On my workstation I use an SSD for the root filesystem, swapcache and

The current configuration has snapshots set to 1d (10d retention time)
and reblocking is set to 7d (1m runtime). All other option (prune,
rebalance, dedup and recopy) are disabled.

Currently it is running fine, but in my opinion running swapcache on a
workstation that just runs for a couple of hours is not always
necessary. I'm just running this setup to play with the swapcache and
the SSD, because I think it is a very nice feature.
