CR35iNG update recommendations (from 17.0.8 to 17.1.2)

Hello everybody.
I wanted to ask you experts for an opinion.
I have a CR35iNG updated to SFOS 17.0.8 MR-8.
I wanted to know, is the 17.1.2 stable enough for this model? Would you recommend updating?
I've heard that the update slows the firewall down a lot.

Currently the system is using:
CPU - 15%
Memory - 70%
Bandwidth - 700KB
Sessions - 860

Looking forward to your advice,
Thank you.
