Hd tach - cpu utilization

I just wanted to share my findings in case anyone else is having this problem.
I've been running WinXP Pro for months, but last night while trying to figure out my freezing/rebooting problem I figured I'd run a Hard Drive benchmark to see my CPU Utilization.
http://www.tcdlabs.com/hdtach.htm
Hd Tach 2.61
After running it I found that my CPU utilization was 54% !!!! That's crazy.
I have MSI KT333 Ultra....newest via 4in1 drivers.
I looked and it was running at DMA 5, bus mastering was enabled in the bios. At this point I was confused, I tried switching cables...reinstalling drivers...looking for tweaks....no go.
Finally I noticed on Via's page:
http://www.viaarena.com/?PageID=66
They have "IDE Miniport Driver".....figured what the heck....installed it, rebooted, and BAM! my CPU Utilization is down to 9%....much better.
Thanks for reading my rant. I encourage some of you to try out this benchmark and see what you get.
Adios!

I don't think Speedfan gives you CPU Utilization during peak HD usage. That is something different.

AHCI cpu utilization skyrockets

This issue is a bit new to me--have done RAID and IDE setups for decades, but thought I'd tinker with AHCI. Motherboard is MSI 970a-G46. Enabling and disabling AHCI with an established Win7x64 installation is not a problem for me.
Problem is that after enabling AHCI properly, cpu usage soars to 25%-30%+ with the Windows AHCI drivers, and jumps to as high as 40% with the latest AMD chipset drivers. OK--this is what HD Tach reports, anyway. IDE settings for the same drives measure 1-2% cpu utilization. According to HD Tach, too, the performance of AHCI & IDE is identical. Ergo: I see no advantage for my client system running in AHCI and will return to IDE.
Agree--disagree? Suggestions? Thanks.

