MBP 17" HD Screen - Low Response time

Hello,
I found that my mbp with 17" 1920x1200 screen have a very slow response time of its Screen. It is very obviously when viewing photo slide show, from dark color to bright color, even watching any motion video, look like a horizontal line will appear on anywhere of the screen. But it is totally problem when viewing on an external monitor with same resolution. Do any HDmbp owner have such problem ?
thanks.

Is there anyone has the same problem with me ? I want to figure out is that problem only happen on my mbp or everyone have. I will try to take it to repair if I am not the lucky one. But you know....repairing servies is nightmare in my country. Thanks.

IMac screen response time?

I plan to do some gaming on the iMac. What is the screen's response time?

would depend on the model really
IPS panel typically have a better looking image then TN panels
but at least on paper TN panels always have a lower response time

Response time: 12 ms
http://www.apple.com/displays/specs.html
to get the max worst case fps with 12ms you to a 1/12ms == 83.33Fps
but if the lcd panel has a refreshrate of 60Hz that will set the max fps unless you disable v-sync
in which case you're inviting tearing to happen which is bad mmkey
all those things being said I game on my imac 21" 2011 model mostly in windows8.1 and skyrim and batman A city and the likes and it runs great

12ms response time... is this rather slow for a high cost display?

I was waiting to buy the new 27" display but now that it has been arrived at a cost of £899 in the UK I am looking at cheaper alternatives, accepting that cheaper will probably mean lower spec. I am surprised to find that many much lower priced displays from manufacturers such as LG, HP, and Samsung appear to have faster response times, for instance 2ms or 5ms, whereas the Apple display's response time is listed as being 12ms. I think I am correct in thinking that a lower response time means that fast action video looks better on screen, but this doesn't seem to make sense that such an expensive and high quality display as Apple's would be slower, so am I misunderstanding something here?
What are the most important figures to take account of when looking at the spec of a good display?

You can look at other manufactures. Their price is usually lower. I have a HP 24" with a IPS LCD screen. Apple doesn't have an exclusive on IPS screens.

After IOS 8 update, the screen is jerky and the response time is really, really slow... Using a PC to submit this!

Is there a solution to a jerky screen and a slow response time after updating to IOS 8?

Try some basic troubleshooting:
(A) Try reset iPad
Hold down the Sleep/Wake button and the Home button at the same time for at least ten seconds, until the Apple logo appears
(B) Try reset all settings
Settings>General>Reset>Reset All Settings
(C) Setup as new (data will be lost)
Settings>General>Reset>Erase all content and settings

ERP screen response time

One of our clients is accessing his ERP system through a satellite WAN. Could somebody please let me know the ideal respose time for an ERP screen accessed by a satellite at a bandwidth of 512 kbps for one user?

I don't think it has specific value for the response time, but it is slow definitely.
SAP Note 161053 has topic on SAPGui performance in WAN
Probably you need to get performance trace to get the average speed.

Unresponsive or low responsive screen

Hello all,
I kept looking for an answer on this forums regarding a problem I'm currently facing but i couldn't find any,so here it is:
I bought my iphone 4 on 24th of September from Orange(the phone was produced on 35th week),everything is good except one thingy:when i lay my phone on the table and i try to operate it with only one finger it becomes unresponsive or low responsive but if i touch the phone's body(not press it) with my fingers from the other hand it works flawlessly,if it is charging I can operate it with one finger,if i put it on my leg i can also operate it with one finger the only problem comes when i put it on a table,book,etc and become unresponsive or very low responsive.
If an Apple representative could help me it would be great!
I can not reach an apple store as i'm not for US,i'm from Romania and Apple has only partners here.
Thank you in advance

Explain plan - lower cost but higher response time in 11g compared to 10g

Hello,
I have a strange scenario where 'm migrating a db from standalone Sun FS running 10g RDBMS to a 2-Node Sun/ASM 11g RAC env. The issue is with response time of queries -
In 11g Env:
SQL> select last_analyzed, num_rows from dba_tables where owner='MARKETHEALTH' and table_name='NCP_DETAIL_TAB';
LAST_ANALYZED NUM_ROWS
11-08-2012 18:21:12 3413956
Elapsed: 00:00:00.30
In 10g Env:
SQL> select last_analyzed, num_rows from dba_tables where owner='MARKETHEALTH' and table_name='NCP_DETAIL_TAB';
LAST_ANAL NUM_ROWS
07-NOV-12 3502160
Elapsed: 00:00:00.04If you look @ the response times, even a simple query on the dba_tables takes ~8 times. Any ideas what might be causing this? I have compared the XPlans and they are exactly the same, moreover, the cost is less in the 11g env compared to the 10g env, but still the response time is higher.
BTW - 'm running the queries directly on the server, so no network latency in play here.
Thanks in advance

"Windows 8 using 100% of HDD with high average response times and low read/write speed"

Turns out this is a fairly well known windows 8.1 issue that has been plaguing users since at least 2013 and there is no one simple fix, so it may not be *entirely* hp's fault; but I've had two of these laptops, both the same model, the first one needing to be returned and exchanged for an entirely unrelated issue (hardware failure: ethernet port nonfunctional with lights stuck on). Both are refurbished. Both have been extreemly slow and unresponsive even compared to a lesser Brazos powered laptop I had before, but I've only recently decided to investigate why.
So if there is something HP specific going on here, I hope there is one simple fix. My average response time has gone up as far as well over a minute (>60,000ms), so I may be an outlier case here compared to the typical windows 8.1 hardrive responsiveness/bandwidth problem.
Edit: there is a case with another HP pavilion laptop (intel powered though, so it may be an intel storage driver issue described in the first link) being much, much worse.
This question was solved.

