Dear Periko, so here is what you ask to me:

CPU x 8
RAM x 12 GB
HD x 50 GB

And this is /etc/squid/squid.conf file:

cache_mem 4096 MB

what is squid's real memory usage?
It can be much much more than 4G, 4G is only cache, but squid also uses
buffers and indexes.

memory_replacement_policy lru

I would use heap gdsfhere for betterhit ratio, but this should not be a
problem

cache_dir aufs /var/spool/squid 25000 16 256

What's squid CPU usage?
here can be a problem. aufs cache_dir can be only used by one process.
Maybe you should try rock store for cache_Dir

fqdncache_size 4096

I don't see any reason to specify this. too low fqdn cache can result into
repeated DNS fetches.

acl manager proto cache_object

doesn't squid complain here? the "manager" acl is predefined since 3.4 iirc.
Are you sure squid uses this config file?

auth_param basic program /usr/lib/squid/squid_ldap_auth -b
"dc=company,dc=com,dc=ar" -f "uid=%s" -h ldap.company.com.ar -v 3
auth_param basic children 5

aren't there too few children? it can result into waiting for authentication
result before client is allowed.
what does squid log say?

acl QUERY urlpath_regex cgi-bin \? \.css \.asp \.aspx
cache deny QUERY

this is useless for a long time. urlpath_regex causes squid eat much of CPU.
disable this.

acl gedo dstdomain .gde.gob.ar
always_direct allow gedo

you have no cache peers defined. This is therefore useless.

I've just changed the new proxy to test environment and it works very
well again....I get lost.

see the limits above. Some of them may be low for a production system.
