Calculating the load and load pattern is probably the trickiest issue in conducting website performance tests.
First, remember that there is a difference between users, transactions, page views and hits:
· One user can conduct several transactions (e.g., visit a Homepage, search for a product, view a product’s details, buy a product, etc.)
· One transaction can create several page views (e.g., add products to the shopping cart, go to the checkout, enter credit card, etc.)
· One page view can create multiple hits (e.g., framesets, images, applets, etc. for a single webpage)
Webserver Stress Tool is a powerful HTTP-client/server test application designed to pinpoint critical performance issues in your web site or web server that may prevent optimal experience for your site's visitors.
