  1. Performance of New Servers @ the ACL Cesar Cavazos Accounting Information Technology (AIT)

  2. Introduction / Problem Description Background Information Possible Solutions Solution Chosen Testing / Analysis Future Work / Conclusion Agenda

  3. Large Number of Students Problems with old servers New Servers 18 new Poweredge 2650 servers 3.2 Ghz 4 Gigs of Ram Help CS Department Problem Description

  4. Dr Baker, Dr. Camden, Alberto Alonso Always had the interest in testing servers Limited experience working with servers Performance is a way too broad test Network bandwidth testing Other testing done Background Information

  5. Different tools out there Silkperformer LoadRunner TestStudio WCAT JMeter Cost of each testing tool Limitations Possible Solutions

  6. Use JMeter to test performance Java Application Simulate Heavy Load on Server Performance of Static and Dynamic Resources FTP Testing Easy to use GUI Graphical Analysis of Results Solution to Problem

  7. JMeter Interface

  8. Generating Testing Files

  9. Testing Website

  10. Uploading Data to Server

  11. Checking for Errors

  12. Testing Different Combinations

  13. Results of Project

  14. Software installed preventing more than 100 connections NFS (Network File System) crashed before webserver. (150 connections) Currently running NFS version 2 Many limitations compared to version 3 In the process of being installed Lab Administrator surprised about NFS acting as a bottleneck Results Analysis

  15. Be able to run JMeter as a Webapp using Tomcat. Test the SFTP server (when JMeter implements that option) Test the servers when they install NFS version 3 and check performance Future Work

  16. There are many limiting factors involved Jmeter itself Fact that it is a single computer No tool can really simulate ‘x’ number of different users from one computer NFS Protocol Conclusion

  17. Questions?
