Slow MIP Solving, how to speed up?

Hi,

I'm trying to solve a seemingly complex MIP Model that has two integer variables. At first I solved the MIP Problem with half the time-steps I am aiming for with the following parameters and logfile:

threads 8
method 2
names no
timelimit 1000000
scaleflag 2
MIPFocus 3
MIPGap 0.004
NumericFocus 1

I found out with calculating only a little amount of timesteps that the parameter threads 8 was faster than using all 16 threads.. Is this normal?

The following log file was the result:

So it took 4.5 hours which is still okay for me.

But if I double the timesteps and run it then it takes at least 23 hours after which I interrupted the Model. I received the following logfile:

I am aware these are a lot of timesteps and a solving time of maximum 24 hours would still be alright, but it seems to move very slowly. I have tested different MIPFocus and method parameter but its either much slower or very similar in solving time. Is there something to do? And why is the thread count 8 seemingly faster than using up all threads on the machine?

And finally I ran the same problem with less timesteps for testing on a machine with only 8 threads and much less RAM and compared it to this machine and using 16 threads but all the same parameters otherwise. And the machine with much less CPU/RAM solved the problem faster than this machine which didnt make sense to me, how could this be? The only difference is that the more powerful machine has Gurobi 10.0.3 while the weaker one uses 9.5.2.

Thanks in advance.
