Yes, for best results increase both, however do not enter
more than your RAM size is because then Windows would swap to hard disk
anyway.

with Premium Data
Thank you, Tomasz, I'll try that. Do I also need to
change the "in memory cache size (max. symbols)"?
The PremiumData
database with all the backlisted symbols is huge, so maybe I just haven't
sized the data preferences big enough.

If you want caching and faster use of MS databases, go to
File->Database Settings
and change "Local database storage" to
"Enabled", also you may go to
Tools->Preferences->Data and
increase 'in-memory cache'.
