Obviously, “if you’ve got the RAM, flaunt it.”

Well, if you say so... :-D

I found it interesting, so I tried some of BrowserUk's test scripts. I populated the rands.dat file - 0m48.948s. Then I loaded it into a hash - 0m37.042s. The array was significantly faster - 0m28.708s. Loading the data into an array took a fair bit of RAM, but since I am only using roughly 7GB of 12GB, I didn't encounter any swapping - 0m59.864s. Going on the first numbers, I must have something faster in my system already. However, not ten times faster. If you don't have the RAM, you may need to get it. :-)
