LineTo on MouseMove has performance issue on scaled display object

Here is the scenario:
1. on mouse down on a canvas, start handling MouseMove event
2. on Mouse Move draw a line to the current mouse position
When the above processes run, the result is a descent enough
line being drawn on the canvas.
Now if we programatically scale the canvas' parent the
MouseEvent handler seems to be called less often, and the line
becomes less smooth.
This reduction in quality/performance only occurs when the
scale factor of the canvas' parent is between 1.5 and 3.3, anything
above or below this range works fine. - this is stumping us all!?
&%$£*@!
Any help, pointers, ideas, would be much apreciated.
Thanks,
Osh...

Hi,
Using a variable on the BW side is not feasible since we want to use the same BW query for a few other reports as well.
Could you please explain what you mean by 'use LAG function'.How can it be used in this scenario?
Thanks and Regards,

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,

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.==============================================

Query Performance Issue based on the same Multiprovider

Hi All,
I am facing a performance issue with one of the BEx Query 1 based on a particular Multiprovider.
I have done all the kind of testing and came o a conclusion that the OLAP: Data Transfer time for the query is the max at around 820 Secs.
The surprising part is another Query 2 based on the same multiprovider runs absolutely fine without any hassles with OLAP : Data Transfer time with merely 3 Sec.
Another, surprise is that Query 2 has even more Restricted Key Figures and Calculated Key Figures but it runs smoothly.
Both the queries use cache memory.
Please suggest a solution to this.
Thanks.

Hi Rupesh,
There is no much difference between the 2 queries.
Query 1 - which has performance issue has the same filters as that of Query 2 - which is working fine.
The only difference is that the selection of Fiscal Week is in the Default Values Pane for Query 2 whereas its in Characteristics Restrictions in Query 1. I doubt whether this setting will have any effect on the performance.
Both restriction i.e Fiscal Week restriction is based on Customer exit and the rows include Hierarchy for both the queries.
I assume creating aggregates on hierarchy for the Cube can be a solution.

11.2.0.0 upgrade- performance issue when commits

We have upgraded our data warehouse system from 10.2.0.4 for 11.2.0.2. After upgrade ETL system has performance issue. Extraction is fine because we compared the explain plans before and after upgrade. However, loading is taking very long. In loading there is a commit after every 1000 records, that why its slow. Even when we import data with commit=y option its very slow. Is there any know issue on this?
Any help pl?
Thanks

We are solaris 10. ETL job on 10.2.0.3 was taking 2 hours and now its taking 11 hours.
I beleive commit is a issue because
1. Source query (Extraction) has same explain plan.
2. Source database is still on 10.2.0.3
3. Servers and network is same for 10g and 11g.
4. I already experienced COMMIT=y performance issue in import.
Thanks

Performance issue working with OciArray

We have an performance issue with Oracle Spatial objects, e.g. SDO_GEOMETRY.
To get data from an Oracle Array (OciArray) there is functionality like:
OciNumberToRealArray
which is performing much better than doing
OciNumberToReal
for each instance.
But now we are sending an SDO_GEOMETRY to Oracle, so during the bind process we currently do:
for each number
do
OciNumberFromReal
OciCollAppend
enddo
We noticed that for the overall query, including getting the result, it is spending approx
6.3% in OciNumberFromReal
7.4% in OciCollAppend
On average we are sending 1500 values, so we are talking a lot of calls here.
Now since there is a way to get things from an array a lot faster using API's:
OCICollGetElemArray
OCINumberToRealArray
I am wondering why there is no way to set/put values into an array, like in:
OciNumberFromRealArray
or perhaps better
OciNumbersFromRealArray
I also noticed that there is no way of getting integer values from an array directly, you can only get one integer value at a time.
So there is no equivalent like:
OciNumberToIntArray
(there is OciNumberToInt and OciNumberFromInt)
Is no one experiencing this kind of stuff?
Regards,
Patrick

