Hgrid - Expand all Performance Issue

Hi all,
I am facing a performance leak on a "Expand All" event of a Hgrid (implemented as dynamic hgrid).
For a particular page, the application opens the hgrid in collapse mode. It takes less than 1 second.
But, when the user clicks on "Expand All", it takes 3 minutes to show all records (around 600 records in my case).
The Jserv log shows the View link query execution using prepared statement mutiple times.
The view link is created on 4 fields using the Same View Object.
Can anyone please suggest, how can I reduce the time consumed in expanding the hgrid?
Any pointers appriciated.
Regards.

Hi,
I know its very late, just want to share our experience. We had same problem with HGrid, at times we had more than 5000 parent/childs and page takes around 10 mins to load. We opened a SR with oracle and its been a year for now and is still in WIP :).
Thanks

Performance Issue in UNION ALL....

Hi,
I have a performance issue in a query using select.. union all .
There are few select statements which are joined by union all.
I need to re-frame the query such that the records from each individual select
statement can be appended into a collection variable.
I need to avoid the use of UNION ALL.
Can anyone please help me out in this issue?
Please find the select statement below.
SELECT *
FROM v_gfd1_asset_allocation
WHERE NVL(value,0) <> 0
AND scheme = p_scheme_id
UNION ALL
SELECT *
FROM v_gfd1_capitalization_alloc
WHERE NVL(value,0) <> 0
AND scheme = p_scheme_id
UNION ALL
SELECT *
FROM v_gfd1_currency_allocation
WHERE NVL(value,0) <> 0
AND scheme = p_scheme_id
Thanks,
Santhosh

The UNION ALL takes the result set of one query, appends the result set of the next, and so forth. No sorting or filtering takes place. So, as each query has to be executed to completion, I do not think there is another way - that is what union all is for.
You would probably do well to examine each query's access path. Would an index on NVL( value, 0 ), scheme help, for instance? Understanding the data distribution in the table and how it affects the execution plan would help you improve query performance.

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.

Is it possible to remove collapse all and expand all links in HGrid.

Hi All,
Is there any way to remove collapse all and expand all links which HGrid shows by default, the reason is when the user clicks on collapse all it will collapse to root node but my requirement is it should collapse untill 2 node level.
Thanks
Babu

From the javadoc of OAHGridBean
======================
void setExpandAllEnabled(boolean expandAllEnabled)
Indicate whether the "Expand All" (and "Collapse All") links should be rendered for the HGridBean.

Ganesh

Performance issue ! all java guru invited

hi !
plz let me know is there any performance related difference between these two approachs
mention below.
Ist
public void method1()
for(int i=0;i<20;i++)
String temp = "str"+i;
myObject mobj = new myObject();
2nd
String temp="":
myObject mobj=null;
public void method1(){
for(int i=0;i<20;i++)
temp = "str"+i;
mobj = new myObject();
}

Find out! Get the loop to run 20000 times and time each using System.currentTimeMillis(). Repeat this several times for each, throw away the highest and lowest couple of results and average the rest. Compare this between the two approaches.
Regardless, the performance difference is likely to be minor, if any, compared to the construction and allocation of memory for the new Objects. I would hope that most reasonable compilers would be able to deal with these anyway.
Performance issues aside, many people prefer the former approach since each local variable doesn't outstay its welcome. This makes debugging and refactoring more straightforward. As with all optimisations, it's not worth making them at the expense of clarity if they make no real difference.
Test the performance of your code, in the context of your application, in realistic circumstances. You'll soon find out where your effort should be spent on optimisations.
Hope this helps.

WEBUTIL - Does adding it to all forms cause performance issues?

If I add the webutil library and object library to all forms in the system (as part of a standard template) despite the fact most won't use it, will this cause any performance issues???
Thanks in advance...

The webutil user guide has a chapter on performance considerations. Have you looked at that?
The number one point from that chapter is:
1. Only WebUtil Enable Forms that actually need the functionality. Each form that is WebUtil enabled will generate a certain amount of network traffic and memory
usage simply to instantiate the utility, even if you don’t use any WebUtil
functionality.

