Microsoft Edge Slowed Me Down

For many years I have used Google as my search and browser page. I tried the other day to switch and go to Microsoft Edge and had many problems surfing around and I imported my bookmarks and did not get the complete list of the sites I visited. I had problems with google but I had to back to google because I couldn't solve and issues I had. Using Edge slowed my computer down. I got frustrated. Can anyone help me.
