It's still more than 1-2 orders of magnitude faster than the original Pi. And probably 2-5x faster than a Pi2.
That said you could get a $2 USB Ethernet adapter on ebay ... and plug it into the pi and experiment with that. The Pi will probably show your internet down since it's peripherals all hang off it's overloaded USB bus.
The P4 ought to handle it with ease... as far as that goes lots of people have used much slower machines for routers/firewalls. Rather than using wireshark which is a rather heavy handed but comprehensive solution, you just do as suggested here with dnsmasq
How to log all my DNS queries? - Unix & Linux Stack Exchange
And filter the log for dnsmasq output.... just about as good as wireshark and probably more performant than running without the system as now your dns queries are cached by a local machine. The TCPDUMP answer there is also good.
If you get it working on the P4 getting a mini PC is probably a decent idea... as the power savings alone will pay for itself. A P4 computer costs between $100-300 a year to leave running vs the mini PC costing about 10 bucks a year.

dnsextd
dnsextd(8) BSD System Manager's Manual dnsextd(8)
NAME
dnsextd -- BIND Extension Daemon
SYNOPSIS
dnsextd
DESCRIPTION
dnsextd is a daemon invoked at boot time, running alongside BIND 9, to implement two EDNS0 extensions to the standard DNS protocol.
dnsextd allows clients to perform DNS Updates with an attached lease lifetime, so that if the client crashes or is disconnected from the net-
work, its address records will be automatically deleted after the lease expires.
dnsextd allows clients to perform long-lived queries. Instead of rapidly polling the server to discover when information changes, long-lived
queries enable a client to indicate its interest in some set of data, and then be notified asynchronously by the server whenever any of that
data changes.
dnsextd has no user-specifiable command-line argument, and users should not run dnsextd manually.

mDNS(1) mDNSResponder(8)
For information on Dynamic DNS Update, see RFC 2136 "Dynamic Updates in the Domain Name System (DNS UPDATE)"
For information on Dynamic DNS Update Leases, see http://files.dns-sd.org/draft-dns-update-leases.txt
For information on Long-Lived Queries, see http://files.dns-sd.org/draft-dns-llq.txt
BUGS
dnsextd bugs are tracked in Apple Radar component "mDNSResponder".
HISTORY
The dnsextd daemon first appeared in Mac OS X 10.4 (Tiger).
