I don't recall a dedicated "CEF Process Switch" performance test, but an
educated guess is that it "performs" as well (rather: as bad) as the
old-style process switching, so between 5% and 10% of the performance
compared to interrupt switching. Take a look at
http://www.cisco.com/warp/public/765/tools/quickreference/routerperforma
nce.pdf for some sample perf figures..
