I use those at MTA level. That dropped 62.000 messages, and only 378
spams were detected by SA during that time. I guess that saved a lot of
CPU.
Since you seem to have a problem with DNS queries ("if I disable RBL
checks and razor, pyzor and dcc the delay goes away"), I would suggest:
- make RBL checks at the MTA already
- get permission from RBL maintainers to make a zone transfer to your
box, and run a local named or whatever. By that, you only have local
DNS queries, that should help a lot.

Each of them are different, altogether they help a lot. I use all of
them, but I'm not in a situation where I have problems with delay.
First try RBL at MTA, and possibly you have enough CPU cycles left then
to reactivate that checks.
