--- Comment #1 from Javen O'Neal <one...@apache.org> ---
Because merged regions cannot overlap without producing a corrupt document, POI
may be checking the list of merged regions on a sheet for potential
intersections before adding a merged region. This gives O(N) behavior for
adding one region instead of the expected O(1).
For XSSF and SXSSF, we added addMergedRegionUnsafe [1] that skips these checks
for speed, but may produce a corrupt document when opened in Excel. Have you
tried addMergedRegionUnsafe?
