Hi,
This is my personal opinion.
On jspeed (or other similar plugins), compressing js and css each page requires a lot of server cpu. It might slow down your first time cache (page cache will be generated slower). Sometime compress algorithm does not work well and can break your layout. So I do not recommend using plugins like jspeed, or JCH Optimize.
But if it works fine on your case, you can use it without concern.
Regards
