Feature request: Monitor, manage IE - CPU usage

I was wondering if this is the right place to make a feature request. As it happens when surfing with IE, having many tabs open, pretty quickly CPU usage can reach 100% even on multi core system. Presumably some website manage to run out-of-control scripts
in the background.
The real problem is now that I cannot tell which tabs produces which CPU load. All that task manager shows is the IE process with the tabs and the overall CPU usage for the process.
Regarding monitoring it would help to identify the tabs (website) which cause the heavy load. This could be added to task manager.
Further, to manage the tabs it should be possible to either start each tab in its own process
or perhaps better, have the ability to put unused tabs in 'hibernation' causing all scripts to pause there.

Hi,
you can post 'feature' requests to the IETeam at
http://connect.microsoft.com/ie
Task Manager in current windows versions lists all IE Tab processes.... Sort the process list by cpu usage to identify hungry tabs.
Typically high cpu usage is caused by
Web browser addons, incorrect browser settings (use gpu instead of hardware rendering) and flash or poorly designed websites or missing updates to your windows or third-party software. You may like to try running your browser in noAddons mode to see if that
makes a difference in cpu usage.... and also ensuring that you have enabled Windows Updates and that your computer has the latest updates from MS, Adobe etc.
MS has no control over what addons a user has or installs on their machines.
Post consumer questions about IE or windows to
http://answers.microsoft.com (Help>Online Support menu). Include with your questions the full links to any websites that you are having issues with....
Always... the first step in troubleshooting web browser issues is to test in no addons mode.

Feature Request: File Management for Creative Cloud Mobile

I like the new Creative Cloud app but I am surprised that it is not possible to manage any files or folders. This weakens the usefulness of the app since it forces a user to use the creative cloud website for this. This should be part of the app and would improve the functionality of the app.

SQL Server 2012 - RESOURCE MONITOR / PREEMPTIVE_XE_CALLBACKEXECUTE high CPU usage

Hello,
We are currently in the process of migrating an existing clustered SQL Server 2008 R2 instance over to a clustered SQL Server 2012 instance as we phase out the Windows Server 2008 with SQL Server 2008 R2.
The setup is identical for the SQL Server 2012 instance as it is on the SQL Server 2008 R2 instance. (meaning the RAM and CPU are both the same or better on the SQL Server 2012 instance)
The process in which we are migrating is that we're moving a few databases over to the new SQL Server 2012 instance each night. What we've noticed is that the CPU usage is much higher on the SQL Server 2012 instance than on the previous
SQL Server 2008 R2 instance even though the there is only 1/2 of the databases migrated to the 2012 instance.
Running the following script:
;with cte ([totalCPU]) as (select sum(cpu) from master.dbo.sysprocesses)
select
tblSysprocess.spid
, tblSysprocess.cpu
, CONVERT(BIGINT,(tblSysprocess.cpu * CONVERT(BIGINT,100))) / CONVERT(BIGINT, cte.totalCPU) as [percentileCPU]
, tblSysprocess.physical_io
, tblSysprocess.memusage
, tblSysprocess.cmd
, tblSysProcess.lastwaittype
from master.dbo.sysprocesses tblSysprocess
cross apply cte
order by tblSysprocess.cpu desc
Produces the following results:
In a clustered environment, is this normal and if not, does anyone know what this means or how to reduce the CPU usage?
Thanks.

Hello,
The following query may help us identify extended events or audit configurations running on that SQL Server server that are producing that high CPU usage scenario.
SELECT
s.name
AS 'Sessions'
FROM
sys.server_event_sessions
AS s
WHERE
s.name
<> 'system_health'
and s.name
<> 'AlwaysOn_health';
Hope this helps.

Feature Request: Project Manager Trim Compatibility with all formats please!

It's 2013, Premiere Pro CC is out, and is more "Final Cut Pro" than ever (thanks Adobe), but there are still some basic things that need to be fixed. This is a DOOZY!...
With DSLR media being used pretty much everywhere, the inability to created trimmed projects using Project Manager for H.264 clips (and GoPro clips, and more!) is simply insane. Seriously?
Help me Adobe.... please...
thanks

Actually, Kevin works right across the San Francisco Bay from where I live. So yes, he is here in the USA.
You will occasionally get some answers around here from people with Indian names, but we are happy to have them on the forums.
The conversation about how to deal with the various codecs has been going on for some time, and the more people who request the feature, the more likely they will get it done. I don't like to say that the squeeky wheel gets the grease, but pretty much? It does!
I know they are thinking about it because of some of the comments I have seen and emails I have received. It appears to be fairly complicated, but personally, I think it is well worth the effort.
I would like to be able to ingest subclips from Prelude without transcoding (I don't use Prelude because it is useless to me without this feature). Once ingested, if I only use part of a clip, I want it trimmed in the Project Manager to just the footage I might need in the future if I have to make minor adjustments. And yes, that includes handles. So if handles solve part of the problem, that's fine.

How could i get the kernel and user cpu usage for each process

Hi all,
In order to monitor the system CPU usage, I would like write a script to gather the kernel and user CPU usage for each process, like the prstat or top does. As always missing the shortlived kernel usage, prstat or top cann't get the precise CPU usage. I checked with the dtrace syscall, proc and fbt provider, but don't get which one is useful.
Please provide your comments and suggestion.
Thanks in adv

As I've studied the "dtrace" for a while, and seems Sun gives a pretty high score on this new feature.....I do want to know whether there's some probe can work for it, like writing a "dtrace" version prstat.You can write a prstat without dtrace. Because that's just polling at specific intervals and reading some process structures from /proc. You could have dtrace fire a probe every 5 seconds and read the same thing, but it wouldn't really be using any features of dtrace. Trhying to write it "in dtrace" doesn't make much sense.
What you could do that would be harder via other methods is to fire a probe at process exit that displayed the process information including total CPU time. They could print exactly when processes exited. Doing that without dtrace would be very difficult.

Why the OC4J instance CPU Usage still 99% even all user already Logout ?

Hi All,
We are running OAS 10.1.3.3 with ADF BC Application.
At midnight when all user already logout, I notice that :
- on one instance, CPU keep on 99.9 %
- on the EM I see that there is there are 5 active sessions and 4 active request.
How can there are 4 active request while I am sure that I am the only one that login to the EM ?
I have tried to KILL -3 to create thread dump, but it doesn't work
How can I know, what are the those 4 active requests ?
What should I do to find out what consume the CPU ?
Thank you for your help,
xtanto

This is a very serious issue, particularly for AIR applications.

I also suspect that this is the root of at least some of the performance problems with Flash CS4 on Mac, as the stage core / swfPanel players are likely each using a sizable % of CPU even when idle.

Copying from USB NTFS device with Dolphin (KDE) causes 100% CPU usage

I am copying +/- 30 GB of Music files (flac) from my external USB HDD which is formatted as NTFS.
I have installed ntfs-3g and am experiencing near 100% CPU usage. What's wrong?
Additional info: I am using KDE and initiated the copying through dolphin. KDE's system monitor only shows CPU usage near 100%, but no processes in the process view could be responsable.
Thanks!

What mount options are used for that ntfs drive?
Edit: There are many similar threads but I couldn't find a solution other than trying out some kernel and cpufrequtils fun.

CPU usage around 45% but heavy lag on windows 8.1

Can anybody analize my WPT app result in *etl format ? I'm so frustrated to find out what is cousing my laptop so laggy . . . I'm using windows 8.1, core i5 2,53 GHz, 4GB Ram, ATi Mobility Radeon HD 5730 on my ASUS laptop.
In task task manager show CPU usage around 45% but when i count it only about 5%, mem usage below 70% and everything looks normal . . . but why my laptop so lag i even can't typing in word . . . it also happened when playing game. . .dont care how small
the game like mahjong, solitaire, it's also lag . . . please help me . . .
I'm sorry my english is bad hope you understand what i mean. . . here the link to my WPT result :

Please Explain "Max CPU Usage" To Me

If this is as simple as "RTFM n00b" then please give me the link to the proper documentation page, because after quite a bit of reading, I'm no nearer an answer.
Oracle Cloud Control shows me in the "Top Activity" page that my CPU usage significantly exceeds the "CPU Cores" line (this red line appears to be called "Maximum CPU Line" in other areas?). This CPU Cores line sits at 1.0. The activity monitor shows my CPU usage at the 2.2 mark (obviously exceeding the red line by a significant margin).
However, I go over to the "Hosts" page and look at the "CPU Utilization" graph and it never shows CPU usage above 13%.
The host has 4 virtual CPUs and the database is 11r2.
What is going on here? Again, if this is all discussed in a man file somewhere, please direct me.
Thanks!

Hi,
My thoughts would be that the OEM seems to think that you only have 1 physical core because it's showing the CPU Core line as 1. When, in fact, you say that you have 4 virutal cores?
On our PROD DB, we have 8 physical sockets but 32 cores available. The OEM shows the CPU Cores line as 8 and CPU always exceeds it.
Personally, I use the OEM performance graph as a way to quickly identify issues. Spikes in CPU, locks, excessive I/O, etc. Then I can drill down as necessary. I leave it on in the background and just keep an eye on it.
I monitor the CPU usage from the server. If you know that you are not CPU bound, there isn't a problem?

Why isn't CPU usage maxed

I notice when I burn a project on iDVD the activity monitor shows the cpu usage btw 140 and 160% when encoding the video and like 30% when encoding the audio. I'm guessing if it showed 200% it would be utilizing all available processor power. Note my macbook has 2GB ram. This bothers me because the other day I encoded a video file that was 800MB that was 100 minutes and it took a little bit more than 4hrs to encode that. I didn't have anything else running? What gives?

