The comparitives of other similar RBLs covers the of issue mail throughput.
DynaStop only needs the IP address, not the entire email.
Resources used by DynaStop in operation:
For the DynaStop client:
%Cpu: 0.0
%Memory: 0.0
Memory Footprint 1712K
Running the DynaStop client 50 times, avg 0.0317 msec (from strace)
For the DynaStop server:
%Cpu: 0.0
%memory: 0.4
Memory footprint: 9920K
Only one server is needed to handle several thousand clients. The DynaStop
server has been tested to 500 connections/second.

I will do some research on spamassassin's cpu/memory consumption and post
the results.

I did answer your question. DynaStop is not a list of IP addresses, but
rather a collection of patterns to identify dynamic IP addresses.
Here an example: A dynamic IP address, say 126.34.45.55, which is listed by
zen and currently DynaStop.
If the user of that IP address decides to register a domain and provides the
reverse DNS of microwidgets.com, DynaStop automatically disregards this IP
address, zen does not.

Reread the last sentence, PBL clearly lists dynamic IP addresses

Not really. In a clustered mail server setting, the $domain variable can be
passed to DynaStop for domains that want no filtering at all. Rather then
adjusting a large number of exim configurations, the administrator need only
adjust the DynaStop server conf file. Plus there is no dependancy of a
network file system, which on a cluster is, in and of itself, a challenge.