Performance issue BPC 7.5 SP4

Hi
We have got performance issue after a upgrade from BPC 7.5 SP03 to BPC 7.5 SP04 Patch1.
We got problem with EVDRE reports especially with large reports with a lot of settings in MemberSet or if we use filter on property in MemberSet.
We have reports that expand in about 20 seconds on BPC 7.5 SP03 and takes about 25 minutes to expand after the upgrade to BPC 7.5 SP04 Patch1
I have also made new EVDRE reports and vary simple reports works fine but when I increase the number of members to expand and the number of terms in MemberSet I works very slow.
We have got about 10 applications in this Appset and the problem does only occur in one of this Applications
I have processed all dimensions in the application and done full process and modify application without any error.
I have also tried to create a log file on the EVDRE report to compare logs in the different applications and different ServicPacks but I only get data in the EVDRE_TRACE.TXT file and no data in the EVDRE_LOG.TXT file
Anyone having the same problem? Anyone who knows how to get the EVDRE_LOG.TXT file to work?
Regards
Fredrik

Hi,
Starting with 7.0 SP4 enable the logs is done into other way.

Macbook screen cracked, HD and performance issues

I am definitely disappointed with my computer.
I have a Macbook 13.3" 2.4Ghz Intel Core 2 Duo 4Gb 160Gb HD, Serial#: W8**VM0P5, and within 1,5 year I have faced many issues, which are related here:
September 24th, 2008
O.S. CRASHES
I bought it in late September 2008, in Cologne, Germany, at the reseller "Compustore PC Gmbh", and also asked 4Gb Ram, and a Wireless mighty mouse.
After changing the Ram memory, i went home; and a few days later, the problems came. Sometimes, the system crashed suddenly, showing the grey screen: "You must restart your computer". I thought it was normal, and continued to use, when it became more frequently (Picture: http://picasaweb.google.com/gstorck/MacbookProblems#5476986272817173138). It was little strange for a new laptop, and then I took it back to the store to fix it. The seller just took a look, changed some configurations, and gave me back again. I did this twice, and had to get back to the store for the third time, due to new crashes and some lack of performance. Then the seller replaced the Ram memory, with new 4Gb.
After that, the system worked more stable; the problem happened some two or three times after some months, but it was ok.
November 9th, 2009
HD Problems
One year later, in late 2009, I purchased a Mac OS update, the Snow Leopard. I was back to Brazil, where I live till today. During the OS installation, something went wrong and it couldn't be completed. Mac asked me to restart the computer, but then the system didn't start anymore; some files were corrupted. I guess there was not enough space to install the update, so it was not completed; but it should be no reason to the corruption of the OS.
November 10th, 2009
I took my computer to the local Apple technical support, the "Omni Informatica", in Curitiba, PR, Brazil, to format the HD and reinstall the Snow Leopard. As I needed more space, I also changed my original 160Gb HD for a new 250Gb Western Digital HD. The service was finished in Nov 17th.
I noticed also little cracks in the laptop case, but I had no time to insist with the bad local technical support to repair it (I know Apple already acknowledged this problem.) They said, at first, that they would have to ask the Apple USA to send the body, or something like that.
(Pictures:http://picasaweb.google.com/gstorck/MacbookProblems#5476986477312032226)
January 12th, 2010.
SCREEN CRACKED
The reinstallation was ok, and the laptop was running well. Suddenly, when I take the Macbook from the case and open it on my desk, something pretty wrong appears: a large crack on the lower right corner of the screen.
It was not dropped, it was not crashed, and I did not "close it with a pen inside".
The screen simply cracked. And as so many similar problems with another users I could easily find on the web, I really expect Apple to admit it as a Manufacture's fault. The local technical support said it is no other thing except I hit the laptop, or dropped it, so it's all my fault. (See Picture 3)
The only thing they can offer me is to repair the screen for R$1200. I am definitely not going to pay for this; a "normal" and good pc laptop costs this price (And a new basic macbook costs today R$2400).
If the problems were just it, it would be not so bad.
(Pictures: http://picasaweb.google.com/gstorck/MacbookProblems#5476986361400585122)
February 11th, 2010
HD FAILURE
After 1 month, on Feb 11th, my new 250Gb HD simply stopped working. Different from the first time, that the HD was just corrupted, this time it has really broken, it died. I had it all backed up, but I have lost the HD.
Back again to the technical assistance, they said to me the problem was the same that cracked my screen: my fault, on letting the laptop fall, or hitting it with some kind of pressure. They couldn't do anything, and even the Western Digital 3-month Warranty would not cover this type of problem ("user's misuse").
May 28th, 2010
DECREASE IN PERFORMANCE
I'm working again with the original 160Gb HD (formatted and reinstalled), and some other external drives to store my files.
It's been quite difficult to deal with all this Data and Screen problems, and now the Macbook's performance is decreasing every day. It's been slower to process operations and to launch the applications. Sometimes, the system does not even sleep anymore when the laptop is closed, or it takes so long time to sleep that it just sleeps when I open it again. Besides, sometimes the mouse pointer disappear, and some bizarre graphics take its place.
Don't forget: It's a 1,5-year-old Macbook, with 2.4GHz, 4Gb RAM and the O.S. is installed for no longer than 4 months. It is supposed to work better, I guess.
I saved a lot of money to buy a good computer, and to get rid of the endless issues I had with PCs. That issues never were so serious with the ones I face now with Macbook.
Even if I pay R$1200 to replace the screen, with the money I don't have, I would still stand these performance issues, which seem to have come with this problematical laptop. I hope to have some solution from Apple, if it want to deliver what it promises and want to keep a customer.
Otherwise, I will have to change to another system platform and another computer manufacturer, to see if I stop throwing money away with these devices. I think that maybe at least, the cost-benefit ratio will be higher.
Did anybody receive contact from Apple support about these screen problems?

