| Guest | Vista Copy Speed over the network is slower that XP SP2 and OSX..much slower? First and foremost..I apologize for posting to this group and the Vista General group. I think this one is more appropriate for my issue since it is network related... We have a client with a new Vista Business x64 Workstation joined to a 2003 (native) AD domain. The hardware specs are first class (64GB RAM, Dual Qaud core 3+GHz Intel Procs, Fastest SATA disks available, 2 Uber Graphics card in SLI, Giabit NIC, etc.). This machine must move large amounts of data to a File Server's SAN frequently (hundreds of gigs per upload or download). The problem is uploads and downloads to this file server via mapped drive in Vista take considerably longer than either an XP Pro SP2 or MacBook Pro from THE SAME network jack. What we have done so far with minimal improvements if any: 1. Disabled active AV scanning on the file server and removed it completely on the Vista workstation (were using Trend Micro). 2. Disabled "Remote Differential Compression". 3. Disabled SMB 2.0 via registry ***at this point the file transfer calculation seemed to start working correctly, previously it would estimate it would take 4+ hours to copy 85Gb of test data when in reality it was finished much much sooner (several minutes but forget the exact number now)*** Client reported some speed improvements at this point but not that great. From the file server during the transfer (when this is the only transfer happening on the network) the Gigabit NIC on the server reports a network utilization of 30-40%. The entire building is wired with Fiber. The file server and SAN are connected to a Black Diamond switch with a 1-2GB fiber blade. The workstation is connected to a Allied Telesyn Media converter via copper/ethernet gigabit connection (media converter routed to same fiber blade). Next week Im going to do some bench marking with different operating systems, data, connections etc. I need to find a fiber card that has Vista x64 drivers and see if that helps. Any ideas on how I can improve this transfer speed? Thanks in Advance! Sam |
