[Samba] Samba performance

I've removed the SO_RCVBUF=65536 SO_SNDBUF=65536 and the 3 other setting,
reloaded samba and repeated the tests but still getting the same results for the
local tests and also from Windows.
I am getting the following results in MBytes/s:
Test type Local (dd) Local (smbclient) Window 7
Case1 161 101
Case2 122 119
Case1: Read 1000 files 8 MByte each
Case2: 4 processes each reading 1000 files of 8 MByte each
Any idea how can I debug where the bottleneck is or why I get so low numbers
when reading from Windows?

Just remove the SO_RCVBUF=65536 SO_SNDBUF=65536 settings.
Unless you're on a very old Linux or other Unix the kernel
is far better off figuring out that itself.

Just remove these 3 settings. If it's still slow after that,
we need to do more analysis.
