GEOM_ELI: Encryption: AES-XTS 256 GEOM_ELI: Crypto: software That likely contributes to slowing down I/O for da0p3 and possibly to leaving less time for I/O to other partitions when da0p3 is in use. If you had the resources to test avoiding the encrypted partition for your type of media, that might prove interesting. I've never had occasion to want to use any encrypted partitions for my FreeBSD activity. I'm unsure of the GEOM_ELI processing-time contributions vs. "gstat -spod" reporting. =3D=3D=3D Mark Millard marklmi at yahoo.com
