performance over network drives and folders

[UPDATE]

I can confirm that this patch doesn't fix these problems.

Searching over the network drives still very slow.

[ORIGINAL]

Hi everyone,

Sophos sent us a resolution for this known behavior.

https://community.sophos.com/kb/en-us/133001

We'll test it and let y'all know

I have a case open with Sophos too #8300032 (Dev ref:DPSGN-14511)

They've pointed me to this: community.sophos.com/.../132922

Hi Simon,

Thanks for replying. Unfortunately this KB doesn't work for us. Sophos support sent us same procedure with no success.

In our troubleshooting we saw that using native bitlocker (with no sophos installed) has same behavior as if computer is unencrypted, with excellent overall performance.

Keep on it

So you're using Sophos to manage BitLocker and you're saying this is impacting performance? Are you also using File Encryption or just full disk?

We've few laptop encrypted with sophos and bitlocker, full disk, (windows 10 1803) which is having problems loading files over network files, not just loading but even searching files.

On a testing laptop, disk encrypted with just bitlocker, everything is working fine.

We already have an opened case with Sophos Support.

Hi,

it´s hard to imagine that SafeGuard's BitLocker Management alone has an impact on the search performance on a share.
The file encryption modules (like Synchronized Encryption or Location based file encryption) however easily can. This can even be the case if you have not configured any file encryption related policies.

In a nutshell, if you don´t need file encryption capabilities you should not install these modules. If you do, it depends a bit on your usecase. For example if you don´t need to encrypt files on network shares you can configure, that the file filter driver does not attach itself there which should have a pretty positive impact on the performance. (General Settings Policy > File Encryption > Ignored Devices > check the "network" box).

Cheers

Yeah I agree it's hard to imagine that.

We will try to exclude network resources from our sophos general settings policy.


Most of users as no problems with that but only windows 10 build 1803 users.
