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.

niff(7) Miscellaneous Information Manual niff(7)
NAME
niff - Network Interface Failure Finder (NIFF) introductory information.
DESCRIPTION
The Network Interface Failure Finder, NIFF, is a facility for detecting and reporting possible failures in network interface cards (NICs)
or their connections. Detection is done by monitoring device counters and attempting to generate traffic to NICs suspected of having
failed. Reporting is done using the Event Manager subsystem (EVM). NIFF does not drive failover operations; that is the responsibility of
the application that subscribes to NIFF's EVM events. Appropriate courses of action may include selecting another network interface for
communication or if it is a clustered environment, migrating an application. See nr(7) for further information.
At the heart of NIFF is the traffic monitor thread. The traffic monitor thread tracks changes in the network device's counters, and notes
if the received packet counter remains unchanged since the previous snapshot. As long as the counter continues to increase, the traffic
monitor thread assumes the NIC is functioning. See nifftmt(7) for further information.
The traffic monitor thread can monitor any network interface. The configuration utility, niffconfig, is used to activate and administer
the traffic monitor thread. See nifftmt(7) and niffconfig(8) for further information.
The Network Interface Failure Finder daemon, niffd, is a traffic generator for network interfaces that have been classified inactive by the
kernel traffic monitor thread. The purpose of niffd is to get the interface packet counters to increment, signifying the interface is still
alive and well. See niffd(8) for further information.
