How to measure slow disk i/o impact on video graphics performance???

The problem is when an application runs in fullscreen with a high FPS and still shows lag/stutter issues in graphics ...
Windows 7 doesn`t seem to have any tools that report of stuck disk i/o traffic and neither does the graphic card controls (nvidia). The missing information seem to be:
1) Whether it is because of a slow drive (fx. http://www.youtube.com/watch?v=QF-SBypQBuw); (Solution: buy a faster drive)
2) Whether it is because of other programs using the same disk - fx. windows pagefile(?); (Solution: move the app to another drive)
3) Or whether it is because of a layer program - fx like Sandboxie that redirects filesearch etc.; (Solution: run the app outside the layer)
Is it really necessary to buy and install and configure a new harddrive and then install the app on this drive uncertain of results just to compare to try solving some graphics lag because of disk i/o issues?

1) the Windows performance index gives a view of the hardware's expected performance the subscores for harddrive tests should allow you to determine if your harddisk is 'slow'
2) Resource monitor can help to identify processes that have a lot of IO. Most important measurement will be teh disk queue length. To get even more detailed information, you could use perfmon.
http://blogs.technet.com/b/askcore/archive/2012/02/07/measuring-disk-latency-with-windows-performance-monitor-perfmon.aspx
3) virtualisation and/or sandboxing always has a performance impact. You should check with the software vendor how to check for/test the performance impact the application has.
no, it is not neccasary to buy hardware or software to identify a performance issue. note that in some cases is might be easier/cheaper to buy some new hardware of which you are sure it will meet all requirements.
PS: consider purchasing an SSD if yous suspect IO issues and are willing to spend some: it will be your best hardwareupgarde you did over the last 10 years!!!

How to actually build a great linux machine? Poor graphics performance

I can't believe I am asking this question myself. I've been using linux since 1996, SuSE version 4.1...And yet I am still not able to put together a well performing machine.
I bought a simple box a few months ago. I am a software developer. I don't need high end graphics nor RAID nor stuff like that. My main goal is to have a fast responsive machine. I installed arch linux on it, and i3 as desktop environment - really it should be quite fast.
And yet...the machine responsiveness is very low, especially graphics lag A LOT. I know I didn't opt for a high end graphics engine - but shouldn't such a modern machine be enough for lag-free youtube and other video watching? Lag-free firefox browsing?
Maybe I just misconfigured my machine, and that's what my question is about. Some hardware info follows below. As you can see, I have a AMD E-350 processor with 8GB-RAM - I should think this would be quite enough for a standard linux installation...
What I also did is, as the MoBo comes with a GPU/processor bundle, I thought that maybe upgrading just the graphics card may have some impact - nope. I bought a AMD HD5450 card with 1GB RAM (!!!) - and still I can't enjoy a fluent video on youtube, nor a sufficient experience web browsing...(maybe it's even better to have the original GPU than the added card I bought?). Of course I know that modern browsers are pretty demanding, but I should think such a machine should be able to handle it?
I read the posts on the arch linux forum about optimizing video, and AMD cards are not very well reviewed really...
There are infinite sites about how to choose your distro, there are hardware compatibility lists - but are there any tutorials or guides which actually help setting up a fast and responsive machine?
* Is my machine maybe badly configured?
* Does it just have a bad hardware set up? Should I maybe replace one or the other piece to cheaply get satisfactory performance?
* Am I just asking too much from my cheap hardware?
I am considering replacing the whole MoBo (I know it was cheap and I shouldn't expect too much from it, but I thought I should be able to tweak it...)

