Make Sure Your Time to First Byte Doesn’t…Bite

For my upcoming webinar about improving performance for greater customer satisfaction and conversions, I harken back to the early 2000s and a service called TrueTime that timed each line of code to look for areas of improvement.

In those days, we started with C++ code and would time machine cycles to give an accurate timing of how long each line of code took to execute. This coupled with how many times that line of code was called would give you a performance improvement that if you were lucky would be a half a second. Unless it was really bad code, you could not get blood out of that stone anymore.

Today when we look at a waterfall chart, there are more entries that are not our infrastructure than parts we own. That puts performance tuning in the hands of your partners and when you look at the first entry of the waterfall there is the first step down the yellow brick road, DNS.

As I work with customers that have varying environments, one thing remains the same. That first entry can be tuned with very little effort, like the Lion you just need some courage.

Unlike the Tin Man, I have the heart to show you the difference in using a managed DNS solution from Oracle Dyn. Here are a couple of examples we will drill into during the webinar.

“I checked a box for DNS services when I registered the domain.” And what does the Great Oz give them? 156ms of DNS latency vs Dyn at 46ms.

“My ISP told me that DNS is included in my package.” And what does the Great Oz give them? 439ms of DNS latency vs Dyn at 46ms.

With a one second delay resulting in a 7% decrease in website conversions, even the Scarecrow knows that DNS optimization is the right path.


What we did not talk about during the blog but will during the webinar is DDoS, Hijacks and Leaks, oh my! I look forward to seeing you at the webinar.
