Good day, my beloved forum, what would I do without you.  
I inherited an old project on Hippo 12.6.8, and users are complaining that /cms is running very slowly. I’ve checked the configs and added some values, but the problem still persists.  
What would you recommend for a quick/fast solution to this issue?  
Thanks in advance ❤

Hi,  
At first I’d look at the bundle cache size, to double (or quadruple?) that, depending on the available memory. It the size of the in-memory repository layer that can cause slowness if it’s too small.

See [Configure the BundleCache - Bloomreach Experience Manager (PaaS/Self-Hosted) - The Fast and Flexible Headless CMS](https://xmdocumentation.bloomreach.com/library/administration/configure-the-bundlecache.html) .

Then maybe optimize page size settings? See [Configure the CMS Folder Listing Page Size - Bloomreach Experience Manager (PaaS/Self-Hosted) - The Fast and Flexible Headless CMS](https://xmdocumentation.bloomreach.com/library/administration/configure-the-cms-folder-listing-page-size.html)

Cheers, Jeroen

hi @B_A do you have some monitoring in place to observe CPU/memory/garbage collection/threads etc? They might indicate some issues as well like not enough heap or blocked threads.

Could this be related to the fact that we have version 16 of postgres? We had version 11 before, we moved
