How important is WordPress Performance speed?

[MorStone]

Work on the sites the same way I’d work in the traditional setting of WordPress.
Once I'm through with editing my page, my friend recommended me to publish it as static HTML wordpress site.
He put forward a suggest trying Flatsite.com static wordpress site generator (https://flatsite.com/). Do you think it will work fine for me?
What are your advice? Could anybody help?

This secures the website. A static website won’t store users’ personal information; however, it is imperative for the information requested to not be seen by unwanted snoops. I would like to say that flatsite.com is offering "Start at $1" plan for the 1st month. So you can try them out for only $1.

You will be pleased. I am happy. FLATsite's team feature is quite valuable if you’re working vertically on different projects or collaborating with multiple third parties. Without any adjustment or request, they went ahead and include all my webpages url in google search engine.
