Dear ismail,
I've checked the Conditional Logic plugin with your code and see it worked well. Here is my screencast:

I've measured via Chrome Console and see it took ~300ms to run all login, that's acceptable. Here is my screenshot:

I've also tested via really old Macbook Air and it took me average ~450ms.
Please check if there is something affected to this.
Cheers!
