Why the update did slow my MacBook pro down so

Why the update did slow my MacBook pro down so much? What could be in the last update of El Capitan to slow my Mid 2010 GHz Intel Core 2 Duo Macbook Pro 2.66 down so much?   He has never run it slow before! Everything takes more time in all areas. Could I have made a mistake during the download and installation?  If so is it possible to force a re - install the latest update?

I don't know if I can restore back after an update of this size. Everyone has similar problems or have thoughts on what could be wrong? I know it's far from being a State of the art Macbook Pro. But it was working fine before the update.

Any thoughts would be really appreciated. I can't afford to buy anything newer right now.

Thank you
