IOS 8.1+ Performance Issue
Hello,
I encountered a serious performance bug in Adobe Air iOS application on devices running iOS 8.1 or later. Approximately in 1-2 minutes fps drops to 7 or lower without interacting with the app. This is very noticeable in the app. The app looks like frozen for about 0.5 seconds. The bug doesn't appear on every session.
Devices tested: iPad Mini iOS 8.1.1, iPhone 6 iOS 8.2. iPod Touch 4 iOS 6 is working correctly.
Air SDK versions: 15 and 17 tested.
I can track the bug using Adobe Scout. There is a noticeable spike on frame time 1.16. Framerate drops to 7.0. The App spends much time on function Runtime overhead. Sometimes the top activity is Running AS3 attached to frame or Waiting For Next Frame instead of Runtime overhead.
The bug can be reproduced on an empty application having a one bitmap on stage. Open the app and wait for two minutes and the bug should appear. If not, just close and relaunch the app.

Hi
Id already activated Messages and entered the 6 digit code I was presented with into my iPhone. I can receive txt messages from non iOS users on my iMac and can reply to those messages.
I just can't send a new message from scratch to a non iOS user :-s
Thanks

IPad 2 upgrade to iOS 8 causing performance issues?
I upgraded my iPad 2 to iOS 8 and it's now no longer functioning quickly enough to be usable. For example, it takes several seconds for the screen to simply shift from portrait to landscape. The delay in typing alone makes it unusable. Anyone else having the same problem? I tried to reinstall iOS 7 but wasn't successful. Anyone figure out how to fix this?
Adding more bellow.....
(Same issue happening to my iPad.... plus....when apps are opened they take too long too load up, at times there is a black screen, not just blank, but a black coloured screen. Than after waiting for it to open, after a few minutes of using the app (any app) or if I put my iPad to sleep to go do something else and go back to the app it is frozen and can not be used... so I must close it, so either by four finger swipe up or double clicking the home button and closing app and reopening it to work. This happens while reading emails as well. What about iCloud account not working, rejecting the password that works on an iPhone but not on the iPad! Annoying! Has anyone escalated these problems so that the Apple people do something about it. My iPad also gets real hot...this has been happening from the first time I purchased it, this has not stopped it still heats up, I have called and spoken to apple about it, around 3 or 4 times, but they keep saying its normal, but it's not...other friends that have iPads, and I have quite a few friends who do have an iPad, their iPads do not heat up like mine, and we would be at same meeting using our iPads! HELP US APPLE....)
Forgot to mention....multitasking gestures stop working...and that wifi gets disconnected on iPad to many times a day. the list is growing!! I think Apple is trying to get us to buy new iPada or iPhones, if they can add U2 album to your music list, then can do anything! I wonder....if we should all go get a windows based computer! My desktop is a dell..works just fine never had issues like these, -
Performance issue with iPhone 4 on iOS 7
Hello,
I have been using iPhone 4 since October 2011. Phone was performarming exceptionally good when it was running on iOS 6. However, post upgrading to iOS 7, finding all nonsense experieinces like any other Andriod/windows devices.
1. Phone hangs very frequently
2. Response time is rediculous (eventhough once I restart the device, performs better but cannot do it every now & then)
3. Applications stop responding & phone returns to home screen
Is this a common problem with all iPhone 4 users or specifically in India.
Also, want to know is there a possibility to go back to iOS 6 rather than running on iOS 7 & suffering with performance issues.Prasadhegde wrote:

Downgrading is not Supported by Apple.
For your Issues...
Try This...
Close All Open Apps... Sign Out of your Account... Perform a Reset... Try again...
Reset ( No Data will be Lost )
Press and Hold the Sleep/Wake Button and the Home Button at the Same Time...
Wait for the Apple logo to Appear...
Usually takes about 15 - 20 Seconds... ( But can take Longer...)
Release the Buttons...
If no joy...
Reset all settings
Settings > General > Reset > Reset all Settings.
This will return all iDevice settings to factory defaults... you will not lose any data.... But you will have to re-enter all of the device settings.
If the issue persists...

