T410 performance issues..

My t410 laptop is pretty slow from last few days. Haven't installed anything specific except Orace db express edition.
Moment I start few programs, it takes lot of time to switch from one program to another..
Right now, following programs are running
Samtime Client
Microsoft outlook
3 ie windows with video playing in one of the windows.
few putty sessions..
It takes hell lot of time to switch from one of these programs to another.
Even spell-checker on outlook or browsing on ie takes easily 30 secs to respond..
Is it something to do with main memory size.. It is 2GB. Do i have to upgrade it..
It is baffling as my 5 years old dell laptop (pentium IV, 1Gb ram) runs better than this.
do we need thinkpad preloaded softwares like thinkvintage toolbox.

T410 Network Adapter Issue

I have a Lenovo Thinkpad T410 with WIndows 7 . It has "Intel 82577LM Gigabit " network adapter. The issue is that , sometimes, my laptop doesn't connect to the internet. The problem is very intermittent. There is no issue with my wired network connectivity , as I'm able to connect to my Sony Vaio Windows 7 laptop without any problem.
I have tried everything I could get on Internet forums. I updated the network driver also. But the issue still occurs sometimes, and after a few hours , inexplicably, it starts working fine.
Any help would be most appreciated.
Thanks,
Suraj

If you're talking about wired connection, try this:-
1. Click the "Start" button and choose "Control Panel" from the Start menu.
2. Click "Device Manager" on the "Control Panel."
3. Click the arrow icon next to "Network Adapters" to extend the category.
4. Right-click on your network card and choose "Properties" from the menu.
5. Navigate to the "Power Management" tab.
6. Remove the check in the box next to "Allow the computer to turn off this device to save power."
7. Click the "OK" button to confirm the new settings.
Let us know how it goes.

Write Data storage VI performance issue

I have a program that logs data from mulitple channels. It waits for 500 points from each channel, then saves the data (as a raw 2D DBL array) to file, wait for another 500 points, saves and so on. At the end, I have a raw file. I created a utility VI that would take the raw file and converts it to a tdm file so I can read it in Diadem. The utility VI has a for loop. In each iteration, the loop reads one data segment (the 500-point 2D array), converts the channel data to waveforms and then writes/appends to a tdm file using the Write Data (Channel) storage VI. The VI works fine for small files. But as the file gets larger, the conversion time seems to increase exponentially. Eventually grinding to a halt.
I noticed that each iteration of the for loop seems to take longer and longer. So I suspect the Write Data VI may not be simply appending to the existing channel data. But instead, each time it's probably reading back the waveform data already saved, recombine them with the new data and then rewrite the entire file. This is just a guess.
Anyway, I really need some help resolving the performance issue. Any response will be appreciated. The conversion VI is attached.

Here are two profile captures. Each capture start at the first entry into the inner-most for loop and stop when it exited the loop. Profile2.txt was captured when processing a RAW input file twice the size as in Profile.txt. I'm not familiar with the VIs listed, but it shows that lot of time was spent in _saveDdtAttributes.vi and _saveDDT.vi.

Qosmio X505-Q870 Performance Issues While on Battery

Hello to All,
I am new to the forum and wanted to present an issue to the knowledgeable regarding performance (gaming) while on battery. I've noticed that the Q870 performs very well in all facets of gaming, and there are very few games that this system cannot run. While connected to the wall outlet, the laptop consistently pumps out 45-75 fps in BFBC2 and the same framerate for other games such as COD: World at War and COD: Modern Warfare. The problem is the battery....
As soon as I unplug the laptop from AC power, the framerate drops to 15 fps and, in some cases with Crysis, 7 fps. I have the Power Options set to High Performance, but that doesn't seem to matter. I understand that the battery will be quickly depleted if games are run at full framerate, however, what's the purpose of a gaming laptop if the battery cannot handle the performance? I plan to augment the existing battery with a 20,000MaH external battery, however, I need to figure a solution to this problem or else the battery will be useless. Please help!!

