Performance impact of SMB Signing

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