能提高多少性能？我怎么使用不成功，下面是部分代码，nOrdiCount是集合中元素总个数，m_pGeometry是一个GEOMETRY对象，执行OCICollGetElemArray之后，nOrdiCount的值被覆盖了。是oracle里面的代码把它覆盖了，我可以用这段代码去6个元素，超过6个元素，执行OCINumberToRealArray就无法返回了，不知何故？
OCINumber** pArray = new OCINumber*[nOrdiCount];
uword nCount = nOrdiCount;
memset(pArray, 0, sizeof(OCINumber*)*nOrdiCount);
OCICollGetElemArray(pConn->m_hOCIEnv, pConn->m_hOCIError, m_pGeometry->sdo_ordinates, 0, &exists, (void**)pArray, NULL, &nCount);
OCINumberToRealArray(pConn->m_hOCIError, (const OCINumber**)pArray, nCount, sizeof(real), pOrdiateData);
*OrdiateCount += nCount;
delete []pArray;
补充：
的确能够提高性能，但是其中有bug，OCICollGetElemArray函数中把我的函数中局部变量（栈变量）覆盖了，里面应该是内存访问越界了，期待改进！

Performance issues with Motion (position, scale, rotate) and GTX 590

I'm experiencing performance issues with my Premiere Pro CC when I scale, position or rotate a clip in the program monitor.
I have no performance issues with playback! It's only, when i move something with the mouse or by changing the x,y-values of Position in the Motion-Dialog in video effects.
Premiere then lags terribly and updates the program monitor only about once per second - this makes it very difficult and cumbersome to work and position things.
On a second Premiere installation on my laptop, performance is fine and fluid - allthough it doesn't have GPU support and is a much slower computer.
I'm pretty sure this has somehow to do with my graphic card, which is a Nvidia GTX 590.
I was told by the support, that it is actually a dual graphic card, which is not supported/liked by Premiere.
The thing is, until the latest Premiere update, I did not have performance issues at all with this card.
I also read on the forum that others with the GTX 590 did not experience any problems with it
So where does this come from?
There is no change in performance whether or not I activate Mercury Playback Engine GPU acceleration.
I also tried deactivating one of the 2 gpus, but there also was no change.
Does anyone else know this problem and has anyone a solution?
I'm running Premiere CC on a Win 7 64bit engine, Nvidia GTX 590, latest driver (of today),

I am suffering from the same phenomenon since I updated just before christmas, I think.
I am hardly able to do scaling, rotating and translating in the program monitor itslef - whil motion has been highlighted in teh effect controls.
In the effect controls I can scale, rotate etc however.
Also I have noticed there is a yellow box with handles in teh program monitor. I remember it was white before.
I cannot figure out what to change in my preferences. What has happened?
best,

CAT4900M and NetApp - Performance issue

Hi,
I'm struggling with a performance issue between our two NetApp Fas3170-devices.
The setup is quite simple: Each NetApp is connected via two TenGig interfaces to a CAT4900M. The 4900M's are also connected via two TenGig interfaces. Each pair of connections are bundled into an Layer2-etherchannel, configured as a dot.1q trunk. Mode is set to 'ON' on both the 4900 and the NetApp. According to NetApp documentation, this configuration is supported. Across each etherchannel, the vlans 219 and 220 are allowed. Two partitions are configured on the NetApp's, one being active in our primary datacenter and another in our secondary datacenter. Vlan219 and Vlan220 are configured for each the two partitions, using HSRP for gateway redundancy.
None of the interfaces nor the etherchannels shows any signs of misconfiguration. All links are up and etherchannels working as expected, well almost. Nothing indicates packet loss, crc-errors, Input/Output queue-drops or anything the would impact performance. Jumboframe is not configured, although this has been discussed.
The problem is, that we're unable to achieve satisfactory performance, when for instance, performing a volume copy between the two NetApp partitions. Even though we have a teoretical bandwidth of 20Gbps end-to-end, we never climb above 75-80 Mbytes of actual transfer-rate between the two NetApps. So performancewise, is almost looks as if we're "scaled" down to a 1Gig link. No QoS or other kind of ratelimiting has been implemented on the 4900's, so from a network point of view, the NetApps can go full-throttle. NetApp sw has been updated and configurations for both NetApp and 4900's have been revised by NetApp engineers and given a "clean bill of health".
The configuration for the 4900->NetApp etherchannel/interfaces is as follows:
interface TenGigabitEthernet1/5
description *** Trunk NetAPP DC1 ***
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 219,220
switchport mode trunk

