I think you might be able to squeeze a little bit more speed using -n 0x4000000000000 -k 8192. If you saved your 1TB bloom filter using -S, you can re-use it with the different -n and -k values. You have another 0.5 TB ram available, have you tried -n 0x4000000000000 -k 12000 so you can max out your RAM? Even then, you'll run out of money or die before 135 is found.
