SAP production Server gets very slow after installing sophos Server protection

one of our clients SAP production Server gets very slow after installing sophos Server protection and users always experience sluggishness when trying to access the SAP server. The server gets back to Normal after sophos is uninstalled from it . anyone else experiencing this??

    Do you know what helps solve the problem without removing Sophos, for exampke policy changes?

    For example.  If you exclude the drives from real time scanning, E.g. C: D:, etc.. does it work as expected? If so, that suggests exclusions could help.

    If it is a file based "problem" then you could run Process Monitor and see what files are being accessed so often to cause an issue and narrow it down further.  You can add the duration column to help identify files taking a while to read/write.  0.1 seconds and greater might be a good starting point.

    OK, It sounds like the traditional real-time scanning may not be the cause or at least the full cause if you haven't seen a full improvement.

    The next step would be to consider the features such as CryptoGuard and exploit prevention.  I don't know how easy it is to restart the server but a quick way to rule these features out is to rename:

    \windows\system32\drivers\hmpalert.sys

    to say 

    \windows\system32\drivers\hmpalert.sys.off

    and reboot. 

    This will disable the CryptoGuard features in the driver and also prevent the driver from injecting the hmaplert.dll into processes for exploit prevention.

    If the issues goes away without the driver loaded, at least we have identified the component, before breaking it down further.  

    The next option would be (after re-renaming the driver back and rebooting) to split CryptoGuard and exploit prevention features.  CryptoGuard can be disabled via policy.  High level Exploit prevention features can also.

    I hope this strategy helps identify the cause.
