If you're using the tooltip scanning method, I'd recommend keeping a cache of items you've previously scanned, so you don't scan them again. Store them in a table with the item links as keys and the levels as values, and then have GetItemUpgradeLevel return the stored value if it exists, or if not, set the value before returning it so it's cached for next time.
