Default Apple's 'filevault' faux pas. Important!

The recent OSX 10.13 installer has enabling Filevault (a disk encryption feature) selected by default. If you just cruse through the setup screen after a fresh OSX install you might miss this and end up with Filevault enabled!

This is a feature that severely sacrifices performance for security. Something appropriate for an FBI agent or bank CEO with sensitive data at risk of physical access but no need for any performance.

Open System Preferences, click Security & Privacy, click the Filevault tab.
If you see it turned on, please turn it off and follow the prompts to un-encrypt your drive.

Also note that OSX updates are sometimes failing with Filevault enabled. Leads to a full OSX reinstall and restore.
