I have my desktop computer with Win7 HP 32 with 3Gb RAM set to sleep after 4 hours of inactivity. When I wake it up it always takes 90 seconds of heavy CPU usage before it is usable for all practical purposes. The usage always involves one of the svchost.exe. files. The amount of time doesn't vary, no change over the past 2 years.
I was just wondering if it's common. Does everyones windows 7 desktop system do this?
All of my Windows systems have done this, since XP. I never use sleep because a boot only takes 20 seconds.
Curious to see what others have experienced though
Me too. I haven't thought to time a boot. Funny considering how many people worry so much about that.
I haven't experienced that so far. Something has got to be wrong with svchost.exe. I've recently reinstalled my Windows, partially because of that process, there were a lot of them running simultaneously, covering my RAM down (affordably, but still it was annoying). Now it's fine.
I do not say that you should reinstall your OS but consider that as a last option :)
I have both my XP and 7 PCs set to sleep after about 45 minutes of inactivity and neither one takes more than about 5 seconds to reawaken.
It is not normal for the systems to take that long to reawaken and become usable. I'd say 15 seconds should be the max.
This sounds more like Hibernate times. If I use sleep (rarely) it will wake in the time it takes for the monitor to turn back on, 10-20 seconds.
Here's some steps to try, have a look at #12 Optimize Windows 7

Sleep saves your desktop to RAM and puts the computer in a low power mode so waking is very fast.
Hibernate saves your desktop to a file on the hard disk and turns the computer OFF, so you actually need to restart to start working again.
However you do need to think about the settings before deciding. If you are using a laptop on battery power then hibernate is the correct setting for you, and waiting for the computer to restart is better than running the battery down.
From MS:Sleep is a power-saving state that allows a computer to quickly resume full-power operation (typically within several seconds) when you want to start working again. Putting your computer into the sleep state is like pausing a DVD player—the computer immediately stops what it’s doing and is ready to start again when you want to resume working.
Hibernation is a power-saving state designed primarily for laptops. While sleep puts your work and settings in memory and draws a small amount of power, hibernation puts your open documents and programs on your hard disk, and then turns off your computer. Of all the power-saving states in Windows, hibernation uses the least amount of power. On a laptop, use hibernation when you know that you won't use your laptop for an extended period and won't have an opportunity to charge the battery during that time.
Hybrid sleep is designed primarily for desktop computers. Hybrid sleep is a combination of sleep and hibernate—it puts any open documents and programs in memory and on your hard disk, and then puts your computer into a low-power state so that you can quickly resume your work. That way, if a power failure occurs, Windows can restore your work from your hard disk. When hybrid sleep is turned on, putting your computer into sleep automatically puts your computer into hybrid sleep. Hybrid sleep is typically turned on by default on desktop computers.
Sleep should work fine with Win7. I set all my installs to sleep at 30 and Hibernate at an hour.
In the rarest cases, there are problems which are normally resolved by updating the Display driver.
If not, I next check the Diagnostics-Performance log for what's happening at sleep or wake time once it's logged: troubleshooting steps
Next try the clean boot by turning off all Startup items in msconfig or CCLeaner>Tools except AV and gadgets. Next in msconfig>Services choose "Hide all MS Services" to see what's running without your knowledge, uncheck it, then check back in both locations for programs which turn themselves back on to turn them off in their Preferences or Uninstall them. You now have a clean boot.
Finally use the tool which the Pro's use to trace these issues which will present a multi-dimensional chart of your Resume to see what's hanging. If needed the top expert on this and author of the trace Cluberti will consult on your trace results: Gathering a Startup, Shutdown, Sleep, Hibernate, or Reboot Trace

This is the service host that seems to be involved. In this picture it's at 49% usage, but it gets worse. It's always the only service showing usage during this time
Thanks for the replies. I'll get a chance to read it all more closely this evening and try some of your suggestions.
