If you are looking for full addresses, do not enter in the list a part of them (for instance the 15 first char)
It will be faster to enter full addresses.
That's true that there is 2^96 priv key for an address and if you perform 2^96 key you will find a collision but that would also imply that you search for the whole address range, on the blockchain there is no 2^160 address with fund and it is not possible to have a file of 2^160 address.
So if you want to find a collision between 2 priv key that give the same address, consider using BTCCollider which would require "only" 2^80 operations to reach the collision.