Performance issues after upgrading iPad 1 to IOS 5..
Apps open slower, lag in response and even typing gets an intermittent lag..
I have 51GB free space out of 64.. So not a space issue.
Is it an IOS5 issue with the iPad1 or could they be an upgrade issue? My iTunes hung several time during the upgrade.. So I wonder about that.
Do I try to revert back to 4 or should I stick with IOS5 and try to erase my iPad then sync over again?You can't revert back to iOS 4 officially - Apple does not support downgrades. You could try restoring your device or you could just try restarting it or resetting it if you haven't tried either of those things. I would try those things before I would restore.
Restart the iPad by holding down on the sleep button until the red slider appears and then slide to shut off. To power up hold the sleep button until the Apple logo appears and let go of the button.
Reset the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons.
I have an original iPad and I updated and other that a little keyboard lag - which I always had anyway in every iOS that was on the device - I have had no performance issues. -
I am using iphone 3gs, I upgraded my i-os to 6.0 from 5.1.1 however I am facing performance issue, along with this all the applications including settings or any other shuts down automatically. Is there any way by which I can use my phone in better way?
No, downgrading from any version of iOS to an earlier version is not supported.

Cisco ASR 1002- performance issue due to access list
Hi,
We are planning to implement inbound access-list to block subnets from particular country. Since the subnets are not contiguous, we have about 16000 lines of acl entries.
I want to know, would there be any performance or latency issues after applying 16k lines of acl?
Is there a good document where I can read more about ACL limitations and performance issues on ASR.
This is for ASR1002, running IOS-XE 15.3(1)S1.

Performance issue with calendar and applescript
Hi Community,
I have a performance issue using applescript and calendar with this script:
tell application "Calendar"
tell calendar "Cal"
set theList to (get {summary, start date, end date, uid} of events)
end tell
end tell
There are app. 700 events in the calendar "Cal". Therefore the get-command takes about 15 seconds. The problem is, that iCal is completely blocked for this time. This means it is even not possilbe to scroll through the calendar. This problem occurs only under OS X 10.9. With OS X 10.8.x it is still possible to use calendar even a time-consuming get-command is processed.
Any ideas? Maybe there is a way to reduce the task-priority of an applescript?I have to step in here...
1) Must I set "None" or "On Time"
- In order for the Calendar to fire an Alarm, it must know what time to fire the alarm. In the event of an All Day Event, it will go off at 12am. The option for "Repeat", below the "Alarm", states the frequency of the event (Daily, Weekly, Monthly, Yearly, etc). So to set an alarm that fires once a month, set the TIME you want the alarm to go off (Make sure "All Day" is unchecked if you want a specific time), then choose "On Time" for the "Alarm", and one of the several "Monthly" options for "Repeat". If I missed something in what you were asking, please let me know and I will do my best to more directly answer your question.
2) Calendar cannot sync with the Mac.
- Not directly. However, your phone automatically syncs with your Google Calendar, set up if you create your account. If you so choose, you may export your iCal calendar, import it into your Google calendar, and then use your Google calendar (http://calendar.google.com) to manage your agenda. The changes sync automatically with your device.
Once again, I hope this shed some light on things. To the Verizon rep who originally answered this question: I have no intention to bash you, however please bear in mind that your opinions and comments will always be held in higher regard than mine, so if you choose to answer a question, please try to solve the problem as opposed to just answer the question. I have experience with all manner of devices and operating systems, from WebOS to BB to iOS to Android, and I believe this phone has the best hardware coupled with a solid operating system in TouchWiz, and I don't want to see people frustrated with these devices by questions that get nothing more than, "You can't do that" answers from the people that are expected to support them. -
Report Performance Issue - Activity
Hi gurus,
I'm developing an Activity report using Transactional database (Online real time object).
the purpose of the report is to list down all contacts related activities and activities NOT related to Contact by activity owner (user id).
In order to fullfill that requirment I've created 2 report
1) All Activities related to Contact -- Report A
pull in Acitivity ID , Activity Type, Status, Contact ID
2) All Activities not related to Contact UNION All Activities related to Contact (Base report) -- Report B
to get the list of activities not related to contact i'm using Advanced filter based on result of another request which is I think is the part that slow down the query.
<Activity ID not equal to any Activity ID in Report B>
Anyone encountered performance issue due to the advanced filter in analytic before?
any input is really appriciated
Thanks in advanced,
FinaFina,
Union is always the last option. If you can get all record in one report, do not use union.
since all records, which you are targeting, are in the activity subject area, it is not nessecery to combine reports. add a column with the following logic
if contact id is null (or = 'Unspecified') then owner name else contact name
Hopefully, this is helping. -
Report performance Issue in BI Answers
Hi All,
We have a performance issues with reports. Report is running more than 10 mins. we took query from the session log and ran it in database, at that time it took not more than 2 mins. We have verified proper indexes on the where clause columns.
Could any once suggest to improve the performance in BI answers?
Thanks in advance,I hope you dont have many case statements and complex calculations that you do in the Answers.
Next thing you need to monitor is how many rows of data that you are trying to retrieve from the query. If the volume is huge then it takes time to do the formatting on the Answers as you are going to dump huge volumes of data. Database(like teradata) returns initially like 1-2000 records if you hit show all records then even db is gonna fair amount of time if you are dumping many records
hope it helps
thanks

