, no obvious regression was shown when comparing response times
between runs.

The numbers in the following charts include all of the pages for all of the scripts that ran.

*Garbage collection*

Verbose garbage collection is enable to create the GC logs.  The GC logs shows very little variation between runs.  There is also no discernible difference between versions .  Below is one example of the output from the GC log for each application.

*RM*
   * Observation: The graph looks the same in 4.0.5 and 4.0.6.  

<img src="%ATTACHURLPATH%/RM_gc.png" width="70%" height="70%" />

*JTS*
   * Observation: The graph looks the same in 4.0.5 and 4.0.6. The high frequency of collections is normal behavior for JTS.