If I am not mistaken, the E-350 is equivalent to the Intel Atom D525. I have the D525 and use it in my media center. It performs very well at one task at a time, but dies a horrible death under multi tasking situations like a desktop. I blame browsers. I have a top-end laptop with the second fastest mobile i7 I could buy (in Dec 2014), a Geforce GTX 970m, that shares 6GiB VRAM with the intel 3D chip, and on top of all that 32GiB quality RAM with reasonable latencies. I'd really like to brag, because the thing was insanely expensive, but there are no grounds for bragging. When I open a browser, I still feel like it's 2004, everything is sluggish and slow and websites become more full of crap every day, everything is big and blaoted. The desktop, no matter which one, does not feel the least bit snappier than it used to ten years ago, although the processing power has multiplied. Desktops now have more crappy features, more "connectivity", more need to do everything. The immense availability of fast hardware and fast networks in metropolis of metropolis centered countries creates the illusion of an abundance of everything. And now I'm sitting here and all I want is a low power low cost machine to do every day tasks. While the industry is going on and on about the internet of things, I still wait for the day the internet of people happens.
It's not you. It's like interface designers are trying to mock us. Instead of snappy technology on snappy hardware with snappy code and a snappy workflow, we get "our interface is based on common technologies like HTML and CSS" in the ads for a static local operating system. Nothing ever works. We just had arrived at the following points in tech development:
- Gnome probably had every possible feature on the planet, that made a desktop useful, there were plugins for everything, a setting, a switch.
- Web sites on big screens finally became versatile, feature rich and less static.
- Desktops generally performed very well. Click-Action without a delay.
Then the following happened:
- Gnome 3, new desktop concept, rewrite, all the plugins are gone, I have to re-learn everything from the scratch and, since it was new, I have to re-arrange my workflow.
- Now we are supposed to look at the internet through a <5" screen. If feels like 2001 again, browsers suck, where are my addons, my plugins, my customization?
- Desktops use simple languages, that swallow performance like a maniac.
Of course you cannot really buy classic stuff the way it was, because the consumer marked is trend based, not centered around ergonomics. Another five years from now on:
- Gnome 3 has all the good features and works well for everybody, because there are plugins, custom interfaces and whatnot. But it has to be replaced by Gnome 4, because it does not work well with tactile feedback and bowel movement based controls. Adapting the old system is not possible, let's do it again.
- Mobile browsers are finally comfortable, but we are not supposed to look at the internet at all anymore, information has been simplified to the point, where it is sufficient to put small plugs into our orifices to be informed about everything important by short bursts of vibration and temperature change.
- Desktops had a chance to catch up with the inefficiency of a "if it's not interpreted or byte code, then I don't want it" mentality, but now everything has to be in 3D, projected on thin air with a multi trillion cubic voxel resolution. And everything is slow again.

I ran Advance System Care 3 Disk Optimizer program and now my drop down menus are too fast. How do I slow them down

I ran Advanced System Care3 disk optimizer program on my computer and now the drop down menus in Firefox open too fast. Mostly in the Bookmarks menu with nested folders. I went into the registry and changed all the "MenuShowDelay" data values back to 400(which were changed to 200 by the program. All the other windows programs drop down menus went back to the original speeds and are fine. Firefox did not change back to it's original delay speed. Where is the registry entry or configuration file for Firefox? How can I slow the menu down?
Thanks,
Tony

I want to set up the Time Machine and I would love to use the Time Capsule but since I already have a wireless router I need suggestions on what other external disks Apple could recommend to use with the Time Machine and how to configure that disk

I want to set up the Time Machine and I would love to use the Time
Capsule but since I already have a wireless router I need suggestions on
what other
external disks Apple could recommend to use with the Time Machine and
how to configure that disk.
A complication that I need to resolve is the fact that I am using Vmware
Fusion to be able to use Windows on my Mac. Now it seems that Time
Machine is not backing up my files
on that virtual Windows without additional configuration and my question
is whether you can advise me here or whether this is only a matter for
the Fusion virtual machine.

