[cdt-dev] Performance issues with indexer/refresh on large scale project
|
Hi
all,
I'm running into
serious performance problems with a ~40k files C++ project (standard make
project on Solaris/Sparc with ClearCase as SCC). Importing and indexing the
project takes hours, which is at least partly caused by a lot of unnecessary
files being opened.
Three questions:
* How can I
programmatically disable the automatic indexing for a period of time,
and reenable it later (I found that it's faster to do a refresh without the
indexer running, and doing a full indexer run afterwards)? I'd try to do that in
a startup plugin, which would disable indexing, import the project, refresh
everything, then run the indexer. Maybe that could speed up
things...
* I would like to
exclude a complete part of the project hierarchy from being seen by Eclipse and
CDT. I thought the "filter" setting ("Source folder exclusion pattern") on the
CDT source folders property page would do just that, but no. I excluded the
"test/" folder and some others with the filter, now it is no longer shown
in the project explorer. But monitoring the system with Solaris dtrace
shows that the whole <projectroot>/test folder hierarchy is still
scanned (stat system call) during a refresh, and a lot of files there even get
opened (Imakefiles, *.txt, *.xml). This is quite bad, as it contains 20k files
that are only testcases and data stuff. Anything I can do?
* Is there any
general guideline for setting up such a large scale project with CDT,
anywhere?
Thanks!
Achim
