Smartform performance issue
HI floks
i did some development in new smartform its working fine but i have issue in data base performance is 76% . but i utilize similar below code with various conditions in various 12 places . is it possible to reduce performance this type of code . check it and mail me how can i do it . if possible can suggest me fast .how much % is best for this type of performance issues.

Hi,
you can increase the performance by following,
1. By changing occurs clause to types declaration clause.
You need to declare like this:
DATA : BEGIN OF xVBRPC,
LV_POSNR LIKE VBRP-POSNR,
END OF xVBRPC.
DATA: ITVBRPC like table of xVBRPC,
2. do not use select statements in loop statements.

Smartforms - Performance Issue
Hi,
I am developing a report related to customer ageing details which involves high volume of transactional data.
Initially the report was displayed using ALV , but the client was not satisfied when they print the alv report in 130 col printer with sort and sub-total features.So I developed a smartform according to the required design.
Since the report involves page break and totals inbetween...i have used the event and At new command in the loop within the smartform..
The issue here is...when the report was tested with actuall data(high volume)..it took almost 5 times of the time when the report was executed using ALV..this is due to the design of the smartform involving the loops...
Is there any way to check out the performance of smartforms.Kindly suggest.
Regards,
Thyagu,Hi Thyagu,
As ALV, smart forms are just ABAP, so you can use the runtime analysis (SE30, or ST12, or SAT) to see what makes it slow.
See SDN and official documentation for more information about runtime analysis

Convert smartform to PDF Convert_OTF - Performance Issue
Hi gurus,
We have a custom development for Compensation statement developed smartform that could have easily been done in Adobe PDF. The downside of this is ithat whenever we want to download to PDF, the program first coverts this smart form to PDF usinf funciton module "Convert_OTF" and then downloads it.
Did any one face this performance issue. Is the convert to OTF a major time consuming process
We are having system performance issue when downloading the comp statement and want to analysize how big this CONVERT_OTF is a factor.
please suggestOk
Iìve never had particular performance problem with that function, so:
have you tried to measure the time for the printing (smartform), for the convertion (convert_otf) and for the downloading separatly?

Performance issue with Adobe forms
Dear SAP Experts,
We have the following issue/requirement from our client. The client is on SAP ECC 6.0 - production environment.
The client is highlighting performance issue while accessing the adobe forms for HR and FI business process ( both static and interactive ).
Examples are
FI – Invoice Approvals
HR – Job Salary Change
The client is asking us to provide best practices surrounding:
1. How to improve the performance of the adobe forms while accessing in SAP.
2. Is there any other technology which we can use in SAP to replace the adobe forms which has better performance factor.
3. Are there solutions such as webdynpro floor plan manager, UI Fiori which can be alternately used?
Regards,
SakthiHello Priya,
Adobe forms are easy to develop and much more comfortable than SAP Scripts and Smartforms. Initially they are a bit difficult but once you have your hands on, they are the most simplest things in ABAP.
Performance in Adobe forms is a mix of both fine tuning the Layout as well as back end coding.
Performance in Adobe forms cannot be done overnight. A lot of care has to be taken during the initial stage of development.
As far as my experience is concerned, please consider the below points while developing SAP Adobe forms.
1) Avoid Scripting (Javascript/Formcalc) as much as possible inside the form. It drastically reduces the performance and makes the form to execute slower. If you still want to use scripting(which cannot be avoided for some requirements), use Formcalc since it is comparatively faster than JavaScript.
2) Try to avoid the coding inside the Form Interface. You can always handle the maximum coding in the Driver program and pass it to the form.
3) Use Form Caching.
For forms that have fixed layout, its a good way to increase the performance of form rendering. In the layout, go to Form Properties. Then Click on Defaults tab and select Allow Form Rendering To Be Cached On Server. Then Click OK.
For forms that have flowable or dynamic layout, render the forms on the client side because it improves performance.
Last but not the least, please go through the below post by Otto Gold which is worth a read at least once.

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

This is the question we will try to answer...
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.

RE: Case 59063: performance issues w/ C TLIB and Forte3M
Hi James,
Could you give me a call, I am at my desk.
I had meetings all day and couldn't respond to your calls earlier.

Subject: Re: Case 59063: performance issues w/ C TLIB and Forte 3M
Hello,
I just want to reiterate that we are very committed to working on
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,

issues
w/ CTLIB and Forte 3M
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.==============================================

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 -
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.

Miska SavelaHi
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

Returning multiple values from a called tabular form(performance issue)
I hope someone can help with this.
I have a form that calls another form to display a multiple column tabular list of values(needs to allow for user sorting so could not use a LOV).
The user selects one or more records from the list by using check boxes. In order to detect the records selected I loop through the block looking for boxes checked off and return those records to the calling form via a PL/SQL table.
The form displaying the tabular list loads quickly(about 5000 records in the base table). However when I select one or more values from the table and return back to the calling form, it takes a while(about 3-4 minutes) to return to the called form with the selected values.
I guess it is going through the block(all 5000 records) looking for boxes checked off and that is what is causing the noticeable pause.
Is this normal given the data volumes I have or are there any other perhaps better techniques or tricks I could use to improve performance. I am using Forms6i.
Sorry for being so long-winded and thanks in advance for any help.Try writing to your PL/SQL table when the user selects (or remove when deselect) by usuing a when-checkbox-changed trigger. This will eliminate the need for you top loop through a block with 5000 records and should improve your performance.
I am not aware of any performance issues with PL/SQL tables in forms, but if you still have slow performance try using a shared record-group instead. I have used these in the past for exactly the same thing and had no performance problems.
Hope this helps,

On googling this seems to be an issue with java file handling on windows servers and I couldn't find a solution yet. Any recommendation or pointer is appreciatedHi shubhu,
I just analyzed your partial Thread Dump data, the problem is that the ajax4jsf framework ResponseWriterContentHandler triggers internally a new instance of the DocumentBuilderFactory; every time; triggering heavy IO contention because of Class loader / JAR file search operations.
Too many of these IO operations under heavy load will create excessive contention and severe performance degradation; regardless of the OS you are running your JVM on.
Please review the link below and see if this is related to your problem.. This is a known issue in JBOSS JIRA when using RichFaces / ajaxJSF.
