Hi,

I've encountered an issue causing similar effects.
You may want to check how the local name of the machine is
declared in /etc/hosts.

In my case, after installation, the hostname (say for example:machine)
was declared as an alias on the IPv6 loopback (::1), even if it was
a true IPv4 adresse. The file looking like:

/etc/hosts:
127.0.0.1              localhost.localdomain       localhost
::1         machine   localhost6.localdomain6     localhost6

The correct /etc/hosts should have been:

127.0.0.1              localhost.localdomain       localhost
::1                   localhost6.localdomain6     localhost6
V.X.Y.Z                  machine.mydomain.tld        machine

The erroneous file was causing random and strange slowdown.


Hope this help.
