With some tweaking it may still be possible to get this brute force solution to work fast enough, but it's not looking good. I suspect your are running out of physical memory and the system is swapping, how big is the file1.txt and how much physical memory do you have on your system?
You could consider retaining some of the work from previous scans. This really depends on your dataset and leads to the following questions about your data.
How static is it?
I'd assume the zip file contents don't change much, but perhaps you remove old zips and add new ones?
How about the contents of file1.txt is this completely different each night? Are any items searched for searched for again at later dates? (For example if we know the XYZ wasn't in the zips lastnight and it's searched for again, all we need to scan are files added since last night's scan).

get-oui
GET-OUI(1) General Commands Manual GET-OUI(1)
NAME
get-oui - Fetch the arp-scan OUI file from the IEEE website
SYNOPSIS
get-oui [options]
DESCRIPTION
get-oui fetches the Ethernet OUI file from the IEEE website, and saves it in the format used by arp-scan.
The OUI file contains all of the OUIs (Organizationally Unique Identifiers) that have been registered with IEEE. Each OUI entry in the
file specifies the first 24-bits of the 48-bit Ethernet hardware address, leaving the remaining 24-bits for use by the registering organi-
sation. For example the OUI entry "080020", registered to Sun Microsystems, applies to any Ethernet hardware address from
08:00:20:00:00:00 to 08:00:20:ff:ff:ff inclusive. Each OUI assignment represents a total of 2^24 (16,777,216) Ethernet addresses.
Every major Ethernet hardware vendor registers an OUI for their equipment, and larger vendors will need to register more than one. For
example, 3Com have a total of 37 OUI entries. Organisations that only produce a small number of Ethernet devices will often obtain an IAB
registration instead. See get-iab(1) for details.
This script can be used to update the arp-scan OUI file from the latest data on the IEEE website. Most of the Ethernet addresses in use
belong to an OUI registration, so this is the most important of the files that arp-scan uses to decode Ethernet hardware addresses. You
should therefore run get-oui occasionally to keep the arp-scan OUI file up to date.
The OUI data is fetched from the URL http://standards.ieee.org/regauth/oui/oui.txt and the output file is saved to the file ieee-oui.txt in
the current directory. The URL to fetch the data from can be changed with the -u option, and the output file name can be changed with the
-f option.
The ieee-oui.txt file that is produced by this script is used by arp-scan to determine the Ethernet card vendor from its hardware address.
The directory that arp-scan will look for the ieee-oui.txt file depends on the options used when it was built. If it was built using the
default options, then it will look in /usr/local/share/arp-scan.
OPTIONS
-h Display a brief usage message and exit.
-f <fn>
Write the output to the specified file instead of the default ieee-oui.txt.
-u <URL>
Use the specified URL to fetch the raw OUI data from instead of the default http://standards.ieee.org/regauth/oui/oui.txt.
-v Display verbose progress messages.
FILES
ieee-oui.txt
The default output file.
EXAMPLES
$ get-oui -v
Renaming ieee-oui.txt to ieee-oui.txt.bak
Fetching OUI data from http://standards.ieee.org/regauth/oui/oui.txt
Fetched 1467278 bytes
Opening output file ieee-oui.txt
9274 OUI entries written to file ieee-oui.txt
NOTES
get-oui is implemented in Perl, so you need to have the Perl interpreter installed on your system to use it.
get-oui uses the LWP::Simple Perl module to fetch the data from the IEEE website. You must have this module installed on your system for it
to work. This module is available on most distributions, often called libwww-perl. It is also available in source form from CPAN.
You can use a proxy server by defining the http_proxy environment variable.
