A missing synchronisation in the WriteCache can cause that data is not correctly written. Mostly some data is missing (zero values) in the first bands which are processed.
Does the fix affect performance? Obviously the data needs to be written to disk correctly and efficiently…
It might cause a minor performance drop, but this should not be significant. It is more important that the data is correct.
We want to release a module update soon.
Of course the data has to be correct, but please verify the performance too.
Performance graph on the test server is still green
