[Winpcap-users] why pcap_findalldevs run about 30 seconds

[Gianluca Varenni]

This can be due to a number of reasons.

Do you have IPv6 enabled on your machine? this might slow down things a lot.
Are you calling pcap_findalldevs from within a service that starts at boot time (maybe before you notify the SCM that the service is up and running)?

Also, I strongly suggest you to migrate to WinPcap 4.0. It contains a huge number of bug fixes, and we do not provide any support for such an old version of WinPcap.

Have a nice day
