Here is an article I found. I hope this helps someone. If so please leave a comment to keep this info near the top of the list for a while - give everyone a chance to read it! ****** Increase your CPU Bandwith in XP ********* Windows XP helps itself to 20 per cent of your bandwidth, a useful tip at TweakXP reveals. But although this sounds like the sort of thing that could easily fuel paranoia (what's it doing with it?), it's more just a case of sloppy and wasteful configuration. Read on... The culprit is the QoS (quality of service) packet scheduler, which is intended to preserve some available bandwidth for important applications and in order to maintain network performance. It does this for the best of reasons; in a business environment you probably don't want to have the system brought to its knees because Dave in support is busy warezing Emannuelle in Tibet (Would you believe it? This one really exists. Really.). But this doesn't necessarily apply if you're using XP at home and/or you just want to get a big file as fast as possible. XP reserves that 20 per cent even if you've switched off QoS via the services program, but this default allocation can be adjusted or switched off by running gpedit.msc. You go to local computer policy, administrative templates, network branch, QoS Packet Scheduler, and then you can adjust the reservable bandwidth level upwards or downwards as you wish. Note that the details tab confirms that it does reserve that 20 per cent, even if you haven't configured QoS. Note that this tweak doesn't seem to apply to Home edition, as several of you have pointed out to us. Tweak 1. Make sure your logged on as actually "Administrator". do not log on with any account that just has administrator privileges. To log in as an administrator: -click on start->logoff->logoff -in the logon screen hold Ctrl+Alt+Del. -in the user field type 'Administrator' <-case sensitive. -in the password field type the password for the administrator (if you don't have one leave blank) -press ok 2. Start - run - type gpedit.msc 3. Expand the "Computer configuration" branch 4. Expand the "Administrative templates" branch 5. Expand the "Network" branch 6. Highlight the "QoS Packet Scheduler" in left window 7. In right window double click the "limit reservable bandwidth" setting 8. On setting tab check the "enabled" item 9. Where it says "Bandwidth limit %" change it to read 0-- Click apply, OK, exit gpedit.msc 10. Go to your Network connections (start->my computer->my network connection-> view network connections). Right click on your connection, choose properties then under the General or the Networking tab (where it lists your protocols) make sure QoS packet scheduler is enabled. 11. Reboot , now you are all done.
