    Hi everyone,

    We have a window that contains a RadRichTextBox and it is loaded on demand, we've noticed that it takes a long time to load, around 20s, the first time, after that it loads fast.

    checking on the output we found that the following module takes the entire load time.

    'XXXX.exe' (CLR v4.0.30319: XXXX.exe): Loaded 'MetadataViewProxies_09fc4bbd-18cb-4607-8b8c-a7d449e27c43'.  


    We guessed that it is related to MEF, anything on how we might fix this, by disabling probably unneeded features. Not all features are needed for our case.

    we are using the following version: 2013.3.1016.40

    Regards

    Hi Abdelkarim,

    Thank you for getting to us with this!

    The initial loading time of RadRichTextBox is influenced by its usage of MEF which is used to load extensible components like the format providers and UI widgets. This can be slow in some situations and you can improve the startup time by changing the default catalog used by MEF as described in this help article.

    We are currently planning performance improvements on some areas of the control and we will do our best to release them as soon as possible. 

    Also, please take a look at this help article about performance in RadRichTextBox.

    I hope this helps! Let me know if you have other comments or questions.