What si the bottle neck (hardware) of Adobe Premiere Pro CS6
I used PPBM5 as a benchmark testing template.
All the data and log as been collected using performance counter
First of all, describe my computer...
Operating System
Microsoft Windows 8 Pro 64-bit
CPU
Intel Xeon E5 2687W @ 3.10GHz
Sandy Bridge-EP/EX 32nm Technology
RAM
Corsair Dominator Platinum 64.0 GB DDR3
Motherboard
EVGA Corporation Classified SR-X
Graphics
PNY Nvidia Quadro 6000
EVGA Nvidia GTX 680 // Yes, I created bench stats for both card
Hard Drives
16.0GB Romex RAMDISK (RAID)
556GB LSI MegaRAID 9260-8i SATA3 6GB/s 5 disks with Fastpath Chip Installed (RAID 0)
I have other RAID installed, but not relevant for the present post...
PSU
Cosair 1000 Watts
After many days of tests, I wanna share my results with community and comment them.
CPU Introduction
I tested my cpu and pushed it at maximum speed to understand where is the limit, can I reach this limit and I've logged precisely all result in graph (See pictures 1).
Intro : I tested my E5-XEON 2687W (8 Cores Hyperthread - 16 threads) to know if programs can use the maximum of it. I used Prime 95 to get the result. // I know this seem to be ordinary, but you will understand soon...
The result : Yes, I can get 100% of my CPU with 1 program using 20 threads in parallel. The CPU gives everything it can !
Comment : I put 3 IO (cpu, disk, ram) on the graph of my computer during the test...
(picture 1)
Disk Introduction
I tested my disk and pushed it at maximum speed to understand where is the limit and I've logged precisely all result in graph (See pictures 2).
Intro : I tested my RAID 0 556GB (LSI MegaRAID 9260-8i SATA3 6GB/s 5 disks with Fastpath Chip Installed) to know if I can reach the maximum % disk usage (0% idle Time)
The result : As you can see in picture 2, yes, I can get the max of my drive at ~ 1.2 Gb/sec read/write steady !
Comment : I put 3 IO (cpu, disk, ram) on the graph of my computer during the test to see the impact of transfering many Go of data during ~10 sec...
(picture 2)
Now, I know my limits ! It's time to enter deeper in the subject !
PPBM5 (H.264) Result
I rendered the sequence (H.264) using Adobe Media Encoder.
The result :
My CPU is not used at 100%, the turn around 50%
My Disk is totally idle !
All the process usage are idle except process of (Adobe Media Encoder)
The transfert rate seem to be a wave (up and down). Probably caused by (Encrypt time.... write.... Encrypt time.... write...) // It's ok, ~5Mb/sec during transfert rate !
CPU Power management give 100% of clock to CPU during the encoding process (it's ok, the clock is stable during process).
RAM, more than enough ! 39 Go RAM free after the test ! // Excellent
~65 thread opened by Adobe Media Encoder (Good, thread is the sign that program try to using many cores !)
GPU Load on card seem to be a wave also ! (up and down) ~40% usage of GPU during the process of encoding.
GPU Ram get 1.2Go of RAM (But with GTX 680, no problem and Quadro 6000 with 6 GB RAM, no problem !)
Comment/Question : CPU is free (50%), disks are free (99%), GPU is free (60%), RAM is free (62%), my computer is not pushed at limit during the encoding process. Why ???? Is there some time delay in the encoding process ?
Other : Quadro 6000 & GTX 680 gives the same result !
(picture 3)
PPBM5 (Disk Test) Result (RAID LSI)
I rendered the sequence (Disk Test) using Adobe Media Encoder on my RAID 0 LSI disk.
The result :
My CPU is not used at 100%
My Disk wave and wave again, but far far from the limit !
All the process usage are idle except process of (Adobe Media Encoder)
The transfert rate wave and wave again (up and down). Probably caused by (Buffering time.... write.... Buffering time.... write...) // It's ok, ~375Mb/sec peak during transfert rate ! Easy !
CPU Power management give 100% of clock to CPU during the encoding process (it's ok, the clock is stable during process).
RAM, more than enough ! 40.5 Go RAM free after the test ! // Excellent
~48 thread opened by Adobe Media Encoder (Good, thread is the sign that program try to using many cores !)
GPU Load on card = 0 (This kind of encoding is GPU irrelevant)
GPU Ram get 400Mb of RAM (No usage for encoding)
Comment/Question : CPU is free (65%), disks are free (60%), GPU is free (100%), RAM is free (63%), my computer is not pushed at limit during the encoding process. Why ???? Is there some time delay in the encoding process ?
(picture 4)
PPBM5 (Disk Test) Result (Direct in RAMDrive)
I rendered the same sequence (Disk Test) using Adobe Media Encoder directly in my RamDrive
Comment/Question : Look at the transfert rate under (picture 5). It's exactly the same speed than with my RAID 0 LSI controller. Impossible ! Look in the same picture the transfert rate I can reach with the ramdrive (> 3.0 Gb/sec steady) and I don't go under 30% of disk usage. CPU is idle (70%), Disk is idle (100%), GPU is idle (100%) and RAM is free (63%). // This kind of results let me REALLY confused. It's smell bug and big problem with hardware and IO usage in CS6 !
