True causes of performance bottlenecks

Performance Testing is used to find out the bugs which degrade the performance of the application. But did we ever try to find out the exact reason for these bugs? If we know the causes at the beginning of the SDLC then performance issues can be mitigated up to some extent. And, this behaviour can lead you to become a Performance Engineer.

I found an ultimate article in which the writer (JM) has uncovered the causes of performance bottlenecks. Read the article to know what are they?👇

Types of Memory Leakage, Reasons and Resolutions

Memory leakage is one of the common bottlenecks found during performance testing. Ideally, endurance (also known as soak) test is conducted to identify the memory leakage in the application. But sometimes the system fails due to memory issues even in the load test. In such a situation, there could be multiple reasons which make the servers out of memory. 

Today, I found a good document in which most common out of memory error types are listed out along with reasons and generic solutions. I would suggest to download and save this PDF because in future when you try to resolve the bottleneck related to memory issue then this document could be a key treasure for you.

Type of Performance Test Defect

During Performance Testing, many defects are found which can be termed as bottlenecks. Performance Testing defects are usually different from the functional testing defects because they have moreover occurred at the network or server side. As far as I am confident most of the clients do not have proper defect management for performance testing bottlenecks that lead extra time, effort and money when the bottleneck re-appeared in future releases. 

Leave this topic here only because today, I am sharing an article written by Naveen Kumar describing the category of Performance Testing Defects. This article will help you to understand the category and severity of the PT bottlenecks. Refer to the link and get the knowledge:
