I wonder if it shouldn't be a bit higher, though. Isn't 30 seconds too
low for a default?
I also had this thought. What would you suggest?
I don't know, 5 minutes at least. It should discard cache entries that
haven't been used in a while.
It my opinion the default should be for saving memory in VMs that are
mostly idle. If the VM is more or less active I wouldn't want to clean
cache entries that are used frequently.
How about 10 minutes?