This is an interesting post... With my new build I was set Raid0 / IDE. I had an unhappy line in device manager and changed to AHCI. Then it downloaded the driver.
I have not seen a jump in CPU usage. But I also have not been watching it like a hawk. Hmmm
I am going to watch my AMD System Monitor for results. In a post of mine..earlier.. I was told, and did some tests of AHCI vs: IDE. I ran IDE on my other PC (listed below, HTPC) and am now AHCI on my main 990FXA-GD80. The difference between the 2 ways tested on my 790FX actually did show an advantage IDE, using Bench32.
Not a huge advantage.. but a little over AHCI. I don't know if the difference is really worth much inspection.
I am looking forward to the results you get WaltC
Thanks, Panther57...;) My "results" are really more of an opinion, but ...
Right now I'm not really sure what hard drive benchmark I should be using or trusting!...;) HD Tach's last release in 2004 is now confirmed on the company's site as the last version of the bench it will make--as it is, I have to set the compatibility tab for WinXP just to run the darn thing in Win7x64! But...I installed the free version of HD Tune (and the 15-day trial for the "Pro" version of the program, too), and the results are very similar--except that HD Tune seems to be measuring my burst speeds incorrectly: HD Tach consistently puts them north of 200mb/s; HD Tune, well south of 200mb/s. (A strike against HD Tune--the free version does not measure cpu dependency--grrr-r-r-r. You have to pay for the "Pro" version to see that particular number, or install the Pro trial version which reveals those numbers for 15 days.)
OK, between the two benchmarks, and after several tests, cpu utilization seems high *both* in IDE and in AHCI modes. Like you, it has been quite awhile since I actually *looked* at cpu utilization of any kind for hard drives. I guess I wasn't prepared to see how cpu dependent things have become again. Certainly, we are nowhere near the point of decades ago when cpu utilization approached 100% and our programs would literally freeze while loading from the IDE disk, until the load was finished. The "good old days," right? NOT, hardly...;) I suppose, though, that with multicore cpus being the rule these days instead of the exception, cpu dependency is just not as big a deal as it was in the "old days" when we dealt with single-core cpus exclusively and searching an IDE drive could literally stop the whole show.
Again, when running these read tests to see the degree of cpu utilization, I found that while the tests were all uniform and basically just repeats of each other, done a couple of dozen times, the results for cpu utilization in each test were *all over the map*--from 0% to 40% cpu dependency! And the same was true whether I was testing in IDE mode or AHCI mode. That was kind of surprising--and yet, it still leaves open the question of how accurate and reliable the two HD benchmarks that I used actually are. Besides that, I did find a direct correlation between the size of the files being moved/copied and the degree of cpu dependency--the smaller the files copied and moved the higher the cpu involvement--the larger the files, the lower the cpu overhead in copying and moving, etc. Much as we'd expect.
So after all was said and done--it does seem to me that AHCI is actually more of a performer than IDE, albeit not by much. I think maybe it demands a tad less cpu dependency, too, which is another mark in its favor. In one group of tests I ran on a single drive (I also tested a pair of Windows-spanned hard drives in RAID 0 (software RAID) in AHCI and in IDE mode, just for the heck of it...;)), I found the *average* read speed of the AHCI drive some ~15mb/s faster than the same drive tested in IDE. That was with HD Tune tests. But as I've stated, how reliable or accurate are these benchmarks? Heh...;) Anybody's guess, I suppose.
My take in general on the subject (for anyone interested) is that going to AHCI won't hurt if a person decides to go that route, but it also won't help that much, either. You definitely can easily and very quickly move from an installed Win7 IDE installation to an AHCI installation, no problem (some sources swear it can't be done without a reformat and a reinstall--just not true! They just haven't discovered how easy and simple it is to move from IDE to AHCI and back again.) Current cpu dependencies whether in AHCI or in IDE surprise me they seem so high. However, the last time I paid close attention to such numbers was back when I ran a single-core cpu, and back then cpu dependency numbers for a hard drive meant quite a lot. Today's cpus have both the raw computational power and the number of cores to take that particular concern and put it on its ear, with a large grain of salt!...;)
I have three drives total at current:
Boot drive:
ST332062 OAS Sata, boot drive
then,
(2) ST350041 8AS Satas, spanned in software RAID 0, making two ~500GB RAID 0 partitions.
Total disk space ~1.32 terabytes, all drives including RAID 0 partitions running in AHCI mode. (Software RAID is just as happy with IDE, btw.)
My Friday "project" is complete...:] Hope I haven't confused anyone more than myself...;)

Poor Rendering CPU utilization

Hi,
I just got my brand-new PC including a Intel Core i7 920 and ASUS P6T Deluxe V2 Motherboard running on Windos 7 RC. I created a demo project and exported a sequence to 1920i m2v format. I was very disappointed that the CPU utilization during the rendering process was only 20-25%. Same with rendering for preview within premiere itself. Is there any way to improve this?
- Stefan

Could there be a mistake somewhere? I ran the Sandra benchmark on physical disks and got these results:
With 6.00 ms access time your access time would be the same as a 15K SCSI-3 disk.
All the SATA disks, including my Areca raid show access times around 13 to 16 ms.
BTW, Sandra gave my raid a drive index of 1479 MB/s. It shows that interpreting these results from different benchmarks it a difficult job. The results vary so much between programs. For instance:
SANDRA:      1479 MB/s, but indicates the size correctly as 10 TB
HD Tune Pro:   745 MB/s, but indicates the size INcorrectly as 2199 GB
HD Tach:         802 MB/s
all on the same raid array. The same applies to access times, with Sandra 13.2 ms, with HD Tune Pro 9.1 ms. All my single SATA disks show around 13.5 ms access time in HD Tune Pro. The drive index for single disks do not vary as much, both Sandra and HD Tune Pro show around 91 MB/s.
From what I have seen it looks like HD Tune Pro is the most representative benchmark for disk performance, more so than Sandra.

