Snapapps/Edgy slow to import .xml files in 2021.  Is there preventative maintenance required on the host?

We've noticed that Snapapps/Edgy is running a lot slower for our students in 2021, even with relatively small datasets and small Snapapps/Edgy applications the time to import .xml files has increased noticeably.
Is there preventative/cleanup maintenance required on the host? Has Snapapps/Edgy been moved to a slower host?
