How did you meassure it? And do you use nepomuk for desktop search as well?

For me (Memory usage with KSysguard, not the Virtual Size):
Kontact (not only KMail, but also KNode, KOrganizer, etc.): ~800MB
Akonadi server: 131MB
Akonadi IMAP resource 1: 44MB
Akonadi IMAP resource 2: 5MB
Akonadi Maildir resource: 113MB
Akonadi Nepomuk feeder: 48MB
Mailfiter agent: 20MB
Kolab proxy: 8.5MB
POP3 resources: 2x4MB
Notes resources: 2x4MB
KABC resource: 4MB
MySql: 370MB

Total: 1.5GB, but note that this is basically the full PIM suite with debug 
build, not only KMail.

If we add Nepomuk (that technically is not only PIM):

Nepomuk sotrage: 100MB
Nepomukfilewatch: 11MB
Virtuoso: 231MB

So another 400MB. 

Can we reduce this memory usage? Probably. Although the bits themselves are 
not too much, we could look at what could be done for the bigger users, like 
Maildir (although note that I have 300000 mails under it), the server and 
especially Kontact. Kontact is the top memory usage for me, followed by 
mysql, Xorg, firefox, virutoso, amarok (all these when I don't run KDevelop 
;) ).
We could indeed save on shared database between Nepomuk and Akonadi once 
virtuoso's sql support fits Akonadi's needs.

Now back to your statement: what kind of memory usage would you feel 
acceptable for all this functionality?
