Does LambdaAttack do anything else more than just creating fake player and login?

[cyf-gh]

Hi, I am just using LambdaAttack as a fake player creator for continuous chunckloading in order to make some farms or red-stone machines keep running on my server.
However I have found that it causes a strong tps drop to even 5-10 tps when I create just 3 players using LambdaAttack.
Does this program do anything else more than just creating players and login? Like lag datapack sending or something else. If the answer is no, I may find some hardware reasons because I run LambdaAttack and my server on the same PC.
LambdaAttack really helps me a lot but I just cannot suffer such a low tps. I wish you can reply me as soon as possible.
Thanks in advance.

No actually it doesn't. It's planned, but was never implemented.

You could create a timings report. This will check for too-long running operations on the main thread. However asynchronous threads (in abstract simple terms - parallel program flow) will be ignored by timings reports. Such tasks could run on different CPU cores. This could also cause main thread to not get enough CPU time if they are too heavy.

This includes the testing tool. So remember running the benchmark tool on the same computer also can reduce the performance.
