Firefox&Chromiun page scolling always lags. Sometimes the pointer lags. Window movement isn't smooth.

How to make ubuntu faster?

I switched to KDE. That's much faster than GNOME shell.

sudo aptitude install kubuntu-desktop

The propriatary linux nVidia drivers have always been buggy. I gave up with them in 16.04 and now stick with the default open source kernel driver nouveau. If you purge your system of nVidia drivers nouveau will take over.
