BigGeoTIFF export is inacceptably slow

Description

Exporting a band-subset of one band of a CGLOPS global 300 m product (161280 x 80640) is not possible in acceptable time. I killed the process after 2 hours at a progress of 14%.

I used the export in compressed mode (-Dsnap.dataio.bigtiff.compression.type=LZW) as the data is very sparse.
CPU load was almost zero, HD activity also. I suspect some kind of thread synchronisation issue
