zfs discuss - Jun 2009 - removing large files takes a really long time

We have a 4TB pool that some files that are 50-150GB in size can take 5-10
minutes before it returns a command prompt from rm''ing a file.  Does
anyone know why this is?  Is this a bug?  We have compression turned on for the
filesystem is this a contributing factor?

What''s the version of the OS, zpool, and zfs filesystem?  There was a
bug for behavior like this when removing zvols with lots of snapshots
- maybe it''s related?
