Receive Side Scaling (RSS) – enabled by default on Win 7 & 2008R2 – disable it, and your problems will likely go away. It causes even worse problems on servers with NIC teaming.

Based on other chatter I have come across, these are likely associated to known issues/settings in Windows 7 that can be disabled. Verify the transfer time-to-transfer complaint first. Make sure to take into account locally available resources and system use. -- Espi On Tue, Mar 6, 2012 at 11:08 AM, Richard McClary <[email protected]<mailto:[email protected]>> wrote: Greetings! Our DBA created a backup system for our DB2 databases where a VM (running DB2 for the tools) would back up our medical records database (on another server), create ZIP files (the zip script was set to create zip files from the database backup in 4 Gb chunks), then copy those chunks to a user’s desktop PC. The principle user of that PC would then burn the ZIP files onto DVDs for storage. The zip files total a bit over 5 Gb. Back when the “target PC” was my own, I had a Dell PWS-390 running XP Pro SP3, 32-bit. The “target PC” is now an Optiplex 990 running Windows 7 Pro, 64-bit. Our DBA says the copy from the backup system to the “target PC” seems to take twice as long copying to the Win 7 machine than it did to the Win XP machine. Any ideas as to what might be slowing down the copy process? (FWIW, the motherboard on that PWS-390 failed a couple of months back, so a side-by-side test would require scrounging up a still-functional PWS-390, installing XP, etc.) Thanks! -- richard -- Richard D.
