Open Chrome's Task Manager (Shift+Esc) and close heavy tabs and extensions, update Chrome, disable unneeded extensions, clear cached files, toggle hardware acceleration, and test another browser to see if it's your network.

The short explanation

If every browser is slow, the cause is your connection, DNS or PC. If only Chrome is slow, the cause is Chrome’s extensions, profile or settings.

A common hidden cause is Continue running background apps when Chrome is closed, which keeps extensions running all the time.
