In theory it is possible if you have a fast enough computer.  I've never
tried it myself, but here are some tips to get Wireshark to run faster:

However, you're probably better off running dumpcap (a command-line
program that comes with Wireshark).  Dumpcap's entire purpose is to
capture packets as fast as possible without interpreting them; in fact,
it's the back-end capture mechanism that Wireshark uses.  Dumpcap lets
you save the traffic to a file and then you can read it in with
Wireshark later.
