  1. Evaluating Web-Based Multimedia Performance on Thin-Clients and RDP Damian Clarke Michael Gonzales

  2. Background • What is a Thin-client? • A thin client is a computer or a computer program which depends heavily on some other computer to fulfill its traditional computational roles. • Less management needed as most resources are focused on the server • Traditional Uses • Low-budget, low-bandwidth, centralized environments where computing resources are limited

  3. Proposed Work • Why? • Evaluate performance of web-based multimedia on thin-clients • Multimedia types: Flash vs. HTML 5 • Evaluate Remote Desktop Protocol (RDP) vs. Sun-Ray thin client performance • Compare various scenarios of clients connected vs. native performance

  4. Thin-Client Experimental Set-up • Sun Ray Server 5.2 running on Solaris 11, 2.8Ghz, 3GB RAM • Apple Airport Express Router • Sun Ray Thin Client 2 and a 2FS • 1-2 X-Windows Remote clients for comparison purposes

  5. Measurement and Instrumentation tools • GUIMARK 2 • FPS benchmarking tool to analyze Flash and HTML 5 multimedia performance • Rendering performance to screen based on 60 fps rate • Dtrace • Integrated Solaris OS Dynamic Instrumentation Utility • Instrumentation granularity : User and kernel level software Thread-local variables, Associative arrays, Data aggregation and Speculative Tracing • Subjective evaluations • User perceived performance of thin-client performance over native performance

  6. GUIMARK Testing Types • Vector Charting Test • Stresses vector graphics of the designated application by simulating a streaming stock chart with different alpha fills

  7. GUIMARK Testing Types • Bitmap Gaming Test • Simulates a tower defense game. Uses lots of bitmap resources and animations for sprites on screen at once.

  8. GUIMARK Testing Types • Text Column Test • Tests rendering capability of various text organizations and character types

  9. GUIMARK Experimental Results (Firefox 7)

  10. GUIMARK Experimental Results (Firefox 7)

  11. GUIMARK Experimental Results (Firefox 7)

  12. Averages Frames per second

  13. Remaining Tasks • Instrumentation • DtraceScripts: To provided analysis of possible bottlenecks such as network lag, CPU and memory scheduling • Additional scenarios of thin-client web multimedia frame-rates with Sun Rays and X-session comparisons • Look at the option of varying bandwidth configurations of the router to gauge impact on performance

  14. Questions and Comments?
