    dns causes web pages to open slowly - 10 to 15sec delay


    the web page will eventually open up or if i hit refresh

    2.6.35.11-83.fc14.i686
    bind version 9.7.3

    i have disabled ipv6. using ie for browser.

    etc/resolv.conf

    nameserver 127.0.0.1
    nameserver 1.2.3.4 - my isp
    nameserver 2.3.4.5 - my isp
    options single-request
    options timeout:1

    etc/named.conf

    zone "." IN {
    type hint;
    file "named.ca";};

    zone "2.168.192.in-addr.arpa." IN {
    type master;
    file "192.168.2.db";
    allow-update { key "rndc-key"; };
    notify yes;};

    zone "aaa.com." IN {
    type master;
    file "aaa.db";
    allow-update { key "rndc-key"; };
    notify yes;
    };


    options {
    listen-on port 53 { 127.0.0.1; };
    listen-on-v6 port 53 { ::1; };
    directory "/var/named";
    dump-file "/var/named/data/cache_dump.db";
    statistics-file "/var/named/data/named_stats.txt";
    memstatistics-file "/var/named/data/named_mem_stats.txt";
    allow-query { localhost; localnets;};
    recursion yes;

    dnssec-enable yes;
    dnssec-validation yes;
    dnssec-lookaside auto;

    any help would be appreciated.

    Open a terminal and type the command nslookup google.com

    Code:
    rcgreen@blue:~$ nslookup google.com
    Server:		127.0.0.1
    Address:	127.0.0.1#53

    Name:	google.com

    Address: 74.125.91.105
    Name:	google.com
    Address: 74.125.91.147
    
    rcgreen@blue:~$
    It will reveal if the name server on the local host is working
    and resolving names. If it fails and times out, the system
    will be slow.

    i fixed that dns timeout error but there is still a noticeable delay compared to setting it up as a cache only server.
