Performance Issues / Concerns

I have to use 213 tables in the universe designer. The database schema is oracle. What kind of issues/concerns should I consider before designing the universe. I appreciate your help.

Hi ,
The first thing you should consider is that do you really need this many tables in Your Universe ??
Follow the foolowing steps Before designining :
1) Have a clear scope define for Universe , i.e You are designing Universe for Sales Or Marketing or Human Resource etc .
2) Once you know the Scope and Target Audience and purpose is clear then segregate the tables based on your scope i.e define the scope of tables inside your schema
3) Clearly have all the reorting requiremnet in place
Then go for normal design procedure

Performance issue: Java and XSLT

I have a performance issue concerning Java and XSLT: my goal is to transform an xml file (source.xml)
by using a given xsl file (transformation.xsl). As result I would like to get a String object, in which the result
of the transformation (html-code) is in, so that I can display it in a browser. The problem is the long time
it takes for the code below to run through.
xml = new File("C:\\source.xml");
xmlSource = new StreamSource(xml);
xslt = new File("C:\\transformation.xsl");
StreamSource xsltSource = new StreamSource(xslt);
TransformerFactory transFact = TransformerFactory.newInstance();
trans = transFact.newTransformer(xsltSource);
StringWriter stringWriter = new StringWriter();
StreamResult streamResult = new StreamResult(stringWriter);
trans.transform(xmlSource, streamResult);
String output = stringWriter.toString();
stringWriter.close();
Before, I made the same transformation in an xml development environment, named Cooktop
(see http://xmlcooktop.com/). The transformation took about 2 seconds. With the code above in Java it
takes about 20 seconds.
Is there a way to make the transformation in Java faster?
Thanks in advance,

I haven't tried it but the if you can use java 6, you could try the new stax (StAX) with the XML stream loading..
Take a look at:
http://javaboutique.internet.com/tutorials/staxxsl/
Then, you could cache the xslt in templates:
---8<---
templates = transformerFactory.newTemplates( xsltSource );
Transformer transformer = templates.newTransformer();
(here you could probobly also cache the Transformer object but I think it's it's not thread safe so it's a little tricker..)
StreamResult result = new StreamResult( System.out );
transformer.transform(xmlSource, result);
And, don't transform your result to a string, use a Stream or something, then the transformer could start pumping out html while working, and if you get a out of memory error it looks like you have a pretty big xml file...
If you use jsp you could try the build in jsp taglib for xml which I think is rather good and they have support for varReader which implements the StreamSource iirc.

Performance Issue with BSIS(open accounting items)

Hey All,
      I am having serious performance issue with a accrual report which gets all open GL items, and need some tips for optimization.
The main issue is that I am accesing large tables like BSIS, BSEG, BSAS etc without proper indexes and that I am dealing with huge amounts of data.
The select itself take a long time and after that as I have so much data overall execution is slow too.
The select which concerns me the most is:
SELECT zuonr hkont gjahr belnr buzei budat blart wrbtr shkzg xblnr waers bukrs
             INTO TABLE i_bsis
              FROM bsis
              WHERE bukrs = '1000'
              AND hkont in r_hkont
              AND budat <= p_lcdate
              AND augdt = 0
              AND augbl = space
              AND gsber = c_ZRL1
              AND gjahr BETWEEN l_gjahr2 AND l_gjahr
              AND ( blart = c_re      "Invoice
              OR    blart = c_we      "Goods receipt
              OR    blart = c_zc      "Invoice Cancels
              OR    blart = c_kp ).   "Accounting offset
I have seen other related threads, but was not that helpful.
We already have a secondary index on bukrs hkont and budat, and i have checked in ST05 that it does use it. But inspite that it takes more than 15 hrs to complete(maybe because of huge data).
Any Input is highly appreciated.
Thanks

