It is necessary to optimize the server and the operation of the CRM

Faced with the problem that with an increase in the number of employees, orders, etc. Some actions started taking much longer than usual For example https://vzutik.crm-onebox.com/admin/shop/statistic/ Minute action works 25 minutes [file]6090[/file] And the hour is more than an hour [file]6091[/file] And sometimes it doesn't start at all [file]6092[/file] Because of this, prices are not generated on time, order statuses are also changed at the wrong time, and a lot of other problems that are associated with this. Tell me, who can see what the problem is, give some recommendations on optimizing the server, maybe you need to clean something, etc.? At least that the minute handlers worked faster than once every 20 minutes, and the hour ones worked stably. How much is it ?
