remember that -t 20 uses 20 times more memory than -t 1 .

Might you be better off with a smaller number of threads, and use the memory 
for a huge cache for oracle queries?

 both for ZServer and for ZODB Accesses? If i change these
 settings, which one will allow me to have around 20 threads available to
 access an external Oracle DB (the zserver or the ZODB)?

You'll also want to change the number of database connections.  If
you use FileStorage, put the following in a custom_zodb.py file in
your Zope software home or instance home (if you run an instance
home setup):

import ZODB.FileStorage
import ZODB.DB

filename = os.path.join(INSTANCE_HOME, 'var', 'Data.fs')
Storage = ZODB.FileStorage.FileStorage(filename)
DB = ZODB.DB(Storage, pool_size=25, cache_size=2000)

The pool_size parameter is the number of database connections.
The number of database connections should always be higher than the
number of threads by a few (it doesn't make sense to have fewer
database connections than threads).
