How does Xfinity speed test works ?

In order to provide accurate speed test results , comcast speed test  download and uploads small packets of data from your computer and after that some mathematical calculations are performed to determine current internet speed in Mbps.

Comcast Speed Test vs Ookla ( ) , who wins the battle ?

Most of you already know that ookla is a global leader in measuring the internet performance but is it really more accurate than comcast ?

The answer is both  “yes ” and ” no  ” , before thinking that i am mad wait for a minute because here is the reason behind my answer .

Comcast is the ISP (internet service provider) based  testing service while on other hand by ookla  is the Non-ISP hosted tool ,

That’s why sometime we are encountered with incorrect results because both of them works on  different benchmark .

Most of the time ISP based speed testing tool gives inaccurate result outside their countries due to lack of hosted servers  .

Important : so , if you are a comcast customer then it is more better for you to test internet speed with official  xfinity speed test tool.


Can I use xfinity speed test  if it doesnot  provide ISP services in my country ?

Yes , you can  measure  latency ,downoad and upload speed by going to their official website without any problem.

But i suggest you to use your own ISP based testing  tool or any other non-isp based speed test services such as :

  • by ookla
  • CNET  based speed test
  • Bandwidthplace

My opinion :

According to my observations Comcast or xfinity speed test tool is one of the best available service  to measure your current internet performance or metrics . The best part is its simplicity and user -interactive interface , with a single-click you can get all valuable statistics , but if you are not a comcast customer then i recommend you to use other Non-ISP based  testing services for getting more realistic results .
