I thought it used to be that some budget hardware fell back to the speed of hte slowest attached device. Am I misremembering or has that limitation been removed from even the cheapest networking gear today?

You could have a point. My LAN knowledge is more theoretical (kernel side) than practical so if some cheap products mess up the protocol then it might happen.

*nod*
however, now that I'm more awake I think the problem might've been limited to hubs which AFAIK had to send an identical data stream to every attached port.

I think it has. Most of it anyway. Most switches and NICs these days transmit at the maximum rate supported along all points of the signal path. This means that if you had two 1G NICs connected they would use 1G. If they went through a 100M switch then they would use 100M.

Hi,
I'm using Windows 7 Ultimate (64 bit).
I have a new USB hub that is causing some problems.
If the PC boots up with the hub attached then the hub isn't recognized and some of the built in ports don't work (these ports have an external hard drive and a wireless network adapter plugged in). Some of the built in ports do work (these ports have the mouse and keyboard plugged in).
If the PC boots up without the hub attached then all of the built in ports work fine. If I then plug in the hub all the devices plugged into it work fine.
Any ideas what I can do to make the PC boot up and have all built in ports and all ports on the hub work correctly?
Thanks,
dlarkin77

Out of interest what are the error codes in device manager fo rthe failing hubs?
Do you know if the hub causes the same behaviour on XP?
Can you identify the driver associated with the hub? If so you could force it to start later, set its start type to 3 in the services\<driver name=""> key.
If you dont need USB boot capabilities then you could try moving it down the list in the BIOS, this might help.
Generlaly though this kind of thing is fairly typical of USB on post XP oses. Microsoft really messed around with the USB subsys on Vista, it caused a hell of a lot of problems which got carried over into 7. Previously working HW would fail, behave erratically, all sorts of stuff.

Your suggestion led me to this [^] hotfix that seems to have sorted my problem.
Thanks for the help.

My work notebook is horribly slow. I know this question has been aksed millions of times before, so I expect some answers to refer to standard guides or previous answers, but please help me preserve my sanity. I could use my home notebook, but I don't want to put it at risk travelling every day opn the scooter.
The machine is an Acer Travelmate 5730, Core2 Duo 2GHz with only 2GB ram.1 I am running Windows 7 Enterprise, Office 2007 Ultimate, and Visual Studio 2010 Ultimate, with ReSharper. Before removing essential tools like ReSharper, I'd like to cut out unncessary services, indexing, etc. Unwanted background processes and all that. I've run VS 2010 withj ReSharper before on 2GB and it's been streets ahead in terms of speed.
So, where do I start?
1 I will buy ram and lend it to the company when I have money.

maybe that works good enough on a 32-bit Windows, however I wouldn't do it, all those fancy "Ultimate" and "Enterprise" words don't compensate for a lack of memory.
Isn't your Win7 a 64-bit edition? if so, I definitely would not go for only 2GB. Make it 4GB at once, then clean up your environment if necessary.

Thanks Luc, but you have told me nothing I didn't already say I knew in my question. It is work issue machine, and all are standard 2GB. When I have cash, I will put my own 4GB in the machine, on loan to the company, until I prove myself and they give me a new HP, like the more senior guys have. 
I'm looking for guidelines on which resource hogs to remove and which ones to detune.

really? one of us must have missed a few things then.
IMO if it is Win-64 (I'm still waiting on that info) then whatever you do with only 2GB is a waste of time. And if they want to save less than 100$ (that[^] is what 4GB cost) and don't care you're working well below your potential, then you're in the wrong company.

Oh, I'm working in the right company alright, for many reasons. I'm sure if I motivate enough I'll get the 4GB, but I must first at least finish my first project on time (it's already over the 1st deadline) before I make any demands.
BTW, I'm running Win 32 bit.

Good. You'll have to put it on a diet now.
1.
Avoid all fancy stuff; e.g. turn off Aero and all kinds of animation.
2.
Use TaskManager and sysinternals/autoruns to identify each and every redundant process, and how it got started. Remove/disable everything you don't need. There will be dozens of "utilities" that periodically check for updates, (claim to) provide assistance at some tasks, etc. Chuck them all out. When in doubt, type the process name in Google's search box. Using a second PC for this is handy!
3.
Some people claim registry fragmentation is high on the list of suspects; and there are tools to deal with that. I have never used any though.
4.
Now take care of your disk. Remove unnecessary files, limit the size of the Recycle Bin, remove all your browser history and cache, and limit the size of your browser's cache, etc. Then defragment.

Have you checked in the task manager whether you use more or less than the 2 GB of memory you have?
If memory is the bottleneck, most other solutions will have only a comparably small impact.
Otherwise the solutions are mostly common sense.
0. Uninstall programs you don't use.
1. Make sure your HD is not having more than 80% of its space used, and defrag it.
2. Get PageDefrag[^] from Sysinternals and defrag your Pagefile and registry hives. (Probably not necessary, but what the heck)
3. Get a reasonably fast USB stick with more than 256 MB and run readyboost on it. The less memory and slower HD, the bigger impact with this one.
Shutting down services have only a small impact on Windows seven as unnecessary services aren't started until you enable those roles.

Regarding services, this website has advice on what you could do http://www.blackviper.com/[^]. Clear the "rubbish" that builds up over time. Do that by using the MS Disk Cleanup utility as well as the Piriform CCleaner - note, some cleaning utilities are not particularly safe to use but CCleaner is fine. Defrag regularly but you might have better results using the Piriform Defraggler. Use SysInternal's AutoRuns to question what starts up at boot time and uncheck entries as necessary.

Don't do that. You'll be wasting your money and may not get the memory back when the notebook has to be turned in. Prove that it's your memory in there.

I'll replace my memory with their memory again if I turn the notebook in.

That only works if you don't end up having to turn the computer in at an unexpected time, eg when being terminated for tampering with a company asset (your laptop, caught when their big-brotherware spots a hardware change).

We're not such a large, big-brotherish company. I didn't even sign for the notebook, guy just handed me one and said, "Here's a notebook"

One very simple thing that I have seen work effectively a surprising number times is to give the thing a very thorough cleaning. I mean you should get a small can of compressed air (specifically for electronic devices) and blow out all of the vents you can see and open as many of the hatches as possible and do this there also.
The reason is that laptop CPUs throttle down their speed when they heat up. When they are very dirty with lots of dust inside that interferes with the ventilation and cooling of the machine so it gets hot and slows itself down. This happens a lot but it is such a slow process that people usually don't notice it until it gets really dirty and the machine is always slow.
Of course, everything else people have said is helpful too but if you have tried all of that and it's still slow then try this. You might be surprised.
