low upload speed for SCP/SFTP even PUT to TCP 22 when MPLS IP configured

Hey guys, we are experiencing the low speed for SCP/SFTP even PUT when we upload file to the server in our network.

And this issue only happens if the server TCP port set as 22. We are an ISP network and do not set up any limit for TCP port. 

The issue only happens when UPLOAD action happens. For example, if from the server using GET or Download a file, there is no issue(the same direction).

 

The topology like this below

Client - ASR920 - ASR9001 - Internet(server)

All network running MPLS LDP

After multiple tests, if we remove the "mpls ip" under the interface in ASR920 faces ASR9001, the issue gone.

The issue both happens in IOS-XE 3.16/3.18/16.9.4. 

Anyone have any idea about that?

 

Cheers

Charles
