Frank, I’ve never heard of this. Couple of thoughts besides Noel’s:

What version and build of BIAB is this, and what version of Windows?

You said it’s getting worse. When did that start, and what changed?

Does your hard drive have less than 15% free space?

What antivirus do you use?

Have you checked Task Manager? Sometimes when I boot up, my very fast PC turns to molasses as Windows, Adobe, iTunes and Malwarebytes etc. all decide to download updates! Or if a program is stuck hogging the CPU, you’ll see it in Task Manager. Even BIAB can be open in another instance and be running in a window hidden behind etc.
