Load Impact is a new online service that allows you to see how much traffic your website can handle
Load Impact generates simulated user traffic to your site – for example it might simulate that 50 users are trying to load your web pages at the same time. While simulating the traffic from these 50 users, it also records how fast pages are loaded from your server. This lets you know how fast your site is (as experienced by a user) when it is being accessed by 50 users at the same time.
To test your website, enter your URL on the front page on Load Impact, click Start Test. And then choose Start Free Test:
You will get your report, after the testing is finished(it takes several minutes). As free test, Load Impact will test up to 50 visitors to your website. Here is the test report of ZackLive.com.
This post guides you how to interpret the report.