Thank you Thomas for your inputs:
You said that R_HKONT contains several ranges of account numbers. If these ranges cover a significant
portion of the overall existing account numbers, then there is no really quick access possible via the
BSIS primary key.
Unfortunately R_HKONT contains all account numbers.
As Rob said, your index on HKONT and BUDAT does not help much, since you are selecting "<=" on
BUDAT. No chance of narrowing down that range?
Will look into this.
What about GSBER? Does the value in c_ZRL1 provide a rather small subset of the overall values? Then
an index on BUKRS and GSBER might be helpful.
ZRL1 does provide a decent selection . But I dont know if one more index is a good idea on overall
system performance.
I assume that the four document types are not very selective, so it probably does not pay off to
investigate selecting on BKPF (there is an index involving BLART) and joining BSIS for the additional
information. You still might want to look into it though.
I did try to investigate this option too. Based on other threads related to BSIS and Robs Suggestion in
those threads I tried this:
SELECT bukrs belnr gjahr blart budat
FROM bkpf INTO TABLE bkpf_l
        WHERE bukrs = c_pepsico
        AND bstat IN (' ', 'A', 'B', 'D', 'M', 'S', 'V', 'W', 'Z')
        AND blart IN ('RE', 'WE', 'ZC', 'KP')
        AND gjahr BETWEEN l_gjahr2 AND l_gjahr
        AND budat <= p_lcdate.
SELECT zuonr hkont gjahr belnr buzei budat blart wrbtr shkzg xblnr waers bukrs
           FROM bsis INTO TABLE i_bsis FOR ALL ENTRIES IN bkpf_l
                     WHERE bukrs = bkpf_l-bukrs
                      AND hkont IN r_hkont
                      AND budat = bkpf_l-budat
                      AND augdt = 0
                      AND augbl = space
                      AND gjahr = bkpf_l-gjahr
                      AND belnr = bkpf_l-belnr
                      AND blart = bkpf_l-blart
                      AND gsber = c_zrl1.
The improves the select on BSIS a lot, but the first select on BKPF kills it. Not sure if this would help
improve performance.
Also I was wondering whether it helps on refreshing the tabe statistics through DB20. The last refresh
was done 7 months back. How frequently should we do this? Will it help?

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,
Sakthi

Hello 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.
How to write a messy form

Deployment of WLC-5508 with 2702i-D have performance issue.

Hi Team,
We have centrally deployed WLC-5508 with 50 AP licence along with HA scenario. we have 3 locations.
1- HQ. have 26 AP with POWINJ5.
2- Branch location A- 8 AP with POWINJ5.
3. Branch location B have 8 AP with POWINJ4.
my exception is to achieve that single SSID with dynamic VLAN from group police (NPS). MY HO have 26 AP and those are working in local mode.
and branches are connected through flexconnect mode. and all are working with different-2 NPS.
Now i am facing a problem with this deployment are following.
1- branch A have performance issue.
2- HQ have performance issue.
3- i don't want to go with dedicated NPS for every location.
In order to achieve this deployment i want only single SSID with primary and secondary NPS at my HQ with dynamic VLAN for respective departmental users vlans..
above is my problem and concern. otherwise i am successfully achieving this solution with dedicated NPS with single group policy. but when i am going forward to achieve my expectation that time i am facing authentication issue at my HQ and sometimes am not able to get proper VLAN IPs. at my HQ.
kindly help me in that to understand where I am doing wrong things to achieve my expectation.
Thanks.
Nalin

I am facing 2 different problems.
1st issue- in existing setup we have throughput issue. (while downloading or uploading any data from the internet or Intranet, that time wireless clients are facing slowness of the Speed. and same time when i am trying from LAN i am not facing any issue)
2nd Issue- I want to achieve only single SSID with primary and secondary NPS (AD group is bind with vlan Attributes) with dynamic VLAN for respective departmental users.
for Issue no 2 i have created SSID to achieve the single ssid parameter for every location. in order to achieve i have change all access points mode local to Flexconnect mode after that i have created AP groups location wise and then create flexconnect Groups where i have mapped all the vlan through AAA VLAN-ACL mapping. created interface group and mapped all the vlans in that group.
for more understanding please go through the below mentioned CLI view.

