Nixon, also, i would suggest keeping an eye on the amount of rows in the vm_stats table. In my case, ACS hasn't been removing them properly and as a result i've accumulated over 25m rows in that table, which caused the slow response in the acs gui.
Something like this: SELECT table_name, table_rows FROM information_schema.tables WHERE table_schema = 'cloud'; check the vm_stats rows. If you need to remove some old data, you could do something like this: DELETE FROM vm_stats WHERE timestamp < '2024-05-20 00:00:01'; that will remove all rows with the timestamp older than 20th of May 2024. If you have a lot of data, you might need remove the data in shorter increments. I've found that my /tmp folder didn't have enough space, so i had to play around with dates to remove all the old data. Now, the ACS ui is pretty fast and usable again. Hope that helps.
