Woeful LAN Performance under Win 7
in [64 Bits Windows]
|
From: Jim Henriksen on 21 Jan 2010 14:45 I have a small wireless LAN at home. I'm running XP-32 on a desktop machine and Windows 7-64 (Home Premium Edition) on a laptop. Here's what I'm trying to do: 1. From the laptop, I use the Explorer to bring up a directory tree (across the LAN) on the desktop machine. 2. I select 2-3 files I'd like to transfer from the desktop machine to the laptop. The files are 1-2 MB in size. 3. I right click on the group of selected files. At this point, there's a long pause and a flurry of activity on the wireless LAN. It appears as though Win 7 is reading all the selected files. 4. I then click "Copy." 5. Using the Explorer, I select a directory on the laptop machine, right click, and click "Paste" in the dialog that appears. 6. There's another long pause as Win 7 appears to be reading the selected files again. The dialog that appears on the screen indicates that files are being "discovered." 7. Finally, the copy begins, and Win 7 appears to be reading the files for a third time, which is s-l-o-w. 8. If I'm overwriting existing copies of the transferred files, the progress bar for the copy operation turns red, and about 15 seconds later, a prompt appears, asking me whether I want to overwrite the existing copies, etc. All together, selecting and copying 2-3 files whose sizes are on the order of 1-2 MB takes several minutes, which is pretty wretched. Did MS really do such a lousy job of implementing mixed operating system networking, or am I missing an option or two that can speed things up? TIA.

Vista and Winn 7 introduced some networking "optimizations" which may not always inter-operate nicely. Performance improves when all components (switches, routers, other computers) support those enhancements. Performance drops badly if something doesn't support the enhancements. This link doesn't really explain much, but does include commands you can try to disable the "enhancements" in Win7: http://blogs.technet.com/networking/archive/2008/11/14/the-effect-of-tcp-chimney-offload-on-viewing-network-traffic.aspx You can search on some of the terms in that article for more explanations. |
