> Getting the Most Out of Your LoadTest Machine

  eValid generates load with full fidelity by playing back scripts on
  your load generation machine with multiple parallel executing copies
  of eValid.

  To get maximum performance you'll need to make several adjustments to
  your machine.  We normally are able to run at least 100 simultaneous
  full fidelity browsers on a 500+ MHz P-III machine with 256 MB of RAM.
  Your mileage may vary; we have had up to 250 running but that is an
  exceptional situation.

  * Machine Properties.  Our baseline machine for eValid LoadTest runs
    is a P-III, 850 MHz with 512 MB of RAM, with a Video RAM of 64 MB.  
    The baseline OS is Windows 2000 with the latest service packs.

  * Virtual Memory.  You have to increase the amount of space available
    in Virtual Memory upward.  A setting of 900 MB is a good value to
    use.

  * Heap Space.  You have to adjust the amount of heap space upward.  A
    setting of 32,768 seems to be about right.  

    The settings for NT and 2000 vary; you need to see the eValid User 
    Manual for the specifics.

  * Optimize DeskTop.  You should select NT/2000 desktop settings to
    "Optimize Performance for Background Services".

  * Video Card Characteristics.  You may have problems if your video
    card has too little memory.  We recommend a video card with at least
    64 MB of SDRAM.
