Whoops, I guess I didn't reply correctly and accidentally created a new thread with my response, so here's to hoping I get it right this time...
> What Version of Samba is running? Various versions of 3.0 on multiple servers. > Is it a kind of Locking Problem? Ooh, good question, I'm not sure, and I'll try your oplocks settings. What exactly am I turning off, however, if I do that? Am I turning off file locking altogether? > What speed have a Filetransfer with ftp? > What speed did you have with a Windows Server? Ok well along those lines, here's another thing that I've noticed since I first posted. I had been getting ~940Mb/s in iperf, so I didn't think it was a network or NIC specific issue. I was using "mount -t cifs" and "rsync -a --stats --progress" to gauge my speed, which is where I was getting the <20 MB/s speed statistics. However, copying large files through Windows Explorer from the Samba share results in 55-60 MB/s. So, I don't know if there's a problem with rsync, smbfs, or cifs or whatever, but it looks like actual file transfer speeds (whether on one large file or an entire directory) are pretty good. I wouldn't mind seeing closer to 100+ MB/s, but I guess at around 60 MB/s, that's a great start. NOW the problem is that whenever I actually OPEN a file from any of the Samba servers, it opens MUCH slower than on a comparable Windows server. A large Excel file, for example, takes 15 seconds to load instead of 6 seconds when loaded from the Windows server. A given FoxPro query takes 45-55 seconds to run over the Samba share as opposed to around 10-12 seconds over the network from the Windows server. Could this be related to the oplocks stuff you were talking about, or would this point to a completely different problem? What are the downsides to turning off these oplocks settings? >Have you testet your Diskthrouput with bonnie (or such Tools)? Yes, and I'm getting at least 50-60 MB/s (probably now my bottleneck), although I've set up an SAS raid array that ought to get much faster than that, but doesn't - however that's a question for another mailing list!
