Re: [Dltk-dev] Performance issue

["Jae Gangemi" <jgangemi@xxxxxxxxx>]

  i've noticed this as well - one of the issues w/ the folding is that it reparses the source module directly instead of using the SourceParserUtils class (i think that's it, i'm not looking at the code) that will check the cache and use that ModuleDeclaration object if it exists.

  i have been looking into fixing this, but have been tied up with things at the day job lately.

Didier,

It looks like the folding code is slow on large files.
Would you please check how it works for you with disabled folding?

There were several optimizations recently, but it looks like additional efforts are required.

Alex

Yes, it is CPU time.

I use the profiler included in Eclipse Ganymede.

I am not able to generate other statistics due to amount of time it takes.
After two hours, I have forgiven.

There are two files in the project. A small one 29K and a big one 2M.
When I remove the big one the performance problem disappear.

I used DLTK 1.0.0.v20080815
