IDEA RE-indexing speed

Hi All!

Here is several questions related to IDEA indexing which are interesting for me:

How often idea rebuilding whole project?
How long it takes to rebuild it in average?
Why do you think rebuild triggered?

Looking forward on community members answers, thank you in advance.

Hello Dmitry,

There is no reason to guess the answers. A whole project rebuild is performed
in case of abnormal shutdown of IDEA (VM crash for example) or in the case
when a plugin that provides its own indexes (for example, Ruby or Python)
is installed or uninstalled. A rebuild in any other case is a bug. The reason
for a rebuild is always written in idea.log.

May be it sounds wrong, but I mean "quite long project (re-)indexing without any major changes in the project"

P.S. Dmitry, please check your Wave account for some thoughts on this topic. This posting is kind of quiz to figure out some fact.

In particular now, when project building externally it takes at least 30 seconds to reindex sources, but in fact only one class was changed for example. Actuall many sources is generated by Ant but it is generating THE SAME files each time.

I always assumed that installing a new IDEA build also triggers a rebuild. Isn't it the case? It surely seemed so to me.
