Does performance actually get worse? Or does it just take 100,000x longer to process a 100,000x larger file? About how many matches are you expecting?
There are memory-heavy ways to do it faster, but they're not really applicable to massive files. You could try divide-and-conquer: Run as many simultaneously as your CPU and disks can easily handle, sort their output individually, then merge them in one final step.