Response time low to display 2700 records

In my program , i have tried to display 2700 records from Database using JSP.
But the response time is very slow. How do i overcome this problem.
My architecture is
JSP - EJB - HelperClass - DB.

Find out where the performance bottleneck is
1) Database -> use PreparedStatements,
reuse an open database connection
2) JSP -> Check your string handling, use StringBuffer() for appending
lots of strings together
3) Network response -> Maybe try defining a static IP address for your
server

High CPU response times, altough low CPU utilization

Hi Friends,
We have a performance problem after we migrate our basis system,
The current system is :
Database server : Sun SPARC Enterprise T5240 Server - 2 CPU's with 6 core, 8 thread, 1.2 Ghz
32 GB RAM
and we use another identical configured server as an application server.
Database is Oracle 10.2.0 and operating system is Solaris 10.
The problem is average CPU response time is 450 ms, and max. CPU load is %5 percent.
Pre-migration configuration with old servers, we had CPU response : 150 ms and max CPU load: 50%.
Has anyone of you, have experinced a similar problem with this new CPU's?
Thanks in advance

> I am aware that there might be lots of reasons, but what I guess is, there should be a parameter wrong with the CPU settings. This SPARC server CPU is a new tech. 6 core 8 thread one, which is expected to work much faster than the old simple dual core CPU.
Is it?
ABAP is basically a virtual machine and what is most important: ABAP runs single threaded. This means in consequence that the processing time of a program relies on the single processing power of one core. More cores means more parallelism but the speed of the single statement always relies on the power of one core and how fast it can get the data over the bus and back. So the significant number for speed is basically the Mhz (for ABAP, Java is very different).
Your old machine may have had a DualCore SPARC 1,2 Ghz and the new machine has one 1,4 Ghz 6core CPU (assuming so).
> However its response time is very high, although it is never utilized more than %5 percent.
see above.
> The problem might be at database settings(Oracle 10.2.0) or at Solaris ? ? ?
Well - no - I don't think so
Since ABAP is a single threaded application it can't leverage the CPU power due to the fact, that a parallelism in the program itself does not take place and hence the machine scales not linear with the number of cores. So you may have factually a machine with about 1 dot something CPUs and not 6 as you would expect.
This is not specific to SPARC CPU design but for all multi-core systems. A single threaded application is only as fast as the CPU speed. ABAP programs tend to be huge so you will also see effects of cache displacement and bus congestions. Less cores and more physical CPUs perform much better than any multicore CPU.
For Java the world is very different because Java works as one process (in the SAP case jlaunch) which has many many threads that can be executed in parallel on different pipelines on the CPU.
Unfortunately this is a design problem and there's not much you can do about it.

I m having a iPhone 5. since i upgraded the iOS to 7.0.4 i finding my Phones response time worse

my iPhone's response time is very slow, facetime doesnot work most of the time. once when i reset the iPhone to factory and tried to activate facetime it verifies the apple id but! it says "waiting for activation". What do i do? i waited fro two days and its still not working. Also my camera shutter doesn't open many a times. All started after ios7 upgradation... solution provider will be appreciated...

Howdy there Tuna241,
Thank you for using Apple Support Communities.
It sounds like your iPhone is restarting unexpectedly after the update to iOS 7.0.2.
I recommend the steps outlined in the article named:
iPhone: Hardware troubleshooting
http://support.apple.com/kb/TS2802
Will not turn on, will not turn on unless connected to power, or unexpected power off
Verify that the Sleep/Wake button functions. If it does not function, inspect it for signs of damage. If the button is damaged or is not functioning when pressed, seek service.
Check if a Liquid Contact Indicator (LCI) is activated or there are signs of corrosion. Learn about LCIsand corrosion.
Connect the iPhone to the iPhone's USB power adapter and let it charge for at least ten minutes.
After at least 30 minutes, if:
The home screen appears: The iPhone should be working. Update to the latest version of iOS if necessary. Continue charging it until it is completely charged and you see this battery icon in the upper-right corner of the screen . Then unplug the phone from power. If it immediately turns off, seek service.
The low-battery image appears, even after the phone has charged for at least 20 minutes: See "iPhone displays the low-battery image and is unresponsive" symptom in this article.
Something other than the Home screen or Low Battery image appears, continue with this article for further troubleshooting steps.
If the iPhone did not turn on, reset it while connected to the iPhone USB power adapter.
If the display turns on, go to step 4.
If the display remains black, go to next step.
Connect the iPhone to a computer and open iTunes. If iTunes recognizes the iPhone and indicates that it is in recovery mode, attempt to restore the iPhone. If the iPhone doesn't appear in iTunes or if you have difficulties in restoring the iPhone, see this article for further assistance.
If restoring the iPhone resolved the issue, go to step 4. If restoring the iPhone did not solve the issue, seek service.
Regards,
Sterling

