FIXED SUMMARY quicker than grep

I would like to thank JV711, who through his questions pointed out a big
mistake that I made in my summary.
After all the trouble that i had making the script running quicker on
solaris, I tested the tools on debian. (to avoid loading the system
more). As a results the results are faulted!
so here is the problem and the solution (and the new results table):
A large group of non-root users needs to find out information about
customers through ldap. 
ldapservers are pretty loaded as they are, and doing extra calls to them
(searching) increases the load to even more.
so as a quick solution, for simple searches we use an ldif that has been
taken from the ldap every night, and we 'grep' for information through
this file. its simple 1 grep and four seds.
Last summary i had run all the different greps on a non solaris box, and
it showed that agrep was the fastest. Its not true in Solaris though...

Here is the list of the tools that I tested in solaris 9 (sun4u, sparc,
ultra5):

the grep,egrep fgrep are the solaris versions,
the ones with the g infront are the GNU grep versions.
Perl is a quick search with perl described in Unix Power tools (oreily).
gwana is the bourne shell script which formats the output.
ykanello is my username :)
