We're using 2 DEC Alpha 2100 Model4/200 with 256M and 26G of disks, we have experienced and increase of speed on CPU intensive tasks but we had earlier versions of DEC Alpha 3500 and 4600. At first when we brought up the 2100s they seemed very fast and din't even notice the bootup.

But with Oracle - the machines still are unbalanced with respect to IO and CPU. This leads to jobs to bottlenecked on IO and it not much better with the 2100s as users access the system.
