I just got back from DevCon6 (the 4D developer conference) and found out 
some stuff regarding this...

According to Laurent (the author of 4D) the server cache does NOT cause the
users to wait.  It is a process just like everything else and shares time
with other processes.  It is the SYSTEM cache that will cause the delays. 
He
recommended a small SYSTEM cache - 32k, and a large 4D server cache.  The
more
memory 4D gets, the better...
