MacBook Pro 13 2019, work and performance?

Question

macOS

Hello! I have a base Mac with Mojave on board (10.14.6 with the latest security patches). Lately I have been noticing micro-lags and not at all smooth operation of the system (as if it gives out 40-50 fps, plus scrolling in safari lags on most sites). I cleared the caches (Onyx program), the laptop is not cluttered with programs and all sorts of files, what could it be? Will a complete rearrangement of the axle help?

Good afternoon!
In general, there were the same symptoms. I have MPB 2018 pretop version.
In short, it is most likely caused by the fact that you updated the operating system. And unfortunately for several years it has not been possible to update it. Everything needs to be taken down and cleaned up.
And that's exactly what I did - but upgraded to BigSur. The difference in speed is simply indescribable. The main thing to remember is that you must definitely reset the NVRAM PRAM immediately before installing a new axis.
