Windows processing speed revisited...

I apologize for posting a question similar to one that I previously posted but I think I may have worded the previous one incorrectly. The response I received was informative and I appreciate it but I am still seeking an understanding of something.....Some programs that I run in Vista run so slowly that they show as 0% CPU in Task Manager, i.e., they are running at less than 1%. Meanwhile, I can have no other jobs running and my new PC is at 98-99% idle. That just doesn't make sense to me. I appreciate the response I got in the previous message that explained that some software is not programmed to run best with a quad processor like I have. That makes sense. But even if they are using only one of the processors, why would they utilize so little CPU? It was also explained that I should see a big difference when I am running multiple programs but if programs are running so slowly when no other applications are running, they are going to run slow when other apps are running. As an example, I started a Windows Defender Scan and a Avast! virus scan at about 3:00 this afternoon. It is now past 10:00P.M and they are still creeping along at less than 1% CPU usage while my system is idling. Changing their priority in Task Manager has no effect. In fact, I set them at high priority. They are so slow that I had to turn off my sleep mode setting and I will have to let my PC run all night and maybe well into tomorrow to finish the scans without interruption. It's hard for me to imagine that this is right. I could understand this if they were using all of the CPU for one processor but they are hardly using any CPU at all. Any suggestions would be appreciated.

You should have just clarified your other post rather than start a new one.Download 
and run Orthos stress test and see if your quad gets all 4 cores 100% usage.You will 
have to copy it so you have 2 folders with orthos in it and run 2 instances to use 
all 4 cores as it only uses 2 per instance.I know it says for XP but it works in 
Vista.

I guess there's a general answer for this. If your cpu is only at say 1%, it may well mean that cpu speed isn't your bottleneck. There are lots of things that can be a bottleneck for speed besides cpu. Your applications might be waiting for some task which is not cpu intensive to complete.

As an example, disk access/io speed, networking speeds, whether it's loading a huge amount of memory (it only allocates memory so fast you know, if you're loading gigabytes into memory or something it's going to sit there a while), whether you're caching memory to disk because you don't have enough ram, or stuff like that. All of these sorts of things can slow you down.

There are various solutions depending what is wrong, some of which have hardware solutions. If you are doing a lot of disk io, you can buy hard drives with faster rpm speeds. If you're caching memory to disk, you can put in more ram. If you don't have enough temporary space on your drive you can delete some files and make room.

As a starting point, I'd suggest loading task manager, adding extra columns to display more stats like io etc, and just watching your applications to see what kind of numbers are moving. The goal is to find out what is pinned or heavily used, disk io, memory loading, cpu, whatever.