Prime-time Performance Issues

I'm paying for Quantum Internet service 75/35, but lately I'm noticing that watching AppleTV and Netflix in the evenings is getting hard to do. It seems like between 9:30 and 10:30pm EST my FiOS performance is getting really bad. This causes shows to halt/buffer multiple times and is souring the entire viewing experience.
Here's my ususal (daytime) performance using Verizon's own speed test tool, which is what I expect:
And here's what I've been getting at night, about 3Mb/s or sometimes less:
As you would imagine, this is causing large buffering delays as I'm trying to stream HD content.
I know I can try to reduce image quality to minimize required bandwidth, but that's not the point; this is NOT the Internet service I'm paying for.
Please note that my AppleTV device is HARD WIRED to my FiOS router. Also note that I am not using the FiOS router's on-board WiFi; that's turned off and I am serving WiFI in my house via two HARD WIRED Apple devices (a time capsule and an AirPort Express). I am seeing this performance on all devices in my house at these times, whether they are wired or wireless. Also note that I'm getting this test from Verizon's own site, which is hitting their own servers, which means that the interface between Apple, Amazon, Netflix, etc. and Verizon shouldn't have any bearing on the issue.
Of course all calls to support have been about resetting my router, rebooting the ONT, etc. and nothing is getting better. I am trying to tell Verizon that they need to test the performance/capacity of their MAN/WAN infrastructure, but the agent can't do that, and can't even do a loopback speed test through my router to confirm or refute the performance I'm seeing.
I don't know what else to do at this point, so I'll put it to the community. It looks like a lot of other people are seeing issues aligning with evening (i.e. prime time download) hours and I'm wondering if Verizon has oversold their capacity in my area (Tampa FL). They may have the fibers that can deliver a gig to each house, but if they don't have the router bandwidth and the backhaul bandwith to actually support it out to their network edge, it's a moot point.
Is there any way I can get someone's attention in the network engineering team at Verizon? At this point they either know they have a major issue and don't want to admit it, or have a local failure (bad PON card, loose connector, overloaded internediate router, etc) that they have yet to diagnose. The call center staff doesn't seem to know how to get to the bottom of this.

Pavilion Dv7 4165dx Hard drive failure and performance issues?

I have a pavilion dv7 4165dx notebook that was working great until a couple of months when the performance of my machine started to decrease rapidly. I have performance issues with the machine because it takes 1 to 2 minutes to get from the welcome screen to the actual desktop and another 3 to 4 minutes for it to be ready to use. I already upgrade the memory from 4gb to 8gb but instead of going faster it goes slower and i also did a clean install of windows but it didn't help. Before i have problems it took maybe 30 to 50 seconds to go from the welcome screen to the actual desktop and 1 minute and 30 seconds to be ready to use and by the way i use soluto to tell me when the machine is ready for use.Then last week i notice that the headphone jack wasn't working properly so i contact hp and they told me to send them the laptop so i did, they replace the motherboard and they send it back to me and i just got it today it got a little better but it still lags on the welcome screen and to open programs. I check the memory using memtest 86 and the memory it's fine, but i check the hard drive with HDD Regenerator 2011 and it show i have one delayed sector. Then i check on hd tune pro and it show me some WARNING on section Calibration retry count( as you can see on the picture below) so my question is should i be worry and send it back to hp or what can i do to fix the problem i am having with this notebook?

I have the same laptop and have had issues with it since the day i brought it home. I have had it for a year now and am now replacing the hard drive for the 3rd time. My guess would be its your hard drive because most of the issues you seem to be having ar the same ones ive been dealing with for a while. I can say I'm very mad about the quality of this laptop and am in the process of battling with HP over this issue. If you have a chance go online and look at all the hard drive issues that this laptop has had and even look at the HP forums for this issue it will irritate you and make you wonder why this hasn't been fixed yet!

