Without GELI I can get to almost 10MB/s (Fast Ethernet wire speed). But when GELI is on the way, 3MB/s is never reached. well, I don't want to have a gigabit wire speed encrypted file server. All I want is to look for the ways to make mine as fast as it can be. If 2MB/s is the fastest it can go, then I'll see if it is enough or not. I just need to make sure I'm in the fastest config possible. I got to see that Via Padlock and their site says is really fast (wouldn't they ?!), so I'm trying to get a board from them to see it myself. But first I need to get rid of the atom board, as this is my home, I can't have so many machines :) thanks for all, matheus >> thanks, >> >> matheus >> >> machine: >> ACPI Error: A valid RSDP was not found (20110527/tbxfroot-237) >> Copyright (c) 1992-2012 The FreeBSD Project. >> Copyright (c) 1979, 1980, 1983, 1986, 1988, 1989, 1991, 1992, 1993, 1994 >> The Regents of the University of California.
