Why does the site take a long time to load on smart?

Question

css

Hello, there is an ancient site on Modx. When I go to it from a PC, everything is ok. When I go through wi-fi from smart - 14-15 seconds are loaded. There is no js on the site, there is not even a separate css file, there are 5 pictures on the whole page. But the whole page is made in tabular layout (table td tr). The total weight of the page is 50 kilobytes. I went through it with different analyzers: All give out 70 - 100. But on smarts everything is very bad. What is it for?

Answer 1

Smarts are different and they have browsers too. As an option, try to connect smart by wire and check the site loading speed.

Answer 2

Measure with Google Page Speed ​​or Pingdom for example to get started. figures are needed for further analysis.
