Hi TeeChart Team!

We have tryed to use TeeChart 2010 code, but it's performance is significantly slowly in compare with 2009 build!

We have built TeeChart lib and our application for x86 plaform and tested it on Windows Vista (32bit) and on Windows7 (64 bit) - in both cases performance of 2010 build is low. Our application code was not changed - we only change TeeChart librarys in references of the our application project.

Unfortunately, I can't send our application source codes, but I can demonstrate performance issues in avi files, captured from my screen, for 2 versions of TeeChart - see attach.

Please pay attention on 3 actions:
1. when window is opened chart labels are moving much slowly in 2010
2. when adding new chart on - new chart label looks like stick on some places in 2010.
3. when resizing window - labels too slow moving in 2010

In common, we can see more other slow effects in drawing of charts in v2010.

We hope, you may resolve this problem ASAP.

Thank you.

Hi luzhetsky,

We've recently added some improvements in TeeChart for NET performance but I'm not sure on how will they affect your application.
I understand you cannot send us your complete application (and it wouldn't be easy to debug for us) but it would be helpful if you could arrange a simple example project where you could still notice that difference in performance.
