Hi Matt,
I'm not sure why you're seeing such slow performance in Decaf - but maybe we can narrow it down if you can answer a few more questions:
- Which DBMS are you using?
- Where is the database server? (Is everything on one server, or do you have a separate DB server?)
- If the database server is separate, what are its specifications, and how is the front-end server connecting to it?
- How much CPU power is available to the VM?
- Which version of Decaf are you running?
- Do you have Decaf configured to hide the Settings and/or Navigation blocks?
- What are your Moodle navigation settings? (Site administration -> Appearance -> Navigation)
- What other non-core plugins/modules are you running?
-Paul
P.S. I'm happy to help you investigate this outside of the forums, and then report back here with any findings - if you'd like to do so, send me a private message and we can take it from there.
