Reduce DNS Lookup & Connection time, total 400ms is taking too long (especially from outside US)

SiteCatalyst is very nice tool, but it's sometime rather slow in beacon response.

Here is a screenshot from Firebug connection log.

 

omniture_firebug.png

 

SiteCatalyst's JavaScript beacon is consuming visitor's browser load time like:

  • 100ms for DNS lookup
  • 150ms for connection
  • 150ms for 1st byte response

total 421ms for tracking, where Google Analytics is only using 31ms.

 

These days, visitor's time = money.

 

They say:

Omniture's products are to bring more revenues for their customers BUT, its slow response time is DECREASING their PVs & revenues, isn't it?

 

When I want to decrease DOM-ready time down to 2s, SiteCatalyst is cunsuming 20% of those time, and it's too long.

 

Please cut those time down to like total 100ms, especially DNS lookup time from outside US (it sometimes takes more than 150ms!).

You could also consider using remote data collection server located in Tokyo. We are migrating one of our websites to this to see how it improves.

Thank you for good information! I didn't know such a scheme like RDC already exists. I'll contact my account manager.

 

But, if I use Asia/Pacific RDC, visitor to my website from US/Eurpoe suffers from latency.

 

Hopefully, Omniture build CDN-like system to forward each visitor to appropriate data collection server and everyone should be happy.

yes, it's CDN-like. The RDC uses DNS for the nearest server. So Asia will use Tokyo, Europe will use London and US will use the 2-3 in the States.
