What takes 40 seconds? If you're just running updates then the client
should receive acknowledgement.

You'll need to tell us something about your design. See my first reply
for what people will need.
As to whether your hardware is a limit - nobody can say without knowing
what you're doing with it.
Four obvious things leap out though:
1. Why does it take 6-8 queries to calculate one value?
2. What makes it necessary to calculate one cell at a time rather than
all at once?
3. Are you vacuuming enough, and how have you established this?
4. Why are you doing this in a database at all? For 4800 values I'd just
calculate them all in my application and then store the lot in one go.