Well, your first issue is pretty clearly just some bad RAM, and it sounds like even the replacement RAM was bad. Who knows if the people who put it in had any kind of clue what they were doing. I've seen repair shops where people are smoking in the same room they do repairs.
Second problem sounds typical of a failing HDD. It's a fairly common problem with laptops... Apple, Dell, Lenovo, HP, Acer... Probably the single most common problem with laptops no matter who makes them. People get this notion in their heads that the "portable" aspect of laptops means you can pick them up and carry them all over while turned on. Which you can... If you don't mind dramatically shortening the life of the HDD. What "portable" REALLY means with laptops, is that they are easy to move if you put them into a powered down state. They should NEVER be moved around when in normal operation. And since you seem to do a bit of traveling, if you're on a plan, and there's turbulence, you should shut the laptop off until it smooths out.
The screen cracking could have something to do with the rather sudden change in climate. Germany isn't exactly the frozen tundra, but it is a pretty different climate from Brazil, and changes in things like humidity could cause problems. The laws of thermodynamics tell us that things expand as they heat up, so if there's already a crack somewhere, it could easily get worse as a result of increased heat.
And since your initial hard drive was already starting to fail, it hasn't magically stopped failing since being removed from the system, so obviously performance is going to get worse.
At this point, it's pretty much impossible to tell where the damage was done, so you're probably just out of luck. The people in Germany could have screwed something up, or the people in Brazil, it could have been environmental damage, and it's possible the defect was always there, it just didn't manifest until recently. There's just no way to tell for sure. So Apple is unlikely to do anything for you.

