What reviewers say
Scalable Distributed Load Testing with Clear Performance Metrics & Reports
“It mimics a crowd of users hitting your app at the same time, which is how you actually catch the bottlenecks. Need more load than one machine can generate? Spread the test across several. While it runs, it tracks response times, throughput, and error rates, then charts all of it”
Performance testing becomes easier using JMeter
“Easy to perform performance testing using JMeter. I can easily perform load testing by increasing number of threads on any application.”
Mastering Performance Testing with JMeter
“Helpful for load testing. I like various numbers of listeners to show the results data. Easy to use for performance testing.”
