quick question about Target First Byte Time

[Smoi]

Hi,

I have run the test on a complex page of my website and Target First Byte Time is around 600ms and my First By Time is around 1600ms, fine by me, there's room for improvements.

I have run the test on a direct url of a simple image of my website and my First By Time is around 800ms (again, improvements required) while my Target First Byte Time is still around 600ms.

I find this intriguing, is the Target First Byte Time really the same for a complex page and for just an image ?

The target first byte time is round trips for connection/request + 100ms (basically a 100ms budget for back-end complexity). It is usually meant for pages (regardless of complexity) since static content can usually be served even faster.

ok, thank you

So different hosting in the same country with same website could have a different target first byte time?
