I have a problem with one of the performance tests. I am using jmeter 5.4.1 with docker. Everything is behind f5, proxy, firewall etc but that is not the problem. My "headache" is that after about 30 minutes my throughput drops to almost zero. I'm looking for a solution to this situation and my question is : Does jmeter have the ability to count/summarize all requests sent, even if it doesn't get a response? The destination server gets everything that jmeter has sent, but I'm not sure if jmeter doesn't save requests only when it gets responses to them. example of my tests:

Update: Active thread over time :
I don't have any timeouts set in my script and the response time is ok. No extended response times and yet the number of transactions is so mediocre....
