Slow webpage loading

Sup,

Having some trouble with what I thought was my DNS cache, then found that the distro of linux I'm using doesn't have a DNS cache enabled.

Webpages load really slow for me now initially.  A website like craigslist for example will take 15-20 seconds to load, but once it has I can browse that particular website just fine.  Following links pages load in about 1 second like normal.  A speed test has reported that my download and upload is 10mb and 1mb respectively, and I have reset my modem and router to no avail.

Can anyone help?  It is Ubuntu linux and I am using the Firefox web browser.  I have flushed Firefoxes cache as well.

figured it out, firefox trying ipv6 first and waiting for web page responses to time out before switching to ipv4.  about:config and changing "network.dns.disableIPv6" to True fixed my problem.

Thank you very much,I have read it now.
