Description (last modified by bramalingam)
ref: https://www.openmicroscopy.org/community/viewtopic.php?f=4&t=7886
Performance issue noticed in the way Bio-Formats scans and reads the tiles.
The tiles are stored as horizontal strips that span the entire width of the image, but the current implementation in Bio-Formats reads 4 strips at a time, to generate the tiles in OMERO. This leads to repetitive reading of the strips to generate the tiles across the image.
