In single user mode 4D does data catching but when you switch to multi-user
mode all catching is turned off and every thing has to be written back to 
disk. If you are on a network this can slow you done even further. The 4D 
server which should be very close to shipping now, should address this issue
completely.  4D server will do data catching on the server so all request for
data are handled in the most efficient way.  Whats even more, if you have a
output layout displaying a selection of records 4D server will only send
across the fields on the output layout and not the entire records. This aloan
will speed up things considerably.

During both of the demos I've seen the server was on a PowerBook 170 using
localtalk being accessed from another PB 170, IIci, and Quadra 700 and the
speeds were impressive.
