Sorry for the late reply. I just tried the new version (thanks for compiling, stas :) ) and it works now: glxsb0: <AMD Geode LX Security Block (AES-128-CBC, RNG)> mem 0xefff4000-0xe= fff7fff irq 9 at device 1.2 on pci0 moe:~# geli list Geom name: mirror/dataraid1.eli EncryptionAlgorithm: AES-CBC KeyLength: 128 Crypto: hardware [...] But the speed is the same. I still only get ~1.2MB/s transfer speed over the net. However, this doesn't seem to be related to geli. The cpu is pretty much idling: last pid: 2769; load averages: 0.06, 0.10, 0.08 up 0+00:18:04 12:23:07 39 processes: 1 running, 38 sleeping CPU: 0.8% user, 0.0% nice, 16.7% system, 9.3% interrupt, 73.2% idle Mem: 25M Active, 100M Inact, 35M Wired, 6192K Cache, 27M Buf, 588K Free Anyways, thank you for your work on backporting the driver, Patrick! :) Lars --Z9t8O/5YJLB6LEUl Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.9 (FreeBSD) iEYEARECAAYFAkmf5QYACgkQKc512sD3afjLkgCfQ1msHoIjCNxsqpM23ha5OPwi /IkAnR+nMoLHn50vfHnGNKNmlO+tcVjf =yXhr -----END PGP SIGNATURE----- --Z9t8O/5YJLB6LEUl--
