Windows 10: How to interpret the Task Manager stats

I am trying to figure out where is the bottleneck in my system, namely disk I/O or CPU, for my video editng tasks.

I newly loaded Win 10 Pro on a SSD drive, but found no difference in the final encoding performance, whether I put all the Video files on the SSD or a SATA 3 HD.

So I ran the Task Manager, but was just as clueless, as the data does not make sense.

I look the CPU Performance, it was never fully utilised. I presume the BLUE graph is the speed of the CPU, it varies when I change the Power setting to Balanced, and fixed at 3.2Ghz when High Performance was set. But the GREEN graphs utilitisation ( I think ) was never more than 40%, I thought OK may be it is disk bound

But looking at the disk performance whether the files are on SATA 3 HD or SSD, they were never utilized to more than 10% or so.

So it seems that the system is not disk I/O or CPU bound, what can it be?

The system was newly booted, and no other Apps are running. In fact, the Task Manager is not showing anything else that is remotely significant in the background.

Can someone help to explain this, or am I missing some other parameters?

cheers

How Do I Interpret the Throughput Value on Task Manager Ethernet Graph

Hi Steve,

The 100 Kbps that is inline with the Throughput is a default settings for the network virtualization view of a user. It does not mean that your connection can only be limited on that speed. Your speed still depends from your network provider, as you've mentioned,
you have 1 Gbps internet speed. This view only shows you how your internet connection is being utilized and successful delivery of your provider to your computer. It will calculate and will automatically change from time to time depending on the usage of your
internet connection.

You can visit a streaming website and watch it for a moment while observing the Ethernet Throughput. You will notice that that graph and the Throughput will change as you are utilizing your internet connection.

Regards.

 

How Do I Interpret the Throughput Value on Task Manager Ethernet Graph

Task Manager on the Performance tab / Ethernet selected shows a Throughput value. This is at the top right corner of the box containing the moving graph. At idle I a Throughput of 100Kbps. My link speed is 1Gbps as shown by the LEDs on the NIC card. When
I right click the Ethernet graph and select Network Details the Link Speed is 1Gbps and Network Utilization of 0%.

So what is the meaning of the Throughput number at 100kbps? I can see small spikes on the graph about every 1 second. The Receive number in the lower corner shows 16kbps flashing about once a second. So clearly there is little network traffic. I assume Utilization
is 0% because very few bits are being received every 1 second and it appears nothing is being sent. So my question about the Throughput number. Is it simply the vertical scale of the Graph? If that is so then calling it Throughput is misleading.

What does the Throughput number represent and how is it calculated?

You do not say how the "bottleneck" manifests itself.

Pictures say much more than words, and allow for more detailed answers - can you provide screenshots or snips that indicate what you say?

In particular the Task Manager data that "does not make sense".

Of course when involved with Video editing, you won't be looking at the Task Manager, or even the Resource monitor with its more detailed graphs and component resource monitors. No doubt you could switch to your editing task, do something, then return to the resource graphs to see any increase in activity.

The event viewer logs may indicate any problem.

 

Thanks.

The problem is through the Task Manager, I do not see any bottleneck. To me, with only just a single problem running with some background tasks, the program must somehow hit either CPU or disk I/O bottleneck, but not through what I saw in the Task Manager. I shall get some screen shots.

But CPU usage was only about 40-50%, disk I/O still has plenty of bandwidth left, so why the system run faster until either one of those hits the limit? May be I don't understand enough about time-sliced multitasking system. I am used to real-time multitasking systems.

If there are not bottleneck showing up, why can't the program run faster.....that's my point. So there must be a hidden bottleneck or mis-tuning of the system somewhere.

Ffrree, I wonder if you would get a more informed response in a forum with focused interests in Video processing and editing, where hardware performance and tuning for this sort of task with specialist software must be a regularly discussed subject? Here on Tenforums, much of the discourse concerns tangible performance issues which interfere with even normal everyday PC use following systems installed or upgraded to Windows 10.

Feel free to supply some information regarding your suspicions and findings and someone here with interests that transect yours will surely offer some helpful suggestions.

 

It is very possible for a multi core CPU to be a bottleneck even when total CPU usage isn't high. Most applications have limits on the number of cores they can use efficiently. Creating an application that can efficiently use multiple cores is difficult and many do not do it well. If one or more individual cores has high usage this is likely the case. Video editing is very CPU intensive.
