John,
we are considering these nexus switches as a core for a small (for now)
exchange point, so there will definitely be multiple ports talking to
one and vice versa. Let's say the switch would be utilized up to 90% (45
ports in case of 5548, 90 in case of 5596), half of the active ports

These total numbers are not a problem, all ports are equal and all

this scenario if you have bursts of traffic going from many to one port

For example, block any internal hosts from browsing to www.microsoft.com

Steve,
Will this just block URLs or can it block all traffic to a domain? The
latter is what I'm looking for.
Say block ALL traffic (make a domain Dead to me) to google.com (no
ping, nothing to mail.google.com, maps.google.com.. etc.)
Thanks for the quick reply!

Go into your recursive DNS server. Add a blank authoritative forward zone for
google.com. Boom, it's dead to you.

Quick and simple configuration using the DNS engine and MPF on the
firewall.
However, I also prefer and recommend Matthew Huff's suggestion about
configuring your recursive/caching resolver to be authoritative for
the domain-label you're looking to filter and setting the records to
127.0.0.1.
I would use the caching resolver idea, but management also wants to have
the activity logged and have e-mail based alerting. I figured that I
could handle on the ASA through SNMP traps.

If may be the result of the SMTP/ESMTP inspection of the ASA, I'd probably
try removing that and seeing what response you get. I would also look at
DNS resolution of your mail server, as at least with Sendmail, if DNS
(forward/reverse) gets wonky, it can really slow things down..
