IdePix together with Resampling (60m) in a graph slows done processing drastically

[marpet]

When using the snap_idepix_c2rcc_sentinel2_operator.xml graph, the processing does not end or might even fail with a memory error. At this happens even when using only 60m resolution.
Some tests have been performed:

• When splitting it into two steps, each processing step is finished in about a minute.
  • snap_idepix_c2rcc_sentinel2_operator_step1.xml
  • snap_idepix_c2rcc_sentinel2_operator_step2.xml
• When replacing the S2Resampling operator with the generic resample operator the problem persists.
• When removing the C2RCC the problem persists.
• When removing the IdePix operator the performance is good.

So, the culprit seems to be IdePix. Or the problem is SNAP and how it is manging the data. But other operators perform better.
