I tried all the suggestions with the same string that should locate a record at the ~17% of the file (~record number 170,000), the best response time still goes to grep :
grep took 17 seconds, 3 to show the match the res 14 scanning the rest of the file.
awk took 20 seconds
then sed as scottn suggested took 28 seconds
tried awk as franklin52 suggested and took 18 seconds
so in summary I'm still good with grep but my users are not happy to wait once in a while for 17 seconds to get their screen back with the response (neither my server performance if I have many users using the same look up).
I would be so nice to find a way to stop grep after that first match, response time would go down to 3 seconds! I guess I'll have to find another source for grep that supports -m and see if I can install it.

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.
