[Samba] Why windows client is four times slower than linux client ?

[jie wang]

Thanks the reply, I'm not copying the files to the local storage of the
client. There are 3 computers, samba server, windows client and linux
client, and copy files from windows/linux client to samba server's storage.
The network latency is almost same between windows client -> samba server
and linux client -> samba server.