Database performance issue (8.1.7.0)

Hi,
We are having tablespace "payin" in our database (8.1.7.0) .
This tablespace is the main Tablespace of our database which is dictionary managed and heavily accessed by the user SQL statements.
Now we are facing the database performance issue during the peak time (i.e. at the month end) when no. of users use to run the no. of large reports.
We have also increased the SGA sufficiently on the basis of RAM size.
This tablespace is heavily accessed for the reports.
Now my question is,
Is this performance issue is because the tablespace is "dictionary managed" instead of locally managed ?
because when i monitor the different sessions through OEM, the no. of hard parses is more for the connected users.
Actually the hard parses should be less.
In oracle 8.1.7.0 Can we convert dictionary managed tablespace to locally managed tablespace ?
by doing so will the problem will get somewhat resolve ? will it reduce the overhead on the dictionary tables and on the shared memory ?
If yes then how what is procedure to convert the tablespace from dictionary to locally managed ?
With Regards

If your end users are just running reports against this tablespace, I don't think that the tablespace management (LM/DM) matters here. You should be concerned more about the TEMP tablespace (for heavy sort operations) and your shared pool size (as you have seen hard parses go up).
As already stated, get statspack running and also try tracing user sessions with wait events. Might give you more clues.

Insert performance issue with Partitioned Table.....

Hi All,
I have a performance issue during with a table which is partitioned. without table being partitioned
it ran in less time but after partition it took more than double.
1) The table was created initially without any partition and the below insert took only 27 minuts.

2) Now I re-created the table with partition(range yearly - below) and the same insert took 59 minuts.
Is there anyway i can achive the better performance during insert on this partitioned table?
[ similerly, I have another table with 50 Million records and the insert took 10 hrs without partition.
with partitioning the table, it took 18 hours... ]

I'm concerned about the view in step 2 and the index join in step 3. A composite index with both columns might eliminate the index join and result in fewer read operations.
If you know which partition the data is going into beforehand you can save a little bit of processing by specifying the partition (which may not be a scalable long-term solution) in the insert - I'm not 100% sure you can do this on inserts but I know you can on selects.
The APPEND hint won't help the way you are using it - the VALUES clause in an insert makes it be ignored. Where it is effective and should help you is if you can do the insert in one query - insert into/select from. If you are using the loop to avoid filling up undo/rollback you can use a bulk collect to batch the selects and commit accordingly - but don't commit more often than you have to because more frequent commits slow transactions down.
I don't think there is a nologging hint :)
So, try something like
insert /*+ hints */ into ...
Select
     A.Ing_Acct_Nbr, currency_Symbol,
     Balance_Date,     Company_No,
     Substr(Account_No,1,8) Account_No,
     Substr(Account_No,9,1) Typ_Cd ,
     Substr(Account_No,10,1) Chk_Cd,
     Td_Balance,     Sd_Balance,
     Sysdate,     'Sisadmin'
From Ideaal_Cons.Tb_Account_Master_Base A,
     Ideaal_Staging.Tb_Sisadmin_Balance B
Where A.Vendor_Acct_Nbr = Substr(B.Account_No,1,8)
   And A.Vendor_Cd = b.company_no

----Constraints and Performance issues----

Hi all,
I have a major concern and I would like ur suggestion on the best way to handle it.
I have a staging table cust_staging. I have 2 target tables customer, customer_address which must be populated from this staging table.
The customer key in all 3 tables is the primary key. For table customer_address, the customer_key is also referenced from the customer table.
Incremental data will be available in the staging table (aorund 0.2 million) and the customer table would have appx 2 million records.
The concern I have is that i have to insert/update this information into the target tables without disabling the foreign key constraints.
I tried to insert into both the target tables with the constraints enabled but the mapping just hangs and I am forced to kill the process. I had tried using a single mapping to populate both tables and when that was going into hang mode, i tried with first customer and then another mapping for customer_address. This also just goes on hang mode.
Next I tried to disable the constarint and enable it again in the mapping itself. My concern here is that if I do a blind insert and when I re-enable the constraints, if there is a violation, the target table may goto an unusable state and my target table will become non usable.
My concern here is how to tackle this problem. Can i first disable the constraints, incorporate some logic using the pre-mappings wherein I can apply business rules to check the constraints explicitly and then redirect the bad records to reject and other records to the actual target.
Please do let me know how I should handle this situation in OWB bearing in mind the performance issues also.
we use owb 9.2.