If you want to use Time Capsule you can.. you simply bridge it and plug it into the existing router.. wireless can be either turned off or used to reinforce the existing wireless.. eg use 5ghz in the TC which is much faster than your 2.4ghz.
You can also use a NAS.. many brands available but the top brands are synology, qnap and netgear readynas series. These will all do Time Machine backups although how well always depends on Apple sticking to a standard. There are cheaper ones.. I bought a single disk zyxel which was rebadged and sold through my local supermarket. It actually works very well for TM at least on Snow Leopard. Major changes were made in Lion and again ML so do not instantly think it will work on later versions. I haven't tried it yet with those versions.
Any external drive can be plugged into the mac. Use the one with the fastest connection or cheapest price according to your budget. USB2 drives are cheap and plentiful. But no where near as fast as USB3 or FW800. So just pick whichever suits the ports on your Mac. Interesting Apple finally moved to USB3 on their latest computers.
TM should exclude the VM partition file.. it is useless backing it up from Mac OS side.. and will slow TM as it needs to backup that partition everyday for no purpose.. TM cannot see the files inside it to backup just the changes.
You need to backup windows from windows. Use MSbackup to external drive.. if you have pro or ultimate versions you can backup to network drive. But MSbackup is a dog.. at least until the latest version it cannot restore the partition without first loading windows. There are about a zillion backup software versions for windows.. look up reviews and buy one which works for you. I use a free one Macrium Reflect which does full disk backups and is easy to restore.. to do incremental backups though you have to pay for it.

How to measure mapping execution speed

Hi,
currently i'm trying to measure performance differences between Interface Mappings which contain one single Message Mapping and Interface Mappings which contain 2 or 3 Message Mappings.
I already tried to do this with RWB and Performance-Monitoring. But Performance Monitoring shows the processing time through the whole XI, and not only Mapping execution time. So it is difficult to get a clean measuring there, without influences from queueing and so on.
Test Tab on Integration Builder has a too big step (one second). Mapping execution time is slower.
Do you have any ideas to measure this?
Or do you have experience with performance differences between those two kinds of Interface Mappings?
regards,
ms
P.S. i'm using XI 3.0

Hi, Manuel:
For the two scenarios you want to compare performance, trigger them separately.
You take following steps to take measurement for those two scenarios:
Go to SXMB_MONI, find the message, go to pipeline step after your "Request Message Mapping"
e.g. you can select "Technical Routing" step, expand it, -> SOAP Header -> Performance Header:
You will see the start time stamp for each steps executed up to current step.
Locate your mapping programs, get the begin time stamp and end time stamp, then you will know the how long the mapping program take.
For the scenario that you have several mapping programs, make sure you get begin timestamp for the first mapping program and end timestamp for last mapping program, the difference is the time for you few mapping program take.
Hope this helps.

I am using Oracle 9i... You might want to start with a feature of SQL*Plus: The AUTOTRACE (TRACEONLY) option which executes your statement, fetches all records (if there is something to fetch) and shows you some basic statistics information, which include the number of logical I/Os performed, number of sorts etc.
This gives you an indication of the effectiveness of your statement, so that can check how many logical I/Os (and physical reads) had to be performed.
Note however that there are more things to consider, as you've already mentioned: The CPU bit is not included in these statistics, and the work performed by SQL workareas (e.g. by hash joins) is also credited only very limited (number of sorts), but e.g. it doesn't cover any writes to temporary segments due to sort or hash operations spilling to disk etc.
You can use the following approach to get a deeper understanding of the operations performed by each row source:
alter session set statistics_level=all;
alter session set timed_statistics = true;
select /* findme */ ... <your query here>
SELECT
         SUBSTR(LPAD(' ',DEPTH - 1)||OPERATION||' '||OBJECT_NAME,1,40) OPERATION,
         OBJECT_NAME,
         CARDINALITY,
         LAST_OUTPUT_ROWS,
         LAST_CR_BUFFER_GETS,
         LAST_DISK_READS,
         LAST_DISK_WRITES,
FROM     V$SQL_PLAN_STATISTICS_ALL P,
         (SELECT *
          FROM   (SELECT   *
                  FROM     V$SQL
                  WHERE    SQL_TEXT LIKE '%findme%'
                           AND SQL_TEXT NOT LIKE '%V$SQL%'
                           AND PARSING_USER_ID = SYS_CONTEXT('USERENV','CURRENT_USERID')
                  ORDER BY LAST_LOAD_TIME DESC)
          WHERE ROWNUM < 2) S
WHERE    S.HASH_VALUE = P.HASH_VALUE
         AND S.CHILD_NUMBER = P.CHILD_NUMBER
ORDER BY ID
/Check the V$SQL_PLAN_STATISTICS_ALL view for more statistics available. In 10g there is a convenient function DBMS_XPLAN.DISPLAY_CURSOR which can show this information with a single call, but in 9i you need to do it yourself.
Note that "statistics_level=all" adds a significant overhead to the processing, so use with care and only when required:

How to measure RPM using digital I/O

Please tell me how to measure RPM using Digital Input or please give me a code for this.

You probably aren't going to find anyone to just give you code. Especially because you don't specify the hardware you're using. Doing this on FPGA is different than using DAQmx to do it. With FPGA you count pulses over a specified time. Using boolean logic from the digital DI node is a common way but there are others. (if you are using FPGA I can draw up an example, but I believe there is one on NIs website if you search google for it),. Then, if you want, you can run the data through an IIR filter, especially if you have a low resolution or slow moving encoder. Either of these conditions can result in very large difference of RPM even if the actual speed is not varying much (if you need an example why I can provide more detail, but some simple math calculating RPM should explain this. Obviously lower resolution will giv eyou less accurate results).
If you use DAQmx you can set up a frequency task and it will return the number of pulses in a specified time frame; then you can convert this to RPM based on your encoder resolution and take the same steps of running it through a filter to smooth it out if need be.

Slow Disk error when using Finale Cut

I get a slow disk error when trying to play something in finale cut but when i try to verify disk and repair disk i get Error: Could not unmount disk. What is going on and how do i fix it?

You have to boot from a DVD or external OS to fix the Disk. You can't unmount a disk that is currently hosting your operating system.

Dropped frames caused from slow disks (Disk Speed)

I just bought a hard drive enclosure that holds double hard drives. http://www.ewiz.com/photogallary.php?name=CA-400MXS2&show=g Inside the enclosure I put two 400G Seagate SATA drives and made them both scratch drives for my FCE 4 projects. Now when I'm inside Final Cut and doing motion tricks for my footage a warning keeps popping up saying "RT EXTREME HAS DETERMINED THESE DROPPED FRAMES WERE CAUSED BY SLOW DISK. PLEASE TRY:
-INCREASE THE SPEED OF YOUR DISK
-DECREASE THE NUMBER OF RT LAYERS
-LIMITING YOUR RT BANDWIDTH IN USER PREFERENCES
I don't know how to do any of those things above. Now I checked the user preferences and I couldn't find the "RT bandwidth" option to change. How do you change the disk speed or decrease the RT layers??
Sorry if this is common knowledge. I'm still new with this software.

Sounds like what I just went through,

just remember that if you raid, the drives should be as close to identical as possible.
i believe this is correct:
usb 2 = 480 mbps
fw 400 = 400 mbps
fw 800 = 800 mbps
that just means usb 2 & fw 4 are about the same, but fw 8 is faster / better for video.
Yeah I was looking at that one right after I posted. That's my #1 pick so far. You have an imac?

How to manage slow and fast moving goods in Demand Planning

Hi All,
Kindly let me know how to manage slow and fast moving goods in Demand Planning.
1. First how to detect slow and fast moving goods
2. which DP model to use
3. Any Best practice while dealing with slow and fast moving goods
Thanks
Arun

