The typical speed I see is 2M-2.5M nodes per second on this dual xeon box. let's take 2.0 as easier to multiply with. A hash entry for crafty is 16 bytes. Crafty doesn't probe the hash table in the q-search, so let's assume that is about 1/2 of the total nodes searched. So we are going to need to store roughly one million entries per second, or 16 megabytes. If you want to search for 100 seconds, you need about 1.6 gigabytes. If you want to search for 5 minutes, then about 5 gigabytes. You get the rough idea...
