Page Speed Insights for www and non www sites

[Marketing_Optimist]

I'm testing a client site for speed and I'm getting different results when I test www and non www. What's causing this from the same site?

• Non www scored 37/100 for mobile, very concerning
• www scored 54/100 for mobile, still problems but not as severe

Can anyone shed any light on this please?

Try the speed test again. Speed tests don't usually show the same results every time. Every other time I test my site it reads 89/100 and then when i retest i get 94/100. This can all depend on how quickly the server responds at the time.

Furthermore, there is clearly a lot of work to do before you can even begin to worry about these results

Would you be willing to share the domain?
Does the site render the same in the preview?

My first thought is that you may potentially be rendering two different pages.... When I check this on other sites, I'm not seeing a difference even though a redirect is in place.. (something I thought they would flag).
