Hardware looks good.
Have you tried rebooting into safe-mode? Normally safe-mode is slower than a standard boot, but if safe-mode starts up much faster that would indicate one of your startup applications is causing problems. Start up your Mac in safe mode - Apple Support
If you have inconstant performance (some Apps open quickly, others/most open slowly) the issue may be Fusion Drive logistics. Items stored on the SSD component will open 10-20x faster than items stored on the HDD component. MacOS tries to be smart about what is kept on the SSD, but there is only enough SSD for ~8% of your data and sometimes important applications end up in HDD space. If you want everything to open consistently quickly you will need a high capacity pure SSD. If you think a 3TB Fusion Drive is "real slow" you may want to look at external Thunderbolt drives such as an OWC Envoy Pro.

You are most welcome! 😄
Thank you. It doesn't take long - 5 minutes tops! 😉
Make sure you see "Safe Boot" in a red font in the top corner of your screen before you restart into normal mode.
Please download and run Etrecheck. The free version is sufficient.
Copy and paste the results into your reply. Etrecheck is a diagnostic tool that was developed by one of the most respected users here in the ASC and recommended by Apple Support to provide a snapshot of the system and help identify the more obvious culprits that can adversely affect a Mac's performance.

Check Etrecheck's Privacy settings and make sure the checkbox for full disk access before running:
Then we can examine the report and see if we can determine the cause of the problem.
just ran it in safe mode, it was a tiny bit quicker but everything was lagging. I've restarted it now and just seeing if i can sort some files and stuff to clear some crap off the system. Does it speed stuff up if you partition the drive or is there a better way to have it set up. I use creative suite and deal with some pretty large files at times
Thankyou for your help I will give it a try and see if it makes a difference. Many thanks
Not had chance to try it yet will report back once I have
Thanks for the help, i unplugged my backup drive to see if this would help performance. Just setting it back up now. Thanks again

I'm interested to know if you noticed any significant improvement after starting in Safe Boot mode.
Please advise.

GREAT! That was the purpose of the exercise! 😄
Please remember to make sure that your Time Machine is making back-ups as it should!
Please start with a new question if you have further concerns.
Thank you.

Ah! The plan wasn't to RUN it in Safe Boot mode - just START it like that!
How is it running now that you have restarted in normal mode?
