samba - Jun 2022 - Why windows client is four times slower than linux client ?

Hi, all.

I deploy a samba server, and copy the hadoop source code to the mount
point. When I use windows client, it cost 8 minutes, and there are about 1
million packets. But when I use linux client, it cost 2 minutes, and there
are only 0.2 million packets. So it seems windows client is four times
slower than linux client. Windows and linux clients both use samba 3.1.1,
and samba server use master code. Can anyone help explain the reason ?
Thanks a lot.

Are you copying the files to the local storage of the client? If true 
maybe you should test only reading the files and not storing them 
locally after clearing any kine of cache. Windows filesystem layers are 
know to be slow when working with many small files, and source code tree 
tend to be like that.
