onebox is slow

Good afternoon. Under the accesses you specified, any page opens for me for about 3 seconds. If your communications center is buggy, try removing unnecessary notifications so that they don’t exist as they are now 100+

Good afternoon. The communications center has been cleared. Didn't give a result. Not only the communications center is buggy, but all functions. The video shows that the product was not added to the order for a very long time.
Moreover, it is not always buggy - now it opens in 5 seconds, in the middle of the day it can start to slow down. At the same time, other sites in the same browser are flying. clearing cache doesn't help

Right now I'm looking at pages for a maximum of 3 seconds opens. If at some point everything starts to blunt, then all employees of the system will blunt. http://crm.adparts.com.ua/admin/shop/statistic/ the graph shows that the load on the processor is peaking, perhaps at this moment you are launching some kind of complex action or many employees are entering the system at the same time, loading the server. In any case, I advise you to first upgrade to mvp, there it is better with performance and then monitor the situation.

Understood. I really want to update the box. Help?!