AT&T USBConnect Lightning performance issues with Snow Leopard

I recently purchased the AT&T USBConnect Lightning wireless data adapter and attempted to install it on my 15" MBP but ran into global network performance issues afterward so I wanted to check with anyone here who may have the same adapter. I noticed that the adapter has software drivers preloaded on the device that need to be installed on my Mac. Looking at the notes, it refers only to Mac OSX 10.4.11 or better and no mention of Snow Leopard so I'm now very concerned. The notes state that once the drivers are installed, that I'm required to reboot my computer which leads me to think the drivers may have affected MTU and other settings that might also impact performance with my other network adapters.
Appreciate any feedback you might have with this scenario.
Thanks so much!

Major Performance Issues in Flash 8

I have been experiencing major slowdown in the Flash 8
authoring tool... I am working with large files (about 40-50mb
.fla).
My system specs aren't too bad but maybe not enough?
1.5Ghz Pentium M
512mb RAM
1024mb virtual memory...
Is there anything that specifically causes Flash to slow way
down? I'm thinking about tweaking my system (either settings or by
upgrading hardware) but I don't know what would help Flash with
larger projects. I'm assuming that more RAM would speed things up,
but I don't want to jump to that assumption and buy it without
knowing for sure...
...any ideas?

Yes... more graphics = heavier load...
...obviously.
However the performance issues here I'm talking about aren't
just slight slowdown issues. It is a MAJOR slowdown problem that
occurs suddenly. This means that once I hit a certain filesize,
Flash slows down and will not respond for MINUTES. If it were a
simple "you added more graphics" problem, then it would show a
gradual decrease in performance.
What I was really wanted to know is what is the weak link
concerning Flash performance? Is it RAM, processor speed, or
something else?
I can upgrade, but I'm not buying a new multi-processor
machine...it's not feasible, and not to mention it's a huge
overkill.

Performance issues - slowdowns...

Hi all,
Brand new iMac 20 inch Core 2 Duo. Working super for the first couple of days and now I notice some performance issues.
First of all, I had some crashes with Safari today. I had installed the Flip4Mac wmv add-on a few days ago. So, I deleted the Flip4Mac WMV browser plugins as suggested in the forums here and no crashes since.
However, Safari now takes a while to load if starting from "closed". The first few days, it opened much, much faster.
Also now iCal is slow to load (almost freezing system with the spinning colour wheel bussing about). It eventually loads, and works as expected - but the first few days it was super fast to load up.
Finally, I have noticed some other occasions where the system just becomes unresponsive. I still have mouse control (not a hard lock up), but I can't switch between programs or launch a new one. Waiting 10-20 seconds usually does the trick and I am again able to work as expected.
I am new to Macs after years as a PC user. In fact, I have a new MacBook Pro coming next week as well. Needless to say, I have made the switch by jumping in! So, I am learning a whole new world here and could use some help! I sure would like to retain the amazing performance I witnessed the first few days, so any assistance is most appreciated.
Best,
Stu

Allan's suggestions may be better than what I'm going to offer so I'd try them first. If gentler methods don't help, you may want to consider more drastic measures. As he pointed out, brand new hardware is not always perfect.
If you can easily back up all the data you have, I'd consider doing that, then do an erase and install. To do this, boot your Mac, insert the system install or restore disk that came with your Mac, restart, and hold down the C key right after it chimes. When you run through the installation prompts, click the Options Tab when you see it and choose erase and install, remembering that this will wipe out data you have not backed up elsewhere. (not trying to be condescending, just covering all the bases).
There could be some sort of small easy-to-fix issue that Allan's tips will fix. If, OTOH, there is a hardware issue, doing and erase and install will clear up that question pretty quickly. The erase and install will put you back to "factory condition" as far as software is concerned. If problems develop again in a day or two (or sooner) then you should call Apple. Just don't forget to mention you've already done an erase and install.
good luck
Jeff

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,
Fina

Fina,
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.
