Wow! thats a LOT of helper processes for 2 users.

They start fast enough though.

Oops! major problem with DNS on this server.

An old rule-of-thumb in computing is to start with the first reported
problem and see how many of the following disappearr

For you that is as Squid suggests "Please check your /etc/resolv.conf file".

The slow server seems to have no DNS servers available. This could be
causing any kind of problems for the helpers later on. All of the extra
delay is during the startup process of the helpers.
