It seems to me that we are missing an important thread is
NOT what CVP does to performance that is the real issue.  I think we
all know that for every level of security we add (be it electronic or
human) there is a performance hit.  The QUESTION is what price are we
willing to PAY to achieve (this particular) level of security???  If I
am willing to have minimalist security, I can go with a router with a
few filters and get X performance.  If I add an Application Gateway
Firewall like SecurIT (my brand...substitute yours here ;-) then I
have a lot of additional protection but I perhaps have X-1
performance.  If I want to add URL blocking, then I might have X-2
performance...etc.  Each security admin or manager must make the
decision as to what price will I pay for what level of performance. 
That, IMHO, is the real issue to deal with.  Once you make that
decision, then you can deal with whether brand X CVP is faster or
slower than Brand Y.
