6x times faster processing performance with SNAP

[Marco_EOM]

Is SNAP processing too slow? This GPF Runner might help you.

I’ve observed that GPF is sometimes slower when using the gpt tool compared to a small main method which uses the API directly.
I have reported about this issue before here in the forum:

Odd processing performance

Dears, I have made off observations of the processing performance. I know that these are not new, and actions have been taken to optimise it. And progress was made. But still in some situations the processing performance is strange. The issue cannot be the memory. I’ve used 20GB for the process. and during the process the limit wasn’t hit. First, I observed unexplainable slowness for a specific data format when processing with my current operator under development. Observing this, analysing …

Now I’ve prepared a little tool which can make your processing up to 6x faster. It does not work for all cases, but before starting a mass production it is worth to try it.
