Running 100 browsers to generate load
Posted: Fri Dec 07, 2012 1:43 pmIn running 100 browsers to generate load, aren't you afraid that all you're doing is measuring your local channel capacity?
We have found that the channel capacity even with 100 eValid instances running in parallel is very seldom "used up."
The percentage of channel usage does vary quite a bit...but even with very heavy loads on the driver and very large pages to download...we rarely seem more than 10% of available channel bandwidth used up.
In fact, even though eValid instances do consume a lot of memory, running 100+ of them on a user account on a machine does not really tax the input/outpu capacity of the machine. When we do 1,000 BUs using a cloud-based machine image even then the I/O channel percentages stay below 5%.
So, while your point is a fair one, experience shows that the loading approach is valid up to 100 BUs per machine and beyond.
