Amos,

I am not using a raid, although my single drive performance might be slow?
Will need to check on the i/o.  When I do run squid or make any changes to
the config I do get a lot of :

2009/10/16 14:44:08| WARNING: You should probably remove 'xxx.com' from the
ACL named 'bad_url'
2009/10/16 14:44:08| WARNING: 'xxx.com' is a subdomain of 'xxx.com'
2009/10/16 14:44:08| WARNING: because of this 'xxx.com' is ignored to keep
splay tree searching predictable
2009/10/16 14:44:08| WARNING: You should probably remove 'xxx.com' from the
ACL named 'bad_url'

Would this by chance do it?  There is about 22,000 sites in the bad_url
file.

Thanks
