Help to analyse wireshark output from a site with PCs that are slow to load a website

Pls refer to the other EE article at link below as this question is
a further follow-up to it:

I've run Wireshark on the user's PC that's slow to load a website
(& all its related pages) but this only happens to this remote site's
PCs while all other sites loads the same website in less than 1 sec.

I sorted the Wireshark output with the longest timings' items at the
top.

Any clue that this wireshark reveals that could help explain the slow
loading of the page?  The wireshark starts capturing about 1-2 secs
before I hit ENTER to load the web page

you are better off using a tool like Fiddler to diagnose slow performance on a website than wireshark. The wireshark trace can be a useful back up to the fiddler data but fiddler will give a better view

It looks like you may have an MTU issue or a framing issue on the WAN Link,  what are the components of the link to the remote site?

Do you have other networking between the sites such as AD and file sharing?

I've been using Fiddler & httpwatch: yes the outputs are much
friendlier but no resolution troubleshooting with these.

There's no AD & File sharing between the sites
