I have tried again and now able to write 1 million cells in less than 6 seconds. In addition, have benchmarked writing 10 million cells which takes 57 seconds on my 2.6 GHz laptop. For comparison, running serially takes 15 and 141 seconds for 1 and 10 million writes respectively.

I was curious and wanted to try again. Thus passing serial code with the same memory consumption, not 3x.

Kind regards, Mario
