user authorization

[pascal tscharner]

Hi

We'd like to define different groups of Users(i.e. Access to HTTP,FTP..)

when we've defined different acl like:
acl http_users proxy_auth "/opt/squid/etc/http.group"
acl ftp_users proxy_auth "/opt/squid/etc/ftp.group"
there are about 20000 users defined in the http group
it takes a long time to startup(reconfigure) the squid..
is this just normal or do we have to define it different?!

cheers
