So I turned deduplication on on my staging FS (the one that gets mounted

Does it have enough (really, lots) of memory? Do you have an l2arc
cache device attached (as well)?
The OP said he had 8GB of RAM, and I suspect that a cheap SSD in the 40-60GB
range for L2ARC would actually be the best choice to speed things up in the
future, rather than add another 8GB of RAM.
I think I'm going to try both. Easier to get one request for upgrades approved
than get a second one approved if the first one doesn't cut it.
