faster way to loop?

Sample Log file

IP.address Date&TimeStamp GET/POST URL ETC
123.45.67.89 MMDDYYYYHHMM GET myURL http://ABC.com
123.45.67.90 MMDDYYYYHHMM GET myURL http://XYZ.com

I have a very huge web server log file (about 1.3GB) that contains entries like the one above. I need to get the last entries of all the different IPs that has myURL in it? Is there a quick way of looping? My idea was

# Get all the Unique IP addresses and then proceed to check each
cat weblog | awk '{print $1} > ip.list

for i in `cat ip.list`
do
cat weblog | grep $i | grep myURL > lastpages.lis
done


each day has around 3000+ unique IP entries and a day's log is about 48MB. with this process, it takes around 30 mins to process a days worth of data. is there a faster way to do this?

URI::URL(3)						User Contributed Perl Documentation					       URI::URL(3)

NAME
URI::URL - Uniform Resource Locators SYNOPSIS
$u1 = URI::URL->new($str, $base); $u2 = $u1->abs; DESCRIPTION
This module is provided for backwards compatibility with modules that depend on the interface provided by the "URI::URL" class that used to be distributed with the libwww-perl library. The following differences exist compared to the "URI" class interface: o The URI::URL module exports the url() function as an alternate constructor interface. o The constructor takes an optional $base argument. The "URI::URL" class is a subclass of "URI::WithBase". o The URI::URL->newlocal class method is the same as URI::file->new_abs. o URI::URL::strict(1) o $url->print_on method o $url->crack method o $url->full_path: same as ($uri->abs_path || "/") o $url->netloc: same as $uri->authority o $url->epath, $url->equery: same as $uri->path, $uri->query o $url->path and $url->query pass unescaped strings. o $url->path_components: same as $uri->path_segments (if you don't consider path segment parameters) o $url->params and $url->eparams methods o $url->base method. See URI::WithBase. o $url->abs and $url->rel have an optional $base argument. See URI::WithBase. o $url->frag: same as $uri->fragment o $url->keywords: same as $uri->query_keywords o $url->localpath and friends map to $uri->file. o $url->address and $url->encoded822addr: same as $uri->to for mailto URI o $url->groupart method for news URI o $url->article: same as $uri->message SEE ALSO
