Every day we see people coming on here trying to figure out how to mine. Some of those people have multiple computers, some have many computers. I remember yesterday two people were specifically asking about how to set up multiple computers to mine to one wallet. I have no idea how many computers either of them have or how many other people like that didn't post. There was an optimized Windows miner released recently that doubled the has rate on a lot of hardware. With the price going up like crazy yesterday that was clearly going to attract a lot of people.
All of this is going to rapidly drive up the amount of mining and the hash rate, which in total still isn't that high, only 5000 or so computers.
