This is Why Load Testing Is Important Not Just Before Release

This is Why Load Testing Is Important Not Just Before Release

After a short conversation with one of my customers he told me that a month ago he invited a “Load Expert”  to perform load testing just before the company release the product.
After the “Load Expert” exam the system he said every thing will be all right, 30 people is nothing I’m 99% sure nothing will happen.

the customer asked him to perform the load test any way just to be sure… and the test passed just fine!

Then I got a call from the customer and he asked me to perform a load testing on their system.

Hey told me that he wants a second opinion, I exam the system and I found the major scenarios want to test.

After running the Load Test (Using Team System Team Edition – Obvious) we saw that even 30 users on their system cause very very very bad behavior.

Diving into the little details, me and the developers found couple of major problems (Security,Performance and more)

 

The story ends with – 2 month delay of the release.

Team System Team Edition Load Summery

I didn't understand what you want to say. Basically, its not a question of time, it's question of methdology.

Guy,

Sometimes the threshold rule on % Time in RT checks will be fired when there really isn't a problem, so before you spend a lot of time trying to figure this out, you should also look at the value for the performance counter "Total Runtime Checks" in the same category.

You may be able to use the VSTS performance profiling tools to help determine what exactly is the problem.

Hey Yuval,

Every thing is Time = Money.

I didn't asked any question just want to show that even if the number of people is low there is still can be lot of load issues.

I definitly agree with you, Load Testing SHOULD be a part of the development process and executed as soon as possible. The earlier you detect performance problems, the easier it is to correct them.
