Hamachi fast relays std version?

Hi there,

What does it mean fast relays regarding Hamanchi std subscription, does this improve data file transfer speed?

I have tried the free version of Hamachi and I have found that the data file transfer speed very poor from one LAN to my other LAN even both are on Fiber. So back to my question will my data file transfer speed improve on the paid std subscription of Hamachi?

Regards
