LoadTest

What is a LoadTest?

By running multiple copies of the eValid browser simultaneously,

eValid can impose heavy work loads on a WebServer. You experience

real performance, because there are no virtual users.

How Much Load? How Many Users?

Your mileage will vary! Depending on the RAM capacity and CPU speed,

eValid can launch and create load for 1000+ real BUs.

eVlite: Load for URLs Only

eVlite is used to exercise load on URLs only. As it uses less server

capacity, eVlite handles up to 1000 users per instance. This

shortens the time of your test runs considerably.

Lessons Learned

Using the eValid load engine is an excellent way to test the performance of your WebSite and server under heavy load sessions. You

can see how multiple simultaneous requests are affected by the backbone of the Web, the

design of your WebPage(s), and the limitations of the server where your WebSite pages reside. One can also gather data on

how well your site performs when many users make requests for your WebPages.
