I can't speak to this issue in regards to OpenIndiana but CIFS/samba has historically been much slower than NFS, FTP, and even netatalk, etc. due to its large metadata overhead. One can observe this in the wild with a few well time tcpdumps. One thing that might be worth investigating in this

[OpenIndiana-discuss] poor performance scaling when deploying shared zfs filesystems.

I had a bug filed with Sun on Opensolaris long ago (CR 6850837 , P2 utility/filesharing libshare enhancements to address performance and scalability) and I thought I try OI to see if anything had improved with recent builds. I am trying to deploy around 6000 filesystems across 3 pools. Each pool

Oh, good point. Not sure what is going on then. My win7-64 box has realtek NIC, and perf is fine with everything but CIFS. The centos box also has realtek, IIRC. Odd... -Original Message- From: Eric D. Mudama [mailto:edmud...@bounceswoosh.org] Sent: Thursday, April 21, 2011 7:23 PM

An intel pro/1000, unfortunately, it'll be a pain to try it. The centos box has no pci slots. I'll have to pull my win7 box open and try it there. Stay tuned... -Original Message- From: Gregory Youngblood [mailto:greg...@youngblood.me] Sent: Thursday, April 21, 2011 11:05 PM To:

Did both the CentOS and Windows boxes have realtek cards? I don't know if I missed that detail earlier. I don't know that it will make much of a difference, though in the past I do know that realtek cards had issues and sometimes wouldn't perform very well. These days I pretty much stick with
