High Sierra has made my MacBook Pro abysmally slow

I have a mid-2012 MacBook Pro Retina and after updating to High Sierra (10.13.2 beta) my laptop is borderline useless. I can't run Spotify and any internet browser without it slowing to a crawl, YouTube videos won't even play properly, and navigating Final Cut Pro X lags two seconds behind every input I do. Sierra ran like an absolute dream but High Sierra is the polar opposite. I don't have a Time Machine backup for Sierra so I can't install that. I'm tempted to just do a clean wipe of High Sierra at this point. I've also opted out of beta profiles because I'm not dealing with this again.

Does anyone have any insight on rectifying these problems or will I just have to wait for Apple to release an update so my laptop isn't a glorified paperweight?

Well, this might be one solution, however it is not 100 % sure a cure for all similar lagging cases;

I am having very same problem, MBP 13 Retina Late 2013 is having extremely high kernel_task all the time, machine is unusable totally! It has 8 GB RAM + i5 cpu + 256 GB SSD (M2). Disk space is used less than 100 GB.

OSX was Sierra, once lid was closed and reopened next day and machine was awful slow. Upgraded to High Sierra. No help. Tried to reset SMC, NVRAM, safe boot and reinstalled original OSX Maveric + formatted HD. No help.
Installed latest OSX again, high Sierra. No Help. Lost even machine Serial id if looked via My Mac. ***

Tried to run Ubuntu Linux from USB flash - runs smoothly, no problem with CPU load etc. Booted High Sierra back and problem continues. Decided to install Ubuntu in HD (dual boot ) and now Linux Ubuntu is running smoothly without problem / high load. Before that I consulted Apple Help desk, no help from there.

Second Apple in this family (first was iPhone) and 100 % guarantee that this is the last piece of really pain in the *** purchased from Apple - newer ever comes to this house new Apple.

Start by uninstalling CleanMyMac3.

Roger that. Uninstalled CleanMyMac. Am I able to download a dmg file of 10.13.1 or can I not go back to a GM release and will have to wait for the next GM release?

I wouldn't attempt to downgrade, but check the documentation on the beta. If you wipe your disk you can install the GM High Sierra from the AppStore.

Good to see I'm not the only person who is having issues with this. Did downgrading back to Sierra help?

Same here, High Sierra killed me.
