Hi Team,

I've been trying to make the Samba performance test tool work against

After a lot of effort, Garming and I fixed all the errors for different
packets, and finally it's working(fixes are merged into master).

Base on that, we can send traffic to Samba and Windows, get the maximum
load, and compare the performance.

An example of the command I was using:

script/traffic_replay -U Administrator%PASSWORD  --realm krb.samba.site
--workgroup KRB --fixed-password FIXED-PASSWORD -r 4 -S 4
traffic-sample-1-model.txt dc1.krb.samba.site 2>&1 >

By changing the combination of different -r and -S, we can get test
results and save to files, then parse files to get summary tables as below.

The number displayed is "*Successful operations per s**econd*", the 0
ones are combinations we think not important and skipped.

      Test Result for Samba (master code on 2018.05.11):

      Test Result for Windows Server 2012r2:

I am running the test with 4 servers in Catalyst Cloud which is Openstack:

All data are attached, hope this can help the team to understand how is
Samba performing with compare to Windows.
