Hi Linda, thanks a lot for sharing your params; IMHO it's very useful to them in combination (Win registry, Samba config, Linux sysctls). Would you mind telling us a bit about your client and server HW, the Samba server OS and version you use so that your test results obtained with dd appear in

I can share what I have, but won't claim they are optimal for everyone. For win7, they give near theoretical performance on writes (with win7 tuned correctly as well). Will only mention a few pertinent items. Standard disclaimers concerning your software, work load and hardware all need to