Hi,
Thanks for your reply.
I take it, that you mean baseline performance between the two NetApp's. Well, that's really out of my hands, as another department is responsible for the NetApp's. I'm not aware of any baseline performance, nor have I seen any benchmark tests or anything, that could give me hint.
Just as you suggest, I've gone through the switch-setup systematically. Basically, starting with the physical layer and working my way up. So far, I've found nothing that would indicate a physical problem. The switchport/etherchannel setup has been verified by my peers and also verified by NetApp according to the configuration on the NetApps, as well as the various best-practice documentation availible. Futhermore, I haven't seen any signs of packets drops, crc-errors, massive re-transmissions or anything like not, neither on the switches nor the NetApps.
Recently we had a status-meeting with our NetApp-partner and it looks to me like they're persuing the logical setup on the NetApps, as the're apparently a number of settings etc. that needs adjustment. Also, we're waiting for NetApp tech-support to comment on the traces, config-dump etc. we've send to them.

ODS performance issue.

We have an ODS which has been facing severe performance issues. The reason is mostly due to high number of writes during data capture from the mainframe, volume of data and the huge increase in the number of people/applications querying the database for operational planning, statistical analysis etc. One thing I noticed about this database is that there are a huge number of unused fields in each table. Some of the fields are not used at all, sometimes the data capture operation writes 30 or 40 whitespace to the field (no idea why). My question is : Will dropping these unnecessary fields improve performance ?
Edited by: Crusoe on Sep 18, 2012 2:00 PM

If we tell them to drop those 15 unused fields will the database performance improve significantly ?Why guess?
How can we know?
Further root cause analysis is required.
If you have system-wide performance problems, use a system-wide report like AWR or Statspack to investigate what the biggest issues are.
See http://jonathanlewis.wordpress.com/statspack-examples/ for advice on interpreting these reports.
For example if I have a single table with 20 fields and only 5 of them hold any meaningful data and the remaining 15 are just garbage. Let's say 10 hold null values and remaining contain 5 whitespace of differing length and there are about 70 write transactions per second. If we tell them to drop those 15 unused fields will the database performance improve significantly ?Who knows?
Will it have some effect? Probably?
Is it relevant to your issues? Who knows.
Are you even likely to notice the effect? I would GUESS not.
The reason is mostly due to high number of writes during data capture from the mainframe, volume of data and the huge increase in the number of people/applications querying the database for operational planning, statistical analysis etcZoom in on these areas individually
Trace these parts of the application.
What are these areas of the application waiting on?
Are there common themes to the issues in these specific areas?
Is it inadequate resources? Increasing hardware may not be relevant to your issue.
In fact, just upgrading hardware can make things worse.
Is it specific contention?
Is it bad design leading to inefficient ways to access the required data?
Do you use partitioning?
Have you read "scaling to infinity" by Tim Gorman? http://www.evdbt.com/papers.htm
Is partitioning even relevant to your issues?
Who knows?
Not us. Yet.
Oracle is very well instrumented.
There should be no need to guess and throw money at hardware before you know what the problem is.

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...

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 !

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 !

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).

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 !

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.

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.

Yoga 3 Pro Performance issue on streaming video

I recently purchased a Yoga 3 Pro despite serious concerns about the reviews citing such poor performance from Intels new M-core processors. I had read at some point in my searching that Intel was supposedly releasing a firmware update that would essentially fix everything. I have a suspision that my issues are related to the processor. The problem I'm having can best be described as performance drop, or fps drops when playing videos in Youtube and on Twitch.tv. I've tried multipled browsers, and updates to flash. The browser is the only program running. It does not come in waves or anything, it is a constant issue on these sites. Beta.twitch.tv however does not have this issue, I believe they switched away from flash-based players. Netflix also has no issues. The issue is not a buffering issue. Maximizing the video also makes the problem worse. If anyone has any ideas or solutions I would be very much appreciated. I love the laptop and would hate to have to return because I can't get a few small parts of it to work.
Thank you!

Hi snickers, and welcome to the Lenovo User Community!
Like you I read the performance reviews, so I've been trying to stretch the Yoga 3 Pro. For video I've watched YouTube, Netflix, and VUDU maximised at full screen. I've watched full-length movies. I just watched a few Twitch.tv videos. I have yet to experience any poor performance. My browser is 32-bit Chrome. I'm on a 50-100Mbps Internet connection and either 802.11n or ac.
What are the symptoms you're seeing? When you say fps drop, what are you seeing exaclty? Are you using factory default drivers?
I don't work for Lenovo. I'm a crazy volunteer!

