@sualko thank you for your help.
Do you use it in your own phpCode or in typscript/template.
Could you share some example?
Does anyone know a way to output cache-data, or maybe there is an exist helper? Like:
##use in template
<f:debug cacheData=true>{nodeType}</f:debug>
##resulting sourceCode something like this
...
<div class="neos-nodeTypeXY">this is an simple textContent or something really complicated</div>
<!-- f-debug-cache-info: cached at: 1468845240 unixtime, CacheFileIndentifier: blublu12234blabla -->
