Yes - may be. But updating the list is a really simple job.

May be - but "squidguard" does a really simple job: it looks into a list
of not allowed domains and URLs and then decides wether to allow or to
deny. That job doesn't need "constant updates".

The squidguard job is working with a really big blacklist. And working
with some specialized ACLs.
I know "squid" can do this job too - and I maintain a schoolserver which
uses many of these possibilities of "squid". But then some other people
has to maintain the blacklist. That's no job for the administrator in
the school.
"better traffic performance" may be a criteria, but (p.e.) blocking porn
URLs is (in schools) a criteria too.
Teachers have to look at "legal protection for children and young
persons" too.
Please excuse my gerlish.
