Hi Volker, 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 63 Case2 122 119 68 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? Thanks Juan Pablo ________________________________ From: Volker Lendecke <[email protected]> To: Juan Pablo <[email protected]> Cc: Jeremy Allison <[email protected]>; [email protected] Sent: Fri, May 27, 2011 11:25:31 AM Subject: Re: [Samba] Samba performance On Fri, May 27, 2011 at 06:34:50AM -0700, Juan Pablo wrote: > Hi Volker, > > I am using the following socket options: > > socket options = TCP_NODELAY IPTOS_LOWDELAY SO_RCVBUF=65536 SO_SNDBUF=65536 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. > read raw = yes > write raw = yes > max xmit = 65535 Just remove these 3 settings. If it's still slow after that, we need to do more analysis.
