When you increase the parallelism of eValid playbacks, you will probalby exhaust various Windows resources as you increase the browser user (BU) count.
There aren't any hard and fast rules on what you'll run out of first, but our experience suggests that the limits may be in this order: available RAM, CPU time, virtual memory, screen update speed, input/output bandwidth, and "graphical data objects". In
VERY approximate order!
There are special instructions in the eValid LoadTest documentation to help you make adjustments on your machine (machine image). We plan on at least 100 BU's per machine image per user, and up to 1,000 per machine.
But -- and we have to say it even if we don't want to -- "your mileage will vary." It's best to experiment!
