Hello,

One of my customers is planning to enable SMB Signing for their SCCM infrastructure, and there are concerns when it comes to performance. We realize that SMB is used for a variety of communication among the systems involved:

Also, it is a Best Practice to use either IPsec or SMB signed traffic to protect communication channels:

Do you have any expierence on the performance impact and things to watch out for?

Thanks

Using SMB packet signing can degrade performance up to 15 percent on file service transactions.

Depending on your network and your storage system implementation, the performance impact might be quite different. You may have to test in you own environment to get an accurate statistics.
