CPAN.pm takes like 15 minutes at these two steps. I have added more URLs to urllist. Most of them use HTTP.
Why is this taking so long and how can I make it faster?

Go to CPAN Search website and search for the module that you wish to download. In this example, let us search, download and install XML::Parser Perl module. I have downloaded the XML-Parser-2.36.tar.gz to /home/download
Also, in normal circumstances, the cpan client is expecting the full name of the module, not one part of the name, and not the name of the zip-file. So cpan Path or cpan Tiny will attempt to install different modules. (One called Path, the other one called Tiny.)
In case it is not installed, go ahead and install it. To run cpan you can use the following command: If this is the first time you are using cpan you will need to proceed with the basic configuration by answering a few simple questions. To install the same Perl module we installed before you can use the following command:
Before you can use CPAN, you need to install the Perl-CPAN package, using the DNF package manager as shown. Note: Although most Perl modules are written in Perl, some use XS – they are written in C and so require a C compiler which is included in the Development Tools package.
If you do a lot of stuff with CPAN, configure and use a local MiniCPAN. Let it update automatically when you aren't paying attention to it, then install quickly when you're ready for it. The first time you set it up it will take forever, but it's a forever you don't have to care about because you don't have to watch it.
daxim recommended sqlite and cpanm, which you can use, but if your network is the slow part, you'll still have to use the network with either of those.
What you're seeing in that output snippet is your CPAN client downloading a couple of huge text files that are the indices into what is current on CPAN. The packages file has over 125,000 lines, but compressed its only about 1.5Mb. However, that file is updated hourly and CPAN.pm always wants the latest one. It's one of the huge design warts on the system, but that's what you get with the oldest and longest used CPAN client that has ever existed.
cpanm gets around that by not paying attention to the index files. It goes right to the CPAN search site to figure out what's the latest version and then goes with it. That might work better for you.
You said that you added more URLs. This is another problem for the CPAN client. Once it finds a URL that returns a good status, it goes with it, even if you've chosen something in the middle of Niger that has a 56k modem uplink through a laggy satellite where the operator is typing in the ones and zeroes by hand.
In my latest version of the cpan command line tool, which comes with CPAN.pm (but is usually a little behind, which is my fault), I've added a mirror pinging feature that will find the best mirrors for you based on ping times. That's only checking latency though, and throughput can still be a problem.
All of which is why I use a MiniCPAN.

To make CPAN indexes work faster, install CPAN::SQLite and and configure use_sqlite to 1.
Alternatively, install App-cpanminus and run the cpanm client which does not need a local index.