(picture 5)
PPBM5 (MPEG-DVD) Result
I rendered the sequence (MPEG-DVD) using Adobe Media Encoder.
The result :
My CPU is not used at 100%
My Disk is totally idle !
All the process usage are idle except process of (Adobe Media Encoder)
The transfert rate wave and wave again (up and down). Probably caused by (Encoding time.... write.... Encoding time.... write...) // It's ok, ~2Mb/sec during transfert rate ! Real Joke !
CPU Power management give 100% of clock to CPU during the encoding process (it's ok, the clock is stable during process).
RAM, more than enough ! 40 Go RAM free after the test ! // Excellent
~80 thread opened by Adobe Media Encoder (Lot of thread, but it's ok in multi-thread apps!)
GPU Load on card = 100 (This use the maximum of my GPU)
GPU Ram get 1Gb of RAM
Comment/Question : CPU is free (70%), disks are free (98%), GPU is loaded (MAX), RAM is free (63%), my computer is pushed at limit during the encoding process for GPU only. Now, for this kind of encoding, the speed limit is affected by the slower IO (Video Card GPU)
Other : Quadro 6000 is slower than GTX 680 for this kind of encoding (~20 s slower than GTX).
(picture 6)
Encoding single clip FULL HD AVCHD to H.264 Result (Premiere Pro CS6)
You can look the result in the picture.
Comment/Question : CPU is free (55%), disks are free (99%), GPU is free (90%), RAM is free (65%), my computer is not pushed at limit during the encoding process. Why ???? Adobe Premiere seem to have some bug with thread management. My hardware is idle ! I understand AVCHD can be very difficult to decode, but where is the waste ? My computer want, but the software not !
(picture 7)
Render composition using 3D Raytracer in After Effects CS6
You can look the result in the picture.
Comment : GPU seems to be the bottle neck when using After Effects. CPU is free (99%), Disks are free (98%), Memory is free (60%) and it depend of the setting and type of project.
Other : Quadro 6000 & GTX 680 gives the same result in time for rendering the composition.
(picture 8)
Conclusion
There is nothing you can do (I thing) with CS6 to get better performance actually. GTX 680 is the best (Consumer grade card) and the Quadro 6000 is the best (Profressional card). Both of card give really similar result (I will probably return my GTX 680 since I not really get any better performance). I not used Tesla card with my Quadro, but actually, both, Premiere Pro & After Effects doesn't use multi GPU. I tried to used both card together (GTX & Quadro), but After Effects gives priority to the slower card (In this case, the GTX 680)
Premiere Pro, I'm speechless ! Premiere Pro is not able to get max performance of my computer. Not just 10% or 20%, but average 60%. I'm a programmor, multi-threadling apps are difficult to manage and I can understand Adobe's programmor. But actually, if anybody have comment about this post, tricks or any kind of solution, you can comment this post. It's seem to be a bug...
Thank you.Patrick,
I can't explain everything, but let me give you some background as I understand it.
The first issue is that CS6 has a far less efficient internal buffering or caching system than CS5/5.5. That is why the MPEG encoding in CS6 is roughly 2-3 times slower than the same test with CS5. There is some 'under-the-hood' processing going on that causes this significant performance loss.
The second issue is that AME does not handle regular memory and inter-process memory very well. I have described this here: Latest News
As to your test results, there are some other noteworthy things to mention. 3D Ray tracing in AE is not very good in using all CUDA cores. In fact it is lousy, it only uses very few cores and the threading is pretty bad and does not use the video card's capabilities effectively. Whether that is a driver issue with nVidia or an Adobe issue, I don't know, but whichever way you turn it, the end result is disappointing.
The overhead AME carries in our tests is something we are looking into and the next test will only use direct export and no longer the AME queue, to avoid some of the problems you saw. That entails other problems for us, since we lose the capability to check encoding logs, but a solution is in the works.
You see very low GPU usage during the H.264 test, since there are only very few accelerated parts in the timeline, in contrast to the MPEG2-DVD test, where there is rescaling going on and that is CUDA accelerated. The disk I/O test suffers from the problems mentioned above and is the reason that my own Disk I/O results are only 33 seconds with the current test, but when I extend the duration of that timeline to 3 hours, the direct export method gives me 22 seconds, although the amount of data to be written, 37,092 MB has increased threefold. An effective write speed of 1,686 MB/s.
There are a number of performance issues with CS6 that Adobe is aware of, but whether they can be solved and in what time, I haven't the faintest idea.

