Hi Dave,
Thank you for your message.
You can see some basic overview here
Also you can find some articled regarding performance if you search this devnet. Its worth checking out e.g.
here
However if you search you will find some more.
You can turn off the scheduled tasks which you dont use which could give you a small performance gain (there are much more important factors, mainly caching options).
Let me know if you need anything else.
Kind regards,
Richard Sustek
