Re: [Dltk-dev] Performance issue

[Alex Panchenko <alex@xxxxxxxxx>]

Didier,

I have fixed the bottleneck in the folding provider.
The next integration build will be available later today.

Btw, there were some incompatible changes in the past 4 months, so you should modify you code accordingly.

Thanks for reporting this performance issue.

Regards,
Alex

Hi Alex,

With folding disabled, it works.
