Any Ways to Boost WordPress Performance Speed?

[Jango]

What ways can you recommend me to boost my wordpress performance and speed?
The thing is that one of my co-workers draw my attention to FLATsite.com (https://Flatsite.com/) static wordpress site generator.
Would like to know your views on it? Have you tried it?
Any other suggestions please?
