Before I forget - the files used for to gather these runtime numbers, posted in an earlier email, are found here: https://gerrit.libreoffice.org/#/admin/projects/benchmark
There are five xls files with an explanation as to what the spreadsheet is evaluating. They are 4 years old and seem to be as good as I've found for example files to show the multi-core threading feature. Seems to me it might be worthwhile to offer them for download (maybe as a zip file) and reference that download location in the video and/or associated posting text. Also, yesterday I went back and reviewed a number of the blog posts and a few media posts regarding threading (OpenCL and Multi-Core), thought that was a good first step in writing up a script for use here. Have also gone through the Calc Functions list, as supplied in the Calc Guide (updating it from 4.1 - 6.2) and have marked which functions are thread enabled and which are not - not sure I have an exhaustive list but should be close if not there. That is not really a marketing issue but in a marketing piece listing the categories of statistical functions supporting the feature seems to make sense. OK - that's it for this email.
