Title: [TECH-SUPPORT] LPS-43399 Concurrent file upload/update/deletion in Document library portlet is slow due to row lock contention

Hi @shuyangzhou

I'm sending @laszlocsontos' PR. This is a performance issue fix for lastPostDate update. Based on the Document Library logic I think there's no negative effect if we update that date in an asynchronous way.

Please review this PR and let us know if you have any concerns.

Regards,
Vilmos