High CPU utilization with JDesktopPane.OUTLINE_DRAG_MODE

Hello there,
since I updated from Java SDK 1.4.0 to 1.4.1_01 I recognized a problem with MDI Java applications using a JDesktopPane with JInternalFrames. When the drag mode of the internal frames is set to OUTLINE_DRAG_MODE, which should have a better performance than the LIVE_DRAG_MODE the cpu utilization goes nearly up to 100% an the drag of the frame is quite slow.
Does anybody else experience this problem?
(The problem exists in the application I develop and also in the IDE Netbeans, I use for development)
I am not sure if this is the right place for my problem, so if there is a better one to post it to, please tell me.
Thanks
R�diger

Hi,
I've also noticed this. It happens on Windows 2000 with 1.4.1, but not with version 1.4.0. Have you found a solution yet?

Are there any specific tests, or logs prior to isolate this issue?

Hi,
A few points:
> Use one of the recommended OVA templates
> Check if the spike is random or occurs at a specific time. If it occurs at a specific time it could be coinciding with something like DRS backup, CDR load, busy hours etc.
> Minimum set of logs needed for one such high CPU spike instance are:
Detailed ccm traces from all nodes
RisDC Perfmon logs
Proglogs
Also, capture the output of the following:
utils diagnose test
utils core active list
show process load

Can we control user request w.r.t Memory and CPU utilization in Oracle 10g

Dear All,
We are having Production with Oracle 10.2.0.4 (5 Node RAC, 32Gb RAM each) running on RHEL5.2 with 12000 Users. We have some schema say FIN, HRMS, SALES, REPORT and many dedicated users for those schemas. We need to control the user request against these schema with respect to Memory (or CPU utilization)
Suppose users using FIN schema can use Maximum 40 % of Total Memory, HRMS schema can use Max 20%, SALES can use Max 20% and REPORT can use Max 20%.
Is it possible to create any Service in Server side to handle this type of scenareo or any existing service which can be customised to fullfil this?
Please suggest me.......
Thanks,
Tusar

JDBC 'applications' quite often don't use persistent connections, and often do not exit gracefully by calling 'exit' or 'disconnect'.
This means the session will continue to exist.
It also means, if you don't establish any form of connection pooling and/or dead connection detection, you can throw whatever amount of memory in the server, and you will continue to report
'Now problems is coming'. Apart from crippled English, the general lesson any DBA should know is how these 'applications' operate, and, contrary to some, you can never ever fight problems caused by applications,
by throwing memory and cpu at the problem.
When I read your text, I also assume the application is not using PrepareStatement calls and not using bindvariables, this is why your 'application' is burning the CPU.
Find those 'application developers', sue them, or better still : Beat them with a whip, and have them fix their 'crapplication'.

Increase in CPU Utilization after migration from APEX 3.1.2 to APEX 3.2

Has any noticed any increase in CPU Utilization after migrating from APEX 3.1.2 to APEX 3.2?
Thanks,
Mark

Hi Mark,
Take a look at some of the usage reports within APEX (sessions, page views etc) to get an overall feel for where the time is being consumed.
You'll also find it useful if you can run a statspack report (or AWR, ASH etc) during a busy period to be able to drill down into where that CPU is being spent.
There's no magic answers here unfortunately, you need to track it down to where the time is being spent before working back up to find out where best to tune it.

Which metadata table in the BODS repository has data about CPU utilization of every job that gets executed?

I have to create a performance dashboard where I need to make a graph showing CPU Utilization for individual workloads. If every job corresponds to a particular workload, is there any metadata table that would contain how much CPU Utilization corresponds to a given job?

If i am not wrong, AL_Statistics and ALVW_History will have details of memory utilization.

