Apache JMeter helps my testing analysis by providing precise reports; the HTML format report gives me the exact transactions, response times, and graphs that show average response times, as well as throughput per second.

JMeter can be integrated with most open-source platforms like Grafana, Prometheus, or even with custom-made tools by extending it and integrating from GitHub.

They can provide support for other protocols as well, and with AI becoming more prominent, they can implement features where it can generate code by itself based on the results or provide suggestions.

One drawback which I can see when I compare it with other tools is the amount of cache that it uses, the memory that it uses.

The GUI of Apache JMeter is not that user-friendly because we have many proxies, and we have to record through the proxy.

I have not seen a return on investment right now, as there is no improvement in Apache JMeter and reduction in cost, but I save time and reduce costs with Apache JMeter.

To improve Apache JMeter, reducing the complexity of load generators and distribution testing would be beneficial.

For UI automation, it is limited and therefore rates a one.

One area for improvement is the ability to decrease load suddenly during tests. Currently, we need to use multiple separate JMeter instances to simulate reductions in load, which isn't ideal.

While using Apache JMeter, we are unable to view the graph while the test is running because it consumes resources, which is a drawback. With BlazeMeter, you can view the results in real-time.
