want a histogram of compressed block sizes
zfs - Zettabyte File System
From Matt Ahrens's original bug report at Delphix. It describes our main use case, but the functionality could be more generally useful for inspecting pools.
zdb should be able to output a histogram of compressed block sizes. We will run this on a customer system and use the results to create blocks of representative sizes when aging a pool for performance testing.
