Are you sure memory speed hasn't improved? I was seeing latencies around 300ns
to 1000ns in both cheap PCs and mid-range workstations in 1995. Now i see 100ns
to 200ns in cheap PCs. Not as impressive as the CPU core speed increase, but
still worth having. (Of course Crays were fast, even a Cray-1 was about 120ns i
think, but i never got to use them.)
