That's strange indeed. I just replaced 21 drives (seven 2TB drives in three raidz2 VDEVs) drives with 3TB ones, and resilver times were quite stable, until the last replace, which was a bit faster. Have you checked 'iostat -en'? If one (or more) of the drives are having i/o errors, that may slow down the whole pool.
