Does anybody experiencing same as me that Cake Poker is laggy?

I dont think my broadband is the problem because any other poker site is working fine and smoothly. I usually play early morning from 2 or 3am onward, which is most people here in UK are still sleeping.

I tested my broadband speed and here are the results as of 6:00-05am:
