Thank you, I used the "-f" option, adding "-F" as well made it significantly faster.

I have another question related to this use of grep. If I instead wan to list all items in file1 that does not exist in file2 by negating how can that be done?
I tried the -v flag but it did not do this, am I missing something here or is it not possible to do this with grep alone? I have used -v before with grep but never combined with -f that is new to me.
EDIT:
I managed to get this working with the following script, any comments or tips if there are easier ways to accomplish the same this would be appreciated.

zgrep
ZGREP(1) General Commands Manual ZGREP(1)NAME
zgrep - search possibly compressed files for a regular expression
SYNOPSIS
zgrep [ grep_options ] [ -e ] pattern filename...
DESCRIPTION
Zgrep invokes grep on compressed or gzipped files. These grep options will cause zgrep to terminate with an error code:
(-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*). All other options specified are passed directly to grep. If no file is specified, then the
standard input is decompressed if necessary and fed to grep. Otherwise the given files are uncompressed if necessary and fed to grep.
If the GREP environment variable is set, zgrep uses it as the grep program to be invoked.
EXIT CODE
2 - An option that is not supported was specified.
