Viewing Perl Modules .. possible to cache views in DataTables?

I’m using Webmin 1.760 with Authentic Theme (latest).

I note that it takes quite some time (3-4 minutes) to load and render Perl Modules.

And then when I look at a module and click on “Return to modules list” the page loading starts again with spinner showing for another 3-4 minutes.

Is possible to cache these rendered views in right frame and only update the view (DataTable) if there is a change in modules?

I also note that although I manually installed LWP::UserAgent it does not show up in the modules list.

However I do see (for example) WWW::Curl in the long list of Perl Modules.

Comparing paths of these two modules this is what I see from my command line …

perldoc -l LWP::UserAgent
/usr/local/share/perl/5.18.2/LWP/UserAgent.pm

perldoc -l WWW::Curl
/usr/lib/perl5/WWW/Curl.pm

I don’t know why Perl Modules are installed in these different lib paths.

Should I consolidate all Perl Modules into /usr/lib/perl5/
for Webmin to see them in Perl Modules list??

For example there is no LWP::UserAgent in /usr/lib/perl5

Also what is the significance of Perl Modules shown in bold text vs. normal text under Module column?
