@ongoto, reason#1 for the inefficiency is the many rewrites of the output file with sed.
The following uses bash for writing the output once. Still using awk for a fast+precise lookup of the pattern file. (Could be replaced by an inner while loop in bash using the same technique as the outer loop.)
Of course awk is much faster than bash, and this tasks fits 100% for awk.

dpkg-www
DPKG-WWW(1) General Commands Manual DPKG-WWW(1)NAME
dpkg-www - program to remotely open a WWW Debian package browser
SYNOPSIS
dpkg-www [-s|--stdout] [-h|--host host] [query]
DESCRIPTION
dpkg-www is used to remotely control a WEB browser and open a dpkg URL on the local host from an interactive shell or script.
If the command is invoked while running under X-window the script will try to find an installed X browser to open the specified URL. If
not running under X it will try to use a text browser instead.
If Netscape is found and a Netscape instance is already running it will be asked to open the dpkg URL on localhost with the optional query
supplied on the command line. If there is no browser running, it will start automatically a new one.
The functionality provided by this program is identical to running a web browser with the -remote openURL(http://localhost/cgi-bin/dpkg)
argument or opening the same URL from within the browser.
dpkg-www-installer is an helper application which can configured in the WWW browser for web installation. It should never be invoked
directly by the user.
OPTIONS -s, --stdout
Redirect output to stdout. Requires one of the text browsers (lynx, lynx-ssl or links) installed.
-h, --host host
Send the query to a remote host, where dpkg-www must be installed.
query Specifies an optional package name, an absolute pathname or a query argument which is passed to the dpkg cgi-bin. See dpkg-www(8)
for more information about the use of the cgi.
FILES
/etc/dpkg-www.conf
~/.dpkg-www
Configuration files for dpkg-www. It is not necessary for these files to exist, there are sensible defaults for everything, but you
can specify your preferred www browser with the DPKG_WWW_BROWSER variable, for example: DPKG_WWW_BROWSER=mozilla
EXAMPLES
dpkg-www
This would open a dpkg URL on localhost listing all the installed packages.
dpkg-www bash
This would open a dpkg URL asking info on the bash package.
dpkg-www -h pisolo bash
This would open a dpkg URL asking info on the bash package on host pisolo.
dpkg-www 'dpkg*'
This would open a dpkg URL listing all packages matching dpkg*.
dpkg-www /bin/bash
This would open a dpkg URL asking info on the package(s) owning the file /bin/bash .
dpkg-www depends=svgalib
This would open a dpkg URL listing all packages depending on svgalib.
dpkg-www --stdout depends=awk | grep ^ii
This would list on stdout all packages depending on awk and grep all lines of installed packages.