Arun,
There are two main concerns with forecasting slow moving goods. For fast moving, yes, trend, level and seasonality combined with a decent demand level gets you through.
So, either you don't have demand in the market for that product; if the product is not critical (like go/no go spare parts) I recommend just averaging out the demand over a period and going with that. Any errors incurred there won't have a significant business impact. On the other hand if it is critical, safety stock and/or contractual obligations come to play.
OR, if there is market demand but your market share is too low for whatever reason, then it gets tricky because you need a predictor variable(s) for which you have good knowledge off (such as CPI index, demand for related products, etc). The forecast is then done on the predictor variable(s) and the low market share applied to 'translate' the expected demand to the product in question. Unfortunately, the case of low demand/low market share I have no idea of how to implement it on SAP. Since forecasting is just the tip of the iceberg, it may pay to do it outside of SAP (say in Excel) and manually input it (unless the products are many and varied).
Hope this helps. Please let me know if this makes sense and/or applies to your question.

Dropped frames during playback due to "slow disk"

I work off an external Rocstor 160gb firewire drive; suddenly as I started to edit a project I get constant dropped frames during playback. It says it's due to "slow disks" and I wondered if my hard drive was dying. But I opened other projects on the drive and they play just fine. Why just this one? It's shot on the same format, captured the same -- nothing's different from my older projects. Maybe the captured media files got corrupted? I've never seen this. I've tried using the Rocstor on three different machines (first a 17" PB, then two different G5 towers) and it happens on all of them. I have FC5 on the PB, but FC6 on the G5s -- doesn't matter. I'm stumped here.

How full's the drive? The fuller it gets, the slower it becomes. If it wasn't a superfast FW drive to begin with (especially a 400 device) You're gonna have problems as it gets fuller... starts slowing down big time around 70% capacity. It's always something... if the drive's not in a fast enclosure, and is also a fastish drive has a least 8mb disk cache, it will behave like this with DV footage.
One thing I've seen and learned from reading a few posts on this is that the better/faster stuff suited for FCP use is worth the investment. G-Raid, Grainite Digital, OWC all sell really nice FW800 setups... they are up to twice as fast as older/slower FW 400 drives. and NEVER buy any more than you need now for storage. It's half the price and twice the speed next time you need more it seems.
eSATA should be considered by any pro. laptop or not.

How do I access Disk Utility for 10.7.1?

How do I access Disk Utility for 10.7.1? I found it in the forums a few weeks ago, used it, then lost the directions. This is a last ditch attempt
to use OS Lion. I parted my hair incorrectly when I installed and have been plagued by the dread rainbow spinning ball in EVERY application. Yes, every. Name one, Safari, Firefox, Text Edit, Mail, Excel, Word, iTunes, Garage Band, Calculator, Calender, iPhoto....yes, every, and I cannot
find a solution that works. I have back up files on two different hard drives 500 gig and 1 terrabyte with all my music, photo and writing files.
I am a writer and a musician so imagine the frustration. OS 10.6 is an option of course. My dedication to Apple and each new OS is deep so
I am hoping that somehow there will a fix, an upgrade, something that does not require me to go bac to the much more endangered species named OS.
hahhaa! Just stalled waiting for the ball to finish with it's random spinning.... SO, this is like a last desperate .... it just did two more stalls.
NO OTHER apps running, just little Firefox holding on for dear life, last desperate request for a fix.
MacKeeper has been great in sending helpful directions for getting the Antivirus to work after it mysteriously decided to stop working, Quite MacKeeper, go to Activity Monitor, force quit helper, start up MacKeeper and run program. It works!
SO before my third stall stops me, please post directions to open disk utility in administration mode so that I can do any further repairs that have not worked by using it from the open system. Also keychain synching stopped working with Lion.
Thanks to any and all who can help.

Press and hold Command-R keys and reboot. You'll then start up in the Lion Recovery HD. You'll find Disk Utility there.
Command-R to the rescue.
Just hold down Command-R during startup and Lion Recovery springs into action. It lets you choose from common utilities: You can run Disk Utility to check or repair your hard drive, erase your hard drive and reinstall a fresh copy of Lion, or restore your Mac from a Time Machine backup. You can even use Safari to get help from Apple Support online. And if Lion Recovery encounters problems, it will automatically connect to Apple over the Internet.

