  LPS-975	Dock takes a long time to render if there's a large number of org/community
  LPS-24728	Deleting pages takes a long time
  LPS-23660	Deleting more than 2000 files takes longer than 15 minutes
  LPS-32000	Create large number of users through Liferay API we get an error saying "Too many open files"
  LPS-5573	Download pop-up box takes too long to appear

Steps to reproduce:

1. Add a large number of files to the document library (>>1000).
2. Delete the files. Deleting the files takes a significant amount of time.

Preliminary tests show the following:

Delete of 1000 files took 0:00:31.918
Delete of 2000 files took 0:01:01.594
Delete of 3000 files took 0:02:04.556
Delete of 4000 files took 0:03:38.619
Delete of 5000 files took 0:07:01.596

While the earlier fix of LPS-23660 seemed to solve the initial problem, the codebase seems to have regressed and is not performing as well as before.

Can not reproduce on:
Tomcat 7.0 + MySQL 5. Portal 6.1.x EE GIT ID: 62c55afdd9ff2bd7067dee314ef57f65039d862f.
Tomcat 7.0 + MySQL 5. Portal 6.1.x CE GIT ID: 78eb221407070614ff8bf6571f0b898dcfba520f.
Tomcat 7.0 + MySQL 5. Portal 6.2.x GIT ID: a9a6914a00a311aeee4b87efc6e9f2c19cd5cb7d.

I delete >>1000 file, use 30-40 seconds, So I think this is not a bug.