It also really depends on what software you are using for the encoding. I've played with several the last couple of days and found out some interesting stuff. I used Toast 7.1 to encode a DVD into DivX for playback on a hardware DivX player. A one hour episode took 2 hours to encode using Toast (on my new MacPro). One processor was pegged, and the other three were basically idling. Today I used HandBrake to do the same exact task. This time that one hour episode encoded in 15 minutes. Watching Activity Monitor showed all four processors running at about 40% mostly in (nice) mode. The nice mode is good so that you can continue to use the computer for other tasks while it is working.
Obviously, it has a lot to do on the software. Both were Universal binaries, so I can't blame Toast's speed on Rosetta or anything else...

Mem / cpu usage of a script

Hi,
is there a way to monitor the memory / cpu usage of a python script?
thanks
Matthew

It depends -- what do you mean by "monitor"? If the script is run once, try time (/usr/bin/time from package time, not the shell builtin), with -v option. For long running, daemon-like scripts I'd use something like monit with few thresholds.

How much CPU usage should I expect?

I have a two week old MBP and I find that my battery performance is dismal. I'm only getting 2 hours per charge, and this is after Apple replaced my battery two days ago!
I think it might be related to my CPU usage...
Looking at Activity Monitor, my "% User" CPU usage is routinely above 26%, with only Safari running (no videos).
Even with no programs open I run over 25%.
Is this normal? If not, what IS normal?
Any suggestions?
Thanks!!!

what does activity monitor show is running?
RAM takes up battery life.
have you gone into energy saver and set things accordingly for when you are running on battery power? this setting is put there to get the most life out of your battery.

Config Manager Agent - after Hardware Inventory High CPU Usage with WMIPRSVE and very fast empty Battery

Hi there,
since a few days there is on some machines (40-60) a high cpu usage on one core (quad core cpu machines) with the WMIPRSVE.EXE if the HARDWARE INVENTORY CYCLE started.
i try out some tests, read some forum articles and troubleshooting the WMI management but a real problem i doesn´t see.
in some articles i read that hardware inventory runs about minutes up to more hours but some machines runs longer, someone more as 1 day.
here an example of mine PC:
at 8:07 i started Hardware Inventory Cycle, in the InventoryAgent.log i can see that some Collection Namespace are captured.
after a few minutes there stopped and does nothing round about 5.9 hours or better, after 21436.097 Seconds.
For any hints i am grateful. :)

Looks like something in one or both of those wmi queries. it goes from 8:10:03 to 14:06:43 right around there. 6 hours to do that...

Is there a way to monitor CPU usage during the execution of a vi?

I am wondering if there is a way, using LabView, to monitor the CPU usage during the execution of a vi. I want to be able to programmatically adjust the program controls based on the CPU usage. This program is designed to run all day in the background.
Thanks!

There are at least two Windows tools you can use to see CPU usage
(depending on what version of Windows you have). The Task Manager
(ctrl-alt-del) has a panel that shows CPU usage. There is another
program that has more options as to what to watch. Under W2K, it is in
the Administrative Tools in the Control Panel and is called Performance.
Play around with adding various new "Counters".
Another option is to measure CPU usage programmatically. George Zou
has a tool that makes the appropriate dll call. Check out

How to monitor CPU usage and performance on a Hyper-V server with several VM's

I have a server that is running Windows 2008 64 bit Hyper-V, with 8 gigs of RAM and Intel Xeon X3440 @ 2.53 Ghz, which gives me 8 logical cores in the performance monitor on the host system.
I have set up three Virtual Machines, all running Windows 2008 32 bit.
Build server, running Team City
Staging server
SQL Server, running SQL Server 2005
I have some troubles with the setup in that the host monitor remains responsive at all times, even though the VM's are seemingly working at 100% cpu and are very sluggish and unresponsive. (I have asked a separate question about that.)
So the question here is: What is the best way to monitor how the physical CPU's are actually utilized? The reason I am asking is that I am being told that i cannot reliably use the task manager to monitor CPU usage in a VM.

First, you have to remember that in Hyper-V that the "host" is called a parent partition and it really just like a virtualized guest with special permissions and roles. Just like any other child/guest, when you open up Task Manager, you can not see the CPU
usage of the other children on the server.
Ben Armstrong has a good explanation of this here:http://blogs.msdn.com/virtual_pc_guy/archive/2008/02/28/hyper-v-virtual-machine-cpu-usage-and-task-manager.aspx
To summarize his post, you need to check three things to get an accurate picture of CPU utilization:
View the CPU usage on each guest - this is available through Hyper-V Manager or Performance Monitor.
CPU usage due to context switching - this is the perfmon counter called % Hypervisor Run Timeunder Hyper-V Hypervisor Virtual Processor
Child partition worker process - vmwp.exe running on the parent partition (1 per child). This handles Hyper-V operations like saving
state.
