I've been following the advice of Hamish and others and tweaked our NW 6.5
SP 4 servers and so far things look pretty positive. One question:

The one change I did not make is to create the _netware\_ndsdb.ini file
with the lines:

preallocatecache=true
cache=125829120
cacheadjustinterval=15
cachecleanupinterval=15
blockcachepercent=50

What do these settings do? How do they improve available logical space?

Thanks,

Pat
