(i386 7-STABLE) Swap on a dedicated slice. Some Z Filesystems used compression (/usr/ports, /usr/src, for example). I encountered several crashes, especially during heavy loads, such as compiling big ports. Tried some of the "workarounds" listed on the page, which decreased the performance to a level where watching HD videos wasn't possible anymore. On heavy load the system was unable to perform as expected, leading to side effects like a stuttering mouse. All this disappeared since I switched to classic UFS. My home server is a amd64 7-STABLE, 4GB RAM, 4x400GB HDD with geli encryption (AES 256). This works like a charm. So my take on ZFS is that it is a no go on i386, but a stable solution on amd64.