Performance Issue for BI system
Hello,
We are facing performance issues for BI System. Its a preproductive system and its performance is degrading badly everyday. I was checking system came to know program buffer hit ratio is increaasing everyday due to high Swaps. So asked to change the parameter abap/buffersize which was 300Mb to 500Mb. But still no major improvement is found in the system.
There is 16GB Ram available and Server is HP-UX and with Netweaver2004s with Oracle 10.2.0.4.0 installed in it.
The Main problem is while running a report or creating a query is taking way too long time.
Kindly help me.Hello SIva,
Thanks for your reply but i have checked ST02 and ST03 and also SM50 and its normal
we are having 9 dialog processes, 3 Background , 2 Update and 1 spool.
No one is using the system currently but in ST02 i can see the swaps are in red.

this issue, and that our goal is to find out the root of the problem. But
first I'd like to narrow down the avenues by process of elimination.
Open Cursor is something that is commonly used in today's RDBMS. I
know that you must test your query in ISQL using some kind of execute
immediate, but Sybase should be able to handle an open cursor. I was
wondering if your Sybase expert commented on the fact that the server is
not responding to commonly used command like 'open cursor'. According to
our developer, we are merely following the API from Sybase, and open cursor
is not something that particularly slows down a query for several minutes
(except maybe the very first time). The logs show that Forte is waiting for
a status from the DB server. Actually, using prepared statements and open
cursor ends up being more efficient in the long run.
Some questions:
1) Have you tried to do a prepared statement with open cursor in your ISQL
session? If so, did it have the same slowness?
2) How big is the table you are querying? How many rows are there? How many
are returned?
3) When there is a hang in Forte, is there disk-spinning or CPU usage in
the database server side? On the Forte side? Absolutely no activity at all?
We actually have a Sybase set-up here, and if you wish, we could test out
your database and Forte PEX here. Since your queries seems to be running
off of only one table, this might be the best option, as we could look at
everything here, in house. To do this:
a) BCP out the data into a flat file. (character format to make it portable)
b) we need a script to create the table and indexes.
c) the Forte PEX file of the app to test this out.
d) the SQL staement that you issue in ISQL for comparison.
If the situation warrants, we can give a concrete example of
possible errors/bugs to a developer. Dial-in is still an option, but to be
able to look at the TOOL code, database setup, etc. without the limitations
of dial-up may be faster and more efficient. Please let me know if you can
provide this, as well as the answers to the above questions, or if you have
any questions.
Regards,

We did that trick already.
When it is hanging, I can see what is doing.
It is doing OPEN CURSOR. But not clear the exact statement of the cursor
it is trying to open.
When we run the query directly to Sybase, not using Forte, it is clearly
not opening any cursor.
And running it directly to Sybase many times, the response is always
consistently fast.
It is just when the query runs from Forte to Sybase, it opens a cursor.
But again, in the Forte code, Alex is not using any cursor.
In trying to capture the query,we even tried to audit any statementcoming
to Sybase. Same thing, just open cursor. No cursor declaration anywhere.==============================================

Like:
- a database version
- how did you test
- what data do you have, how is it distributed, indexed
and so on.
If you want to find out what's going on then use a TRACE with wait events.

Is there a recommended limit on the number of custom sections and the cells per table so that there are no performance issues with the UI?
Thanks Kelly,
The answers would be the following:
1200 cells per custom section (NEW COUNT), and up to 30 custom sections per spec.
Assuming all will be populated, and this would apply to all final material specs in the system which could be ~25% of all material specs.
The cells will be numeric, free text, drop downs, and some calculated numeric.
Are we reaching the limits for UI performance?
Thanks