Performance issues with LOV bindings in 3-tier BC4J architecture

We are running BC4J and JClient (Jdeveloper 9.0.3.4/9iAS 9.0.2) in a 3-tier architecture, and have problems with the performance.
One of our problems are comboboxes with LOV bindings. The view objects that provides data for the LOV bindings contains simple queries from tables with only 4-10 rows, and there are no view links or entity objects to these views.
To create the LOV binding and to set the model for the combobox takes about 1 second for each combobox.
We have tried most of tips in http://otn.oracle.com/products/jdev/tips/muench/jclientperf/index.html, but they do not seem to help on our problem.
The performance is OK (if not great) when the same code is running as 2-tier.
Does anyone have any good suggestions?

I can recommend that you look at the following two bugs in Metalink: Bug 2640945 and Bug 3621502
They are related to the disabling of the TCP socket-level acknowledgement which slows down remote communications for EJB components using ORMI (the protocol used by Oracle OC4J) to communicate between remote EJB client and server.
A BC4J Application Module deployed as an EJB suffers this same network latency penalty due to the TCP acknowledgement.
A customer sent me information (that you'll see there as a part of Bug# 3621502) like this on a related issue:
We found our application runs very slow in 3-Tier mode (JClient, BC4J deployed
as EJB Session Bean on 9iAS server 9.0.2 enterprise edition). We spent a lot
of time to tune up our codes but that helped very little. Eventually, we found
the problem seemed to happen on TCP level. There is a 200ms delay in TCP
level. After we read some documents about Nagle Algorithm, we disabled a
registry key (TcpDelAckTicks) in windows2000 on both client and server. This
makes our program a lot faster.
Anyway, we think we should provide our clients a better solution other than
changing windows registry for them, for example, there may be a way to disable
that Nagle's algorithm through java.net.Socket.setTcpNoDelay(true), in BC4J,
or anywhere in our codes. We have not figured out yet.
Bug 2640945 was fixed in Oracle Application Server 10g (v9.0.4) and it now disables this TCP Acknowledgement on the server side in that release. In the BugDB, I see backport patches available for earlier 9.0.3 and 9.0.2 releases of IAS as well.
Bug 3621502 is requesting that that same disabling also be performed on the client side by the ORMI code. I have received a test patch from development to try out, but haven't had the chance yet.
The customer's workaround in the interim was to disable this TCP Acknowledgement at the OS level by modifying a Windows registry setting as noted above.
See Also http://support.microsoft.com/default.aspx?kbid=328890
"New registry entry for controlling the TCP Acknowledgment (ACK) behavior in Windows XP and in Windows Server 2003" which documents that the registry entry to change disable this acknowledgement has a different name in Windows XP and Windows 2003.
Hope this info helps. It would be useful to hear back from you on whether this helps your performance issue.

Performance issues with dynamic action (PL/SQL)

Hi!
I'm having perfomance issues with a dynamic action that is triggered on a button click.
I have 5 drop down lists to select columns which the users want to filter, 5 drop down lists to select an operation and 5 boxes to input values.
After that, there is a filter button that just submits the page based on the selected filters.
This part works fine, the data is filtered almost instantaneously.
After this, I have 3 column selectors and 3 boxes where users put values they wish to update the filtered rows to,
There is an update button that calls the dynamic action (procedure that is written below).
It should be straight out, the only performance issue could be the decode section, because I need to cover cases when user wants to set a value to null (@) and when he doesn't want update 3 columns, but less (he leaves '').
Hence P99_X_UC1 || ' = decode(' || P99_X_UV1 ||','''','|| P99_X_UC1 ||',''@'',null,'|| P99_X_UV1 ||')
However when I finally click the update button, my browser freezes and nothing happens on the table.
Can anyone help me solve this and improve the speed of the update?
Regards,
Ivan

Hi Ivan,
I do not think that the decode is performance relevant. Maybe the update hangs because some other transaction has uncommitted changes to one of the affected rows or the where clause is not selective enough and needs to update a huge amount of records.
Besides that - and I might be wrong, because I only know some part of your app - the code here looks like you have a huge sql injection vulnerability here. Maybe you should consider re-writing your logic in static sql. If that is not possible, you should make sure that the user input only contains allowed values, e.g. by white-listing P99_X_On (i.e. make sure they only contain known values like '=', '<', ...), and by using dbms_assert.enquote_name/enquote_literal on the other P99_X_nnn parameters.

Christian
