We have heard that baseline and benchmark test in the performance test. I have shared many tips related to heap dump analysis in the past. To continue the treasure of performance engineering related to heap dump, today I am sharing an article which described the calculation of shallow and retained heap size in a very simple way along with the examples (especially last case). Read out this informative post and grab the knowledge.

Master in the little master form

'Master Apache JMeter' which is written by 3 developers belong to Apache JMeter team and prefaced by Alexander Podelko. Either you can purchase this book (Link to buy) or read the free sample (Link to read free sample). When I say "Master in the little master form"; I mean this book's free sample only, so Enjoy reading and learning!!

Performance Testing is a kind of art. It needs clear designing, logical scripting, meaningful result analysis and at last a tuned application which every client wants. Since many things, a performance tester needs to align during PT windows so there must be a check-list which can give a clear idea what needs to be done, what is completed and what is pending; without missing any important task. Vitaly Friedman has shared a front-end application performance testing checklist which will help you out to keep eyes on the completed and open tasks.

Performance Engineering; a trendy domain in PT world. Performance Engineering is a vast field which requires a deep knowledge of technology, application, architecture, integration and many more things. 

I always get one question from the performance tester that he/she wants to move in the performance engineering field, but do know how to start?

Today, I am going to share the Bible of Performance Engineering named "Beyond Performance Testing" written by R. Scott Barber. Actually, these are the PDF links covering all the basic and advanced topics of performance engineering. I am sharing you the link of Introduction page in which all the links are given. So, read it and learn the PE concepts:

Today's treasure is related with Heap Dump and Thread Dump Analysis. Pierre-Hugues Charbonneau has 15+ years of experience in Java application development and troubleshooting. He has published some treasure articles on Heap Dump and Thread Dump Analysis. It is worth to recommend his blog. You can read the blog and save the URL for future reference. Must read this post (especially for those who are interested in PE)

To upskill the knowledge for a performance tester, it is necessary to grab the understanding of performance engineering concept. GC or Garbage Collection log analysis is one of the important stuff which helps to identify the root cause of the issue related to memory. We have also discussed the same last Friday but in a different way. 

"gceasy" is a well know GC log analysis tool, they have published an article which comprises of GC analysis metrics and how it is different from APM tool. Must read this post (especially for those who are interested in PE):

Today, most of us use Postman for API testing. Postman is a very simple tool to operate. Jacob Sharir (Blazemeter) has written a good article on the same with a subject line "How to Use Postman to Manage and Execute Your APIs" and provides basic knowledge to implement and operate Postman tool. Read the article and get a basic understanding of the same:
