Very slow performence (pagination, bluk action)

Hello, I'm facing a problem regarding the panel performance in all resources. So, when I try to display all records is taking so mush time, and also when I select all records for bluk action. For example, the endpoint belongs to many domains. I displayed the domains in a relation manager table in endpoint view page. This endpoint has 2,000 domains, so when I tried to display all records, it took more than 40 seconds to finish. I would really appreciate it if anyone could provide ideas to improve the panel's performance.
