It's been about 6 months or more since I upgraded my internet connection to double what I had. I had a 60Mbps down and I think 15Mbps upstream. Now I have a 120Mbps/10Mbps respectively. Interesting enough I started using the router provided by the ISP. I started noticing that my DNS resolution was slow, crawl basically. So I did a local DNS cache on my machine hoping to speed things up. It did a tiny bit, but not a significant change.. The I started google-ing harder, no concentrating on DOCSIS systems, and Cable modem/routers. I came a cross a person who had the same issue, and the suggestion to fix it worked for me as well. All I had to do is turn of flooding detection, and my DNS resolution became super fast, I had DNS resolution in the range of ~4000ms some sec, now it's below 100ms where it should be. I finally feel like I have my connection that I had before the upgrade, even though it was a stupid router setting :(
