iptables interception normally does not have any speed difference compared to directly configuring the proxy settings.
"Speed" in terms of bandwidth or latency? A site I worked at saw browsing latency drop significantly after switching away from transparent proxying.
It should not have any noticeable impact on either.
Of course, it could have been something else besides the iptables redirection - extra DNS lookups, perhaps?
Yes, there will be extra DNS lookups when doing interception, but this should only be noticeable on the first request and only if the clients uses different DNS servers than the proxy. If both uses the same DNS servers then the difference should not be noticeable even on the first request as the response is cached in the DNS server, immediately available for Squid to use.
