Sophos Endpoint Intercept X 2.0 impacting Performance - slow?

On a new software build of windows 10 on a T450 Lenovo, we found that at the end we installed Sophos Endpoint Intercept X 2.0 and it significantly slowed down the computer.  All aspects of the computer became slow.  On first bootup, connecting the Wifi - slow.  On login, the CPU would pin at 100% for long periods of time with high memory usage.  All applications would be slow to open, printing would be very slow. This is a new laptop i5, 8 GB RAM, 256 SSD.

We would remove the Intercept X and the computer would return to normal operation.  Fast bootup, fast login, apps, etc...

Now for this customer, then use Trend Micro as their primary AV.  We have Sophos Intercept X added on for the extra protection. We did not have issues previously until the Intercept X Version went up to 2.0.  Has anyone else noticed a large performance hit with Intercept X 2.0?

  • We are experiencing something similar with some of our notebooks.

    We are using the following system:

    • HP EliteBook x360 1030 G2 - most recent hardware
    • Windows 10 Pro Build 15063
    • Sophos Software:
      • Core Agent: 2.0.0
      • Endpoint Advanced: 10.8.1.1
      • Intercept X: 2.0.1
      • Device Encryption: 1.3.90

    Like Stephen described, the client boots slowly. Once the login lock screen of Windows 10 shows up (which takes forever compared to pre Intercept X 2.0), it takes quite a while until the actual login form shows up. Other symptoms as described before are also present.

    Our current workaround is: 

    1. Uninstall Intercept X - not a nice solutions since we would love to be using Intercept X
    2. Delay the autostart of the MCS Client Service. Just as precaution, because in the past Sophos had some performance troubles with this service on startup.

    This workaround doesn't solve the problem, but it makes it bearable so the users can actually work on the devices.

    Would love to see a fix for this.

  • I am also experiencing this issue with Sophos.  Windows is also very slow to login, opening applications like Chrome and Outlook are painfully slow.  Programs are also very slow to respond and will often hang.  

    We are running: 

    Core Agent 2.0.0

    Endpoint Standard 10.8.1.1

    Sophos Intercept X 2.0.1
