Slow samba in Text mode [11.3]

Hello there,
I have problem with samba on my home server running on 11.3. When I choose full instalation with GUI (KDE), everything is all right, samba trasnfers reach full speed of my 100Mbit ethernet (approx. 11,5 MBps, unfortunately I can’t test 1Gbit).

But when I choose instalation only with server text mode, samba speed decrases to level of 1,2 MBps on upload (write TO server) and 0,8 MBps download (read FROM server). Same situation is, when I install full desktop with KDE, but I disable X in Run levels over Yast.

Can anybody help me?

Thanks.

could you show your smb.conf files on both systems?