Increased CPU utilization on Sup1A after upgrade

Hello,
I recently upgraded a 6009 with Supervisor 1A from CatOS 7.6(5) to 8.4(4). Baseline total CPU utilization before the upgrade was about 12%, post upgrade it sits at about 30%.
We have several similar switches throughout our network that we intend to upgrade as well, so are treating this one box as a testbed. We will soon deploy IP telephones to every desk in our network, and want to determine if this higher baseline utilization will be problematic for us.
Considering voice, should we be concerned about this? Will any changes due to voice deployment such as many trunks, QoS, etc. cause a significant jump in CPU that might put our baseline even higher?
Will the higher baseline CPU utilization affect switch performance? I know most forwarding functions do not depend upon the CPU, and are switched via ASIC.
thanks for the help,
Brad

The IDLE_Tasks process on which you are seeing a slightly higher CPU is actually an enhancement that collects information more effectively on crashinfo files (files generated when there is a crash on the box). This enhancement went into 8.3(x) and 8.4(x)
In the past "IDLE_tasks" processing was not counted and therefore belong to the "kernel and IDLE" process (which as you can see in the show proc cpu) accounts the amount of cpu not being used.
If you are upgrading other 6500's with Sup1a's make sure they all have 128MB DRAM just like this one has.

JVM 1.4.x IE 6 CPU utilization 100% when issue window.print

I am using JVM 1.4.2_04, IE 6 and WinXP Pro.
When visiting internet application having applet initialized, and click the PRINT link (window.print()), suppose the print dialog box will be shown, however, the CPU utilization draw up to 100% and the dialog cannot be shown over 10 minutes.
I had tried with 1.4.1_x, the same result found.
If using 1.3.1_x on the same application, no problem found, can anyone help.

case solved, which is due to the bug_id 4942346

Swiping causes spikes in CPU utilization.

Using app to monitor CPU on iPhone 5 and iPad mini. Swiping causes spikes in CPU utilization from 5% to 65% for every swipe. Heavy swiping causes processor to run near 100%. Seems abnormal.
Reduce Motion turned on.
IOS 7.1
Anything to make this not run so high? Battery drain seems much faster with just general usage.

Hey Apple. This is likely a major issue with battery drain. Constant CPU spikes will cause the CPU to heat which increases battery drain. Swiping should not peg the CPU. I suspect it has to do with how The screen is rendered to the user.somebody needs to look into this from Apple. This is been an issue for at least the last few iOS versions.

CPU utilization problem with JSF

Hi,
I am using MyFaces 1.1.4 and tomahawk 1.1.3.
I am using EJB 2.0 and weblogic server 9.2
I have a problem with the performance of my application. The response time for 500 concurrent users is arnd 10sec. However, the CPU utilization normally hits *95-97%.*
I have disabled all the logging to reduce the file IO. Also, all the code has been optimised. Still the problem exists. Now, I cannot think of any way to overcome this. My project is getting delayed because of this.
Request you all to pls help.
Regards,
Milan.

What type of server or servers are you using. I am assuming which I hate to do is that your EJB's are for CRUD and you a connection pool. Have tried to optimize the DB connection pool's ?.

Xsun (high CPU utilization) on Solaris 10 Sparc

hi
i have sun blade 1500 and am running solaris 10 on it. the machine is a 2 CPU (750Mhz) 4GB Sparc with the lastest cluster patch.
The Xsun process is alway at 50% util and the windowmaker (wmaker) is at 27%.
The Xsun is alway using all available CPU and the machine is really slow.. any help on what patch will fix the Xsun process ? any operation on the machine increases the Xsun's CPU util.
thx
Sriram

Hi sridhar,
can i know which platform you are using....
if it is solaris,
can you paste the details of the prstat -L -p wlpid 1 1 ---> which gives the light wieght pid threads
and also (pstact wlspid) for lwpid to process id mapping
or you can follow these steps for finding which thread is causing the hight cpu utilization
1.find the highest usage lwpid in prstat output
2.find the lwpid in pstack output and get the matching thread number
3.convert the thread number to hexadecimal
4.find the hexadecimal thread number in the server thread dump (nid= xxx)
5.determine what thread was doing to cause the high cpu usage
you can find similar way if it is linux..
ps u -Lp wlspid and thread dump
Thank you,
Bob
