If a PC is used by an interactive user, it is irrelevant how much access time is increased, as far as the user cannot see a difference without a timer. Several times I have read that disk encryption is not noticeable. My own experience shows that I cannot notice any difference: emacs and pine respond immediately to every key-press if I use encrypted disk or not; firefox waits for data from network the same amount of time; mplayer does not drop frames with or without disk encryption; compilation of kernel takes some noticeable time with or without encryption, but I don't know how much exactly since I spend this time in some other program. I don't want to say that the difference is irrelevant for all uses, e.g., if one edits video with 2k resolution or hosts a busy database, they can see very real difference, but such use-cases are minority and they are not done on portable computers anyway. I guess many people here have tried full disk encryption for themselves, do you notice any difference in performance or not? -- Regards, ASK --------------------------------------------------------------------- The Cryptography Mailing List Unsubscribe by sending "unsubscribe cryptography" to [EMAIL PROTECTED]
