Re: [squid-users] Low performance even with low number of users

Thanks, but I figured out what the problem was.
It was outside squid. A security solution was scanning every request
to the proxy and preventing the conexion to be made, so that's why,
for the squid, the access was fast, because actually the request o
squid was.

Anyway, solved. Thanks!

Luiz.