Performance issues - CVI 2010

Hi all,
I have code I've compiled on a development machine - XP Pro with SP3 - and I'm seeing some performance issues on a similarly configured test machine. 2GB Ram, Pentium 4 CPU 2.8GHz. I had our IT person clean off another machine for me to use exclusively for testing (the other machine is our Tester's PC) and he gave me one with an Intel Core2 4300 @ 1.80 GHz. My code on my test machine runs like a top with NO problems.
We have another PC running Win7 on an Intel Core i5-2400 @ 3.10 GHz, RAM = 4GB. The code should be screaming on this machine but we're seeing performance problems here, too, that I believe may be due to the OS - Win7 may be a real hog.
Can anyone make sense of this? Is the dual core that much better even though that CPU is rated lower in PassMark Bench Ratings (http://www.cpubenchmark.net/cpu_list.php). We're trying to work all this out so we can advise the customer on which machine he needs to run our software.
Thanks,
Judy

Hi Judy,
Looking at the spreadsheet it seems unlikely that memory or cpu requirements are the root cause of the issue because the second machine in the spreadsheet with poor "performance" has almost twice the CPU clock speed and twice the physical memory of the fourth machine that runs well.
It sounds like your application is a fairly complex application that involves both GUI components and instrument I/O so what needs to be done is determine what part of the application is causing the bottleneck. There are many different factors which if not considered properly when developing applications that can cause performance problems such as thread deadlocks, device driver problems with the instruments or other hardware, needing to adjust the sleep policy for GUI events, writing to TDMS files in CVI versions before 2010 SP1, having memory leaks in the application code, etc. There is also a KB called Improving Performance of LabWindows™/CVI Applications that describes some changes which may help improve performance.
The overall message is that it is not only CPU speed and quantity of RAM available that can cause performance problems. A way to check the amount of RAM used by an application and CPU Utilization is to use the Windows 7 Resource Monitor to watch the application. This can be done by running Task Manager (ctrl + shift + esc), selecting the Performance tab and pressing Resource Monitor. This will open the Resource Monitor window where you can check CPU usage, Memory, Disk and Network usage for the application while it is running.

Performance issues with GOOP

I would like to use GOOP in my next application development. Does anyone know if there is known performance issues I should be aware of?

That is a great question. I found a couple of other threads in the LabVIEW forum which address performance issues with GOOP:

Performance Issue

Dear Friends, I would like to know
Will there be a performance issue, If I use 2D Array instead of 1D array. Because I'm working in a time critical issue.
And I would like to know How to optimize the time, in case of LabView. Is there any guide lines, If so, can you provide some guideline/Link
Thank you,
Best Regards,

Datasocket calls from Fieldpoint - performance issues

I'm noticing that it takes A LONG TIME for the fieldpoint units to READ data from a Datasocket Server. My program is currently looping and reading 4 Datasocket Items from a server computer(in a for loop) but it takes around 3 seconds for this process to occur. Any suggestions as to how i can "speed" up these datasocket reads? Would using a different protocol (to read datasockets item) be quicker?
Regis

"the loop time dropped from 3 seconds
to under 1 sec (about 750ms)"
I wanted to mention that the 750ms was a pre-defined wait time i placed
in the loop. Without a wait time, I dropped the loop time
to about 80ms.
Also, can anyone please help me with this issue?

T410 VGA display issues

I am finding on our T410 systems we are getting in that the VGA output is so bad my customers are complaining. The display has colors washed out and are fuzzy. I even compared this to the previous models on the same display.
T60/T61 both looked good (analog but good)
T400 less crisp and less color
T410 color and line edge are bad.
Anyone else seeing this? We are using discrete graphic versions and it seems as if this is part was made poorly to force adoption of display port. For my company that is a ways off as we do not re-bury monitors with every new system. (Not to mention that Lenovo did not have a monitor with display port until recently)
Anyone else?

I have had fuzzy display with VGA and after numerous phone conversations with the customer support, I had my motherboard replaced last week. Guess what !!! The problem is not resolved. I still have the fuzzy display and it is really annoying.
Despite of having dock (which only supports VGA) I have to use DVI externally and I cannot use external display at work because they all have only VGA...
I always wanted Thinkpad until I bought this T410. And now I say, NEVER AGAIN...

