I have an Early 2011 MBP 13" (yes, you read right). It was slow as hell on High Sierra and the fan was running all the time, CPU at 99% at some times without any real workload. Then, some random shutdowns started that never occurred before. Used TM backups a few times but still slow and unreliable.
That was the moment I decided to set up the systems fresh from scratch on a blank SSD (keeping the old one in a safe place as a backup option): Now, the MBP is running great (for its age), quiet fan except for high workloads and no runaway 99%-CPU processes.
Of cause, your mileage may vary, but I would suggest trying a fresh install from scratch and only install necessary programs. Don't rely on a TM backup.
