No its not. Some apps bind to the ipv6 loopback for example in error and
this causes delays. Others try to lookup/use addresses in that protocol
and need to timeout.

You might be assuming that everyone codes applications properly for every
conceivable circumstance encountered:)

It's another argument whether or not that's Fedora's fault for enabling it
and I won't get into that pissing contest. Since none of my networks use it
I simply make a point to disable it as part of all other required config
when I roll out a system.