T410 DVD UJ892 Issue, 'prepared for safe removal'

When I first received my T410 a couple of weeks ago, several programs which access the Mat**bleep**a DVD-RAM UJ892 drive did not recognize it. I updated the BIOS and the programs seemed to work, that is temporarily.
The machine works better, but still the DVD drive frequently becomes unrecognized completely, or the icon in Device Manager is marked with a yellow '!' (Windows cannot use this hardware device because it has been prepared for “safe removal”, but has not been removed from the computer (Code 47). To fix this problem, unplug this device from your computer and then plug it in again.) Rebooting the machine causes the device to be recognized again and removes the ‘safe removal’ status.
When the device is in ‘safe removal’ status, any attempt to manipulate it with Device Manager will cause Device Manager to hang. Removing and plugging the drive back in will not return the drive status to normal. The machine must be rebooted. Seemingly this also causes the machine to hang when it shut down making it necessary to force it to shut down.
If one manually marks the DVD drive for safe removal and then removes it, it remains in the list of devices that can be removed, but is grayed out. The drive still appears in Device Manager as prepared for safe removal. When the drive is plugged back in, it is not recognized. A scan for new hardware will not find it. Only when the machine is rebooted can the drive be used again.
Any help in finding a solution would be appreciated.
Solved!
Go to Solution.

Now its working. I download and install the battery firmware then on the battery power manager I select: power source optimized. Now the DVD RW is always on and ready to go.

Z820 - Performance Issue

Dears,
I have a Z820 16GB ( Xeon processor ) and a Dell Precision M4500 8GB ( i7 CPU @ 2.13 GHz ), in both , the operating system is Window 7 64-bit ,
Office 10 is installed in both
While working on Excel files, i have experienced very low performance of Z820 when compared to the Dell M4500
In M4500 , i could open 4 huge excel files ( 55MB each ) and work on them simultaneously with no any problem , no interruption and no ( Not responding message ) , while in the Z820 , i had to force closing the files in many occasions due to ( not responding message in some cases or because the screen turned into black and flashes.
I had done some test as following:
Opened the same excel file in both workstations, typed my excel formulas that spread into 14 columns and run them down to 500,000 rows, the M4500 finished in 22 seconds , while the Z820 at the first time stopped with the ( Not responding message ) but in the second test it could finish the same function in 8 minutes.
I can share with you the formulas taht i used in excel if that helps.
I am really surprised because the spics of Z820 is much more greater than the spics of M4500
Could you please advise me what to do and where to start to resolve this problem?

Performance issue of a standalone vi in Win7

Hi all,
I've created a project which is completely running in FPGA Target. After I created a standalone vi which resides under My Computer in project, I saw that loop rate become 100 ms. On the other hand, the loop rate was about 20 ms in RT side. All calculations and control mechanism work in FPGA Target so I thought that I may not need to use shared variables. I thought that I could send the input values that are needed by FPGA Target with using "Open FPGA VI Reference" only. Do you think that I can do this?
Another question is that is there any option in LabVIEW to increase performance? Like use 4 core of processor or 4 GB ram?
Best regards,

Hi GerdW,
First of all, thank you for your quick response.
Sorry, I couldn't explain it well. I've attached some screenshots of my work. (By the way I am a newbie. So I may know some ideas or structures not so well.)
* I've never tried to build application before. I've always studied in Real Time. I want to create an application (executable file) so that user can control the system independently from LabVIEW. When I was working in RT, I didn't have any problem with timing. I had timing problems after I started to work in PC. Is there anything that I miss or anything that I know wrong with this?
* As I said above, I always worked and created vi files in cRIO. I thought that there is no need to work in RT if FPGA Target does everything. So I created a vi under My computer and I used Open FPGA VI Reference. As you can see from the picture, IP number appeared on reference. Can I use this way, right?
* I have a lot of values as controls in FPGA. FPGA takes frequency, offset and amplitude for 4 different sine wave generation vi. There are manuel control inputs (setpoints, proportional gains, etc.). Anyway, there are about 60-65 variables which are needed to be sent to FPGA. (single precision, integer or FXP variables) After that there are few things to be done outside FPGA like counting cycles of sine wave, finding max values of variables (displacement, force, etc.). I wanted to these in FPGA but there is not enough space in Slices. (You can see from file in the attachment.) Do I need to use RT? Because if I have to use it, those variables should be shared variable, right?
If I'm not still clear, please let me know. I will try to share more information and file.
Thanks in advance,
Best regards,
