Slow CIFS, Fast SCP
862854May 18 2011 — edited May 21 2011Hi,
My system is Solaris 11 Express, and I am seeing transfer speed of 40 MB/s over scp, but I get 10 MB/s over CIFS. Over gigabit I've tried Windows 2003, XP, Windows 7, and Ubuntu clients. All achieve the same 10 MB/s over CIFS. I do an scp of the same files from my Solaris machine to my Ubuntu machine and I get 40 MB/s. CIFS is setup as joined to my Windows 2003 domain, but I tried switching to workgroup and got the same results. I initially thought it was my raidz1, but I get the same transfer from my single boot disk. I notice the CPU usage is at 50% or more when transferring files over CIFS as well.
I've searched high and low for information, but I can't find anything to help me fix the problem. If anyone can offer ideas or direct in troubleshooting measures I would greatly appreciate it.
Thanks,
-Nelson

You are discussing a system that you've installed Solaris 11 Express onto.
I deleted your duplicate post that was in the Solaris 10 subforum.
Let's leave this one here in the Solaris 11 subforum, where it is on-topic.
