How to fix confluence performance rename page very slow?

[Deleted user]

①I create new space in confluence data center

②Upload about 3000 attachment in home page

③Create many child page 

④In child page, add new link attachment of home page

⑤In home page, i edit new page title and save page → i can't save it

In my source, if i using page manager rename then result is same. (replace link very slow)

how to fix performance when using renaming page, which multiple links?

3,000 attachments is probably the problem.  Confluence is not a file storage system, and attachments are intended to be used as supporting documents for a page (mostly images or the odd short document which the pages can render part or all of).  Pages expect to have a few attachments, maybe a few dozen (or a couple of hundred for widely shared attachments), not 3,000.

Why have you attached 3,000 files to a page?
