Product loading too slow while invoicing

Product loading too slow while invoicing, suppose i type seal, it should show all product matching word (seal / seal kit / seal profile) in dropdown, but taking too long to show & when i move labtop mouse to desire one, all of them disappear, later i have to write product & price, even VAT manually, should be automatically
