Woo-commerce plugin slows down my computer

Hello,

I work with Storefront-Child theme in localhost on Wamp server.
Since I added the woo-commerce plugin, my wp-admin is extremely slow, almost blocked. Every operation takes minutes. When I try to add or edit a product, I have frequently this message:
“Connection lost. Saving has been disabled until you’re reconnected. We’re backing up this post in your browser, just in case.”

Can anyone help me with this?
Thank you
