[ale] Comcast DNS

Since moving from Charter to Comcast I've noticed that connecting to 
sites have drastically slowed down. My DNS config used to be:
Primary DNS: 64.94.1.1
Secondary DNS: 64.94.1.33
Tertiary DNS: (I don't remember for Charter)
DNS search path: nothing specified

Now my config is:

Primary DNS: 64.94.1.1
Secondary DNS: 64.94.1.33
Tertiary DNS: 68.87.68.162
DNS search path: hsd1.ga.comcast.net

When I do a nslookup of DNS 1 & DNS 3 I get:
[scott at ncc1701f ~]$ nslookup 64.94.1.1
Server:        64.94.1.1
Address:    64.94.1.1#53

Non-authoritative answer:
1.1.94.64.in-addr.arpa    name = ns1.acs.pnap.net.

Authoritative answers can be found from:
1.94.64.in-addr.arpa    nameserver = ns-c.pnap.net.
1.94.64.in-addr.arpa    nameserver = ns-d.pnap.net.
1.94.64.in-addr.arpa    nameserver = ns-a.pnap.net.
1.94.64.in-addr.arpa    nameserver = ns-b.pnap.net.
ns-a.pnap.net    internet address = 64.94.123.4
ns-b.pnap.net    internet address = 64.94.123.36
ns-c.pnap.net    internet address = 64.95.61.4
ns-d.pnap.net    internet address = 64.95.61.36

[scott at ncc1701f ~]$ nslookup 68.87.68.162
Server:        64.94.1.1
Address:    64.94.1.1#53

Non-authoritative answer:
162.68.87.68.in-addr.arpa    name = cns.s3woodstock.ga.atlanta.comcast.net.

Authoritative answers can be found from:
87.68.in-addr.arpa    nameserver = DNS103.comcast.net.
87.68.in-addr.arpa    nameserver = DNS101.comcast.net.
87.68.in-addr.arpa    nameserver = DNS102.comcast.net.

Any suggestions as to what I should use? And how would I manually set 
it, as I'm using DHCP form my Linksys router that only has places for 
DNS 1 & 2.

TIA
Scott