How to measure the baseline of a noisy, pulsed signal

Hi
I am measuring the torque exerted by a large motor on a shaft using a load cell and lever arm. The shaft runs at approx 150 rpm. I have attached a drawing that shows the output I get. This is a test rig.
I have written some code that measures the maximum peak out of a group of approx 5 peaks and writes this to a shift register. This gives me an idea of the maximum torque "spike".
I also wish to measure the baseline torque (due to the bearings in the machine). Even when highly filtered (my noise filter is set to 49Hz) the signal exhibits this noise which is probably due to vibration in the system. The signal is zeroed when the motor is not running.
Does anyone have an ideas on how to measure the "baseline" torque? The large spike in torque prevents me from doing a running average. Can anyone think of a way of averaging just the noisy part of the signal to get an average value? I aim to to subtract the average baseline torque from the peak value to get an idea of the torque due to the event which causes
the spike.
Any help would be greatly appreciated.
Many thanks.

drawing of torque signal.gif ‏26 KB

Thanks for the reply. I understand what you are saying. However, I might have to modify my method for measuring the peaks if I choose to implement your idea. I have taken a screenshot of my "peak finder" code and attached it.
Bascially, the reset terminal is wired to a timer which outputs a pulse every few seconds. This resets the vi (a standard NI one I think) and sets the peak magnitude back to zero. This way, I am windowing the signal and measuring the maximum peak in every window. This is what I need to do.
So I could use a logical filter to feed data to the running average only if;
the amplitude of the signal is less than a certain threshold
and if the current value has similar low peaks either side of it
How would you construct the code to delay the evaluation so that the values in front and behind of the current data point can be analysed?
thanks again

How to configure local disk on OVM Server as storage space to create VMs

Hello,
We have installed OVM Server 3.1.1 on a machine that has 250 GB of Hard disk space [Single disk].
While installing used an option - Remove all partitions and create a new default partition layout.
Around 4GB has been used and remaining 246 GB is left as free space.
From OVM Manager - the server is discovered but didn't discovered the physical disk [i.e. remaining 246 GB raw disk space].
Can someone help me to understand how to use local disk as storage space for creating and running VM's.
Thanks
Srinivas

You can? You've used every conceivable BIOS out there? You must really be full of yourself. There is absolutely no BIOS that I know of that gives this basic function. BIOSs do not "hard partition" anything. A "BIOS" is not made for such things. Do you even know what "BIOS" stands for?
I wonder why there is some many wanting to do this and are having problems.... I mean if it is such a straight forward thing to do..... It must be down right "intuitive".
You maybe speaking of a RAID "BIOS" but you obviously think you're not. Some motherboards have integrated RAID abilities. Intel RST comes to mind... BUT this isn't a feature of a MOTHERBOARD BIOS.
I've got some $50,000 servers that will not break a single hard drive up into multiple logical drives..... Now, I haven't worked on a "Stinkpad" for many years. Don't want to. However, I have never seen one that would do what you're saying you're doing.
You maybe trying to help.... but you're leading people down a wrong path.
Its just as easy to run virtual box and use the virtual box templates for Oracle VM. In fact, its more practical if you want to run Oracle VM on a laptop for testing purposes than blowing everything away and attempting to setup different LUNS on a single hard drive.
For your review...
http://www.oracle.com/technetwork/articles/servers-storage-admin/configure-vm-templates-1656261.html
Although it's more reliable to use a separate location (such as an NFS share) for a storage repository, you can use a local disk of your Oracle VM Server instead, thus taking advantage of the local storage option. Beware, though: Oracle VM Server 3.0 doesn't allow you to utilize the unused space on the physical disk it's installed on. For local storage, you'll need at least one more physical disk. In other words, you'll need a total of two disks at minimum on your Oracle VM Server host if you want to use local storage. In practice, though, local storage is not a primary use case. The major downside to this approach is that local storage, by definition, cannot be shared between different servers.
