What Operations are Single Threaded

Hi All,

 

We are performance tuning our Qlik Sense environment and something I keep coming across in Qlik Documents and Blog posts is that some operations in Qlik are single threaded which can max out CPU and deteriorate performance. I was wondering if there is a definitive list of functions or operations in Qlik that are single threaded so we can identify any and improve upon them.  For example I have seen that Group By's in the script are single threaded (was posted in 2014 does anyone know if this is still the case).

Thanks,

Mark

I don't have a full list, but I know rank() is single threaded.
