And here are times from my office machine, which is a 
NeXTStation 105/8 running off a network. I'll denote
launches by "net" and "loc" to indicate wether it was an app on
local disk or on a disk on the network (incidentally, the network
disk I mount is on a Cube/040/24MB/330MBMaxtor)

When I launch local stuff, there is swapping that occurs. I expect
this to get much better when I upgrade to 20MB RAM, shortly; judging
from the above stats, I could get a factor of 3 in launch times.
Note that the change from 030->040 gave roughly a factor of 2--3
improvement as well.