Urgent Performance Issue

Hi,
Can someone please tell me and explain me that if i have performance issue at the portal side then what cache settings i have to choose at rsrt and then at the reporting agent level.
I will appreciate if you can explain me also in detail.
I will appreciate and award points.
Thanks
Sakshi

Hi Sakshi,
For your question pls read the following document carefully, so you will know the correct information,
regarding your question.
<b>Read Mode</b>
The read mode determines how the OLAP processor gets data during navigation. Three alternatives are supported:
1. Read when navigating/expanding the hierarchy
In this method, the system transports the smallest amount of data from the database to the OLAP processor but the number of read processes is the largest.
In the "Read when navigating" mode below, data is requested in a hierarchy drilldown for the fully expanded hierarchy. In the "Read when navigating/expanding the hierarchy" mode, data in the hierarchy is aggregated by the database and transferred to the OLAP processor from the lowest hierarchy level displayed in the start list. When expanding a hierarchy node, the system intentionally reads this node's children.
You can improve the performance of queries with large presentation hierarchies by creating aggregates in a middle hierarchy level that is greater than or equal to the start level.
2. Read when navigating
The OLAP processor only requests the data required for each query navigation status in the Business Explorer. The data required is read for each navigation step.
In contrast to the "Read when navigating/expanding the hierarchy" mode, the system always fully reads presentation hierarchies at tree level.
When expanding nodes, the OLAP processor can read the data from the main memory.
When accessing the database, the system uses the most suitable aggregate table and, if possible, aggregates in the database itself.
3. Read everything at once
There is only one read process in this mode. When executing the query in the Business Explorer, the data required for all possible navigation steps for this query is read to the OLAP processor's main memory area. When navigating, all new navigation statuses are aggregated and calculated from the main memory data.
The "Read when navigating/expanding the hierarchy" mode has a markedly better performance in almost all cases than the other two modes. This is because the system only requests the data that the user wants to see in this mode.
The "Read when navigating" setting, in contrast to "Read when navigating/expanding the hierarchy", only has a better performance for queries with presentation hierarchies.
In contrast to the two previous modes, the "Read everything at once" setting also has a better performance with queries with free characteristics. The idea behind aggregates, that is working with pre-aggregated data, is least supported in the "Read everything at once" mode. This is because the OLAP processor carries out aggregation in each query view.
We recommend you choose the "Read when navigating/ expanding the hierarchy" mode.
Only use different mode to "Read when navigating/ expanding the hierarchy" in exceptional circumstances.
The "Read everything at once" mode can be useful in the following cases:
The InfoProvider does not support selection, meaning the OLAP processor reads significantly more data than the query needs anyway.
A user exit is active in the query that prevents the system from having already aggregated in the database.
If it is Useful informatin to u pls provide points.
have nice day.

Treeview datawindow with icon - performance issue

Hi all,
i have a treeview dw and have set the "use tree node icon" property with 2 different icons (bmp) at the first level (when the level is expanded or collapsed)
Then a different icon (ico) file is used for the second level
Unfortunately, this is causing a huge performance issue when i run the application.
If i disable the "use tree node icon" property, everything works fine.
Is there any known issues on the treeview dw with icons? any work around?
am using pb11.2
thanking you in advance,
-a

First question is which jdev version you are using?
I made a quick test and did not see a long busy state.
Run your app with -Djba.debugoutout=console as java option. You get more output in the log window, but may be some hint about what's going on.

Resize performance issue

I have a wierd performance issue. My application consists of a lot of Panels, VBoxes, and other containers which all have widths that are bound to the main Application's width using equations such as
<Panel width="100%">
<VBox width="{width * someRatio}" />
<VBox width="{width * (1 - someRatio) - 10}"/>
</Panel>
Now when I resize the application by expanding the width to the right, the performance isnt too noticable. But if I shorten the width by dragging to the left, then the program bogs down while the Panel's and VBox's slowly crawl to the left. Does this have something to do with motion tweening? Does anyone have some advice I can use to make my resizing more snappy? This is a business application, so smooth pretty motion comes a distant second to snappy responsiveness.

Try running it in the profiler to see what is going on. For sure, if you make it small enough the containers will have to try to put up scrollbars and what not so there will be more work to do.
You might also benefit from using constraintColumns instead of your binding expressions.

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

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.
