I can't reproduce this problem:

% time perl -MLWP::UserAgent -e 'LWP::UserAgent->new->post("https://facebook.com", { data => "foo" }) or die'                                                
perl -MLWP::UserAgent -e   0.15s user 0.01s system 40% cpu 0.397 total

Has there something changed in LWP::Protocol::https Net::HTTPS
IO::Socket::SSL Net::SSLeay or something else, or is this some local
environment thing?

Also no issue with IPv4-only hosts:

% time perl -MLWP::UserAgent -e 'LWP::UserAgent->new->post("https://twitter.com", { data => "foo" }) or die'
perl -MLWP::UserAgent -e   0.13s user 0.02s system 36% cpu 0.415 total 


Cheers,
gregor, confused, as Guilhem (in message #71) could still reproduce
        it at 7 Apr 2019
