creation of home folders: race condition during login phase

Description

We have a site that has a lots of documents (wrongly set up with DirectoryStorage? + ext3 ...). It is going to be migrated to DS + reiserfs.

However, the creation of a new folders can take between 10 to 15 seconds...

It means that when a user logs in for the first time, the home folder has not necessarily been created when the logged_in.pt page is reached. And the user immediately gets logged out.

the current implementations assumes that the creation a new folder takes less than the time needed to fulfill the login request, which probably is true for most sites, though..

10 seconds to create an object is a big performance problem! Why does folder creation take so long? Have you profiled ? DeadlockDebugger? could give simple ideas, or ZopeProfiler? could tell for sure.
