Incredibly slow boot speeds using Sophos Encyrption

indiefantv

We are running Dell Latitude E6410 laptops with 3gb of memory and Intel i5 processors running at 2.40Ghz. We have 7200 RPM 300gb drives. We are running Windows 7.

After encrypting with Sophos Safeguard the laptops are extremely slow - some may take in excess of 15 minutes to boot. The laptop will get to the Sophos screen then go to a blank black screen and do nothing for at least several minutes. During that time the hard drive light will be lit solid. Even after getting to the Windows 7 login screen you will have to wait there for several more minutes with the hard drive light lit before you can even login.

Does anyone have some suggestions on might be causing the issue? This is a major issue for us that is effecting many people in our office.

    Hi Indiefantv,

    15 minute boot time is quite unexpected. On a plain E6410 with only SafeGuard Enterprise 5.6 / 6.0 encryption installed, I'd say that the boot time should be about two to max(!) five minutes - depending on the hardware used (i3/i5/i7, SSD vs HDD etc..).

    Like mentioned before I'd check if the machine is equipped with the correct and up to date drivers. Also can you determine where the machine consumes the most of the 15 minutes boot up time (pre-POA, post-POA boot, Windows Boot up, actual Windows Login or on the Desktop when loadin the rest of the installed applications)?

    SafeGuard version 6 compared to version 5.x has major performance improvements. Most of those can be noticed if the machine is equipped with hardware/CPUs that supports AES-NI. Here's a c&p from one of my other post regarding SGN 6 vs 5.60 speed and SSD recommendations:

    "SafeGuard Device Encryption, as of version 6, uses hardware-accelerated AES on computers equipped with a CPU that supports Intel AES-NI (AES - New Instructions) to improve performance and user experience. This option is automatically checked and enabled by default - which might be the reason for the performance improvements you see compared to version 5.60.x.  :smileyhappy:

    Please note that the full disk encryption of solid-state drives should always be accomplished using SafeGuard Enterprise' Fast Initial Encryption feature.
