Mac address / brand identification super slow and/or incomplete

[geoslake]

Hi, and thanks for this wonderful tool !
I was looking for a tui network scanner and stumbled upon this one, its super great.
However, the identification of the ips part doesnt seem to work well, on my LAN it only identified 3 brands (vs Advanced ip scanner 15).
But this morning when i came back to it (was still running from yesterday), it identified 5 more...something wrong here i guess ?

Thanks

I'll second geoslake's comments. About 40% of my MACs, hostnames, and vendors are missing.
