Slowly works in Safari

Hello!

My site works well in all browsers except Safari. The page loads very slowly. How can I fix it?
I updated the latest Sydney theme and clear all caches. But nothing helps to fix this problem.

Hello there,

Which version of Safari are you running? Is it the latest one?

Regards,
Kharis
