Snappy running really slow

[M_Iaco]

I had a similar issue. The problem seems to be with the writeProduct function being slow.
I went from about 6 minutes writing time (on a monster machine) to 10-30 second by following the advice given here:

Performance of snap desktop and snappy

There could be two reasons. One is that you have worked with the data in the desktop already and the data is already computed when you write the data. But I guess this is not the full story. Instead of ProductIO.writeProduct() you can try the Write operator with GPF.createProduct(). Specify the file and the formatName as parameter. [image]
