[squid-users] slow DNS resolving

Hi,

I have Squid Cache: Version 2.5.STABLE3.
The problem is that it slow resolves addresses on peak times. Usually it says "The following error
was encountered: Unable to determine IP address from host name for ..
The dnsserver returned: No Address records"
The cache.log file is filled with messages: "ipcacheParse: No Address records"
The cachemgr.cgi util shows:

Internal DNS Statistics:

After several "refreshs" the page is showed.
But if I use browser without proxy enable in IE- pages are showed quickly. The client and proxy server use the same DNS servers.
What about option to recompile squid with "--disable-internal-dns" and increase "dns_children" ?
I've noticed that problem usually occurs with sites like google, yahoo.
