Also depends what you're opening. Services under a client takes longer as it's connecting to various pieces of information and doing a full asset report or domain list can also take longer when it's reporting hundreds or thousands of entries.
Then it's a case of where is the VM, local or hosted, as obviously off site or shared hosting can have variable performance vs a local VM on a dedicated host of your own. If you're doing a lot of data editing, like importing your data, it can slow down for a bit, then you'll see performance return to normal the following day etc.
For a point of reference, we'd have half a dozen staff using (not hard out, we're not driving ticketing yet), 200 clients, 1100 contacts, 1400 assets, and it's on Debian 12, 4x CPU and 4GB ram, on an older host (but one of our own, local to our main office). It's reasonably snappy, just slows down on the previously mentioned screens.
