Lately boxing lags

Good afternoon! Fiercely lags boxing in several cases: - When I go to the "orders" page freezes, I can not scroll through the orders and go to them. - When I go to "products". At first everything works, but if you enter a product into the search, after filtering the page freezes, stops scrolling down and it is almost impossible to go to the products. Everything else works fine, other boxing applications work fine (payments, contacts, etc.). Other sites are working fine. There is no ping. Process is not loaded. There are only two problems here. Moreover, from one account on several computers. If needed, I can make a video. http://box.agro-him.com.ua/
