Mail Server Load Testing

Mail servers can be load tested by sending a large number of emails to a mail server over a specific period of time and recording how the server behaves as it receives those connections. Organizations may require this type of load testing for several reasons. For example, they generally receive a consistent, low level of mail traffic with intermittent periods of high traffic. They may also expect growth within a certain period of time and want a mail server that is capable of scaling with the organization’s growth.

Load Tester 5.4 Released!

Our goal with Load Tester 5.4 was to build the easiest to use load testing tool, even if you had no experience with load testing. It should just make sense when you look at it, with every button in the right place and all of the right information at your fingertips. We’ve spent most of 2013 reworking the user interface, trying out several different ways of doing the normal load testing workflow, until it both looked great and let us get load testing done as quickly as possible.
But of course, user interface improvements weren’t the only changes: we threw in … Continue reading »

Scheduling Load Tests with Load Tester 5.4

Many of our customers want to run tests off-hours to minimize collateral inconveniences. For example, if the rest of your QA team is working on the same test server as you, it might behoove you to run a load test at 2:00 AM when the team is asleep. Load Tester has had the ability to schedule off-hours tests for years, but the feature remains a frequently asked question among potential testers.
In Load Tester 5.4’s streamlined user interface, you can schedule a test from the ‘Control’ menu by choosing “Schedule Load Test.” A “Scheduled Operation” dialog will appear, and you can … Continue reading »

How Much Bandwidth Do You Need To Do a Load Test?

One of the common questions people are interested in is finding out how much a test is going to cost. There are a lot of factors that go into this equation, such as getting an appropriately sized testing license, configuring a test server environment, reserving hardware for Load Engines, and bandwidth costs between the Load Engines and the content delivery servers (such as a CDN or origin servers). Let’s take a look at just how we might calculate the bandwidth charges that are involved in a single test.
If your site is only needs to support a few hundred users, then … Continue reading »

Measuring Web Page Load Times using JMeter

At last count there were over 65 separate commercial load testing tools out there, but few with the name recognition of the open source program JMeter. Often people will call us up and ask to compare Load Tester with JMeter, but I only had a cursory look at it many years ago, and couldn’t speak from recent first-hand knowledge. So, when someone called me last week asking about JMeter, it seemed like a good opportunity to give it another look.
