Re: Does the number of extents affect the performance?

Isn't it amazing that virtual memory is now common place. Touted as fabulous idea when new! But virtual disk available on the Uni 1100/2200 series back in the '70's never caught on. You could have 10 gig of virtual disk but only 3 gig of real disk. The OS did the roll-ins/roll-outs automatically.

Ah, the good old days!