I have a MacBook Pro, 10.10.2 Yosemite. My external hard drive no longer appears on my screen or in Time Machine

I have a MacBook Pro, 10.10.2 Yosemite. My external hard drive no longer appears on my screen or in Time Machine. I have gone into Disc Utility to repair disc, and get the message: Error: Partition map check failed because no slices were found. I was trying to follow Melophage's instructions by going into "Terminal" and entering "diskutil list; diskutil cs list; mount" and "diskutil info disk2." Then I entered the command "sudo got show disk1."   I am sure I have made the problem worse. Can you give me some help? Thank you. blelambert

racergirl,
have you tried resetting your MacBook Pro’s System Management Controller, to see if that makes a difference with the heat?

SAP GoLive : File System Response Times and Online Redologs design

Hello,
A SAP Going Live Verification session has just been performed on our SAP Production environnement.
SAP ECC6
Oracle 10.2.0.2
Solaris 10
As usual, we received database configuration instructions, but I'm a little bit skeptical about two of them :
1/
We have been told that our file system read response times "do not meet the standard requirements"
The following datafile has ben considered having a too high average read time per block.
File name -Blocks read - Avg. read time (ms) -Total read time per datafile (ms)
/oracle/PMA/sapdata5/sr3700_10/sr3700.data10 67534 23 1553282
I'm surprised that an average read time of 23ms is considered a high value. What are exactly those "standard requirements" ?
2/
We have been asked to increase the size of the online redo logs which are already quite large (54Mb).
Actually we have BW loading that generates "Chekpoint not comlete" message every night.
I've read in sap note 79341 that :
"The disadvantage of big redo log files is the lower checkpoint frequency and the longer time Oracle needs for an instance recovery."
Frankly, I have problems undertanding this sentence.
Frequent checkpoints means more redo log file switches, means more archive redo log files generated. right ?
But how is it that frequent chekpoints should decrease the time necessary for recovery ?
Thank you.
Any useful help would be appreciated.

Hello
>> I'm surprised that an average read time of 23ms is considered a high value. What are exactly those "standard requirements" ?
The recommended ("standard") values are published at the end of sapnote #322896.
23 ms seems really a little bit high to me - for example we have round about 4 to 6 ms on our productive system (with SAN storage).
>> Frequent checkpoints means more redo log file switches, means more archive redo log files generated. right?
Correct.
>> But how is it that frequent chekpoints should decrease the time necessary for recovery ?
A checkpoint is occured on every logswitch (of the online redologfiles). On a checkpoint event the following 3 things are happening in an oracle database:
Every dirty block in the buffer cache is written down to the datafiles
The latest SCN is written (updated) into the datafile header
The latest SCN is also written to the controlfiles
If your redologfiles are larger ... checkpoints are not happening so often and in this case the dirty buffers are not written down to the datafiles (in the case of no free space in the buffer cache is needed). So if your instance crashes you need to apply more redologs to the datafiles to be in a consistent state (roll forward). If you have smaller redologfiles more log switches are occured and so the SCNs in the data file headers (and the corresponding data) are closer to the newest SCN -> ergo the recovery is faster.
But this concept does not really fit the reality because of oracle implements some algorithm to reduce the workload for the DBWR in the case of a checkpoint.
There are also several parameters (depends on the oracle version) which control that a required recovery time is kept. (for example FAST_START_MTTR_TARGET)

Is there a way to keep Text2Speech locked in front on my screen at all times?

I want to be able to access Text2Speech at all times. It would be great to have it locked in the front of my screen at all times, even when I switch spaces. Does anyone know of a way to do this?

Hey Everyone,
DISCOVERED THE ANSWER!!!!!
I recently got one of these fun little squares and I just figured out (what seems to be) a simple way to keep the clock face on. (Though, I certainly agree with the comments about the ultimate impracticality of doing so for a long time, as the the battery in this thing only has so much to give.) I'm running the latest update on it.
This seemed too easy to believe when I did it! No need to keep it empty of music! No need to keep it in Fitness running! I think this works because the clock face, stop watch, and timer are all in the same segment of it's little nano operating system.
If you turn on the stopwatch then switch back to the clock face, it will stay fully illuminated as long as the stopwatch is running. I think the limit on the stopwatch is 24 hours, but my guess is your battery is going to be dead long before that. I'd recommend setting the brightness super low if you're going to do this.
Anyway, problem solved if you want to keep it lit for however long you like. (of course you have to sacrifice the stopwatch)
Enjoy!!
