Plugindev - How can I nail down performanceprobs with MePo 1.2 svn in facadeloading? (1 Viewer)

[Guzzi]

Hi devs,
I am working on the MyFilms plugin and have encountered a performanceproblem, when gpoing from MePo 1.1.1 to 1.2 svn.
The initial load of a very long list takes approx 20 seconds - in comparison 1-2 seconds with MePo 1.1.1.
Beside some GUIcontrol stuff, there is only 2 things using MePo code, where I see there were changes done:
1.) if (!System.IO.File.Exists(conf.FileImage)) ...
2.) strThumb = MediaPortal.Util.Utils.GetCoverArtName(Thumbs.MovieTitle, sTitle);
Can you give me a hint how I can get back to 1.1.1 performance in loading the facade?

Do I have to change handling - e.g. regarding the Fileaccesscaching introduced or access to Utils classes?

Is there a free profiler available I could use to find the timeconsuming parts of the code?

THanks in advance for your help,

Guzzi

ok, I digged a bit by myself and ran the following tests:
Test 1:
Running MePo 1.1.1, loading, entering plugin into listfacadeview, changed view to reload listfacade, the latter is done by GetFilmList() - time for this is 3,02 seconds.
Test 2:
Running MePo 1.2 with SVN from 15.11., same procedere, Runtime is 157 seconds
Both test are Debugbuilds - without profiler and in release both runtimes are about the half.

So running in 1.2 gives me 50 times the processingtime than 1.1.1.

I have attached screenshots of the profiling.

Further I noticed, that in 1.2 after 1st loading of the facade when the GUI is rendered, I get lot's of DirectX exceptions in DoRender() - what could be the cause for this? Don't have this in 1.1.1

Further questions:
The (newly introduced) caching seems to spend much more time for what it does than it saves ?
There seems quite a lot of time to be spend with coverflowstuff in 1.2 - is this intensional or a bug in the plugin?

Screenshots for Test 1 - V1.1.1 runtimeenvironment:

Would very much appreciate, if you could pinpoint me, if there is maybe something wrong on pluginside, that I could fix.

Thanks, Guzzi

ok, actually it's the GUIFacadeControl.Add() Call that uses the extra time with coverflow - all other types are very fast:



Maybe it's possible to not filly load the anymations when just adding to the facade?
filmstrip is initialized as well and is fast...

Any help?
