33 or 66 tick for ze

[gamemann]

Hello all, i have a ze server. It is 50 slots. And i got it full before on another machine but i wanna make it as stable as possible.
Now this and another server is the only one on the machine.
Here are the specs:
processor: intel xeon 1230 @ 3.2 ghz
ram: 16 gb
internet: 100 mbps
I don't know if i should make it a 33 or 66 tick server. And which is better.
And also can anyone tell me if the processor can handle it?
I'm also stuck between max update and cmd rate. I am not sure if i should make it max update rate to 33 or 66 same with cmd rate.
Please tell me how you think i should do it. Trying to make a perfect 50 slot ze server at a good stable fps.
Thanks,
Gamemann
