How to know the Performance effect when swapping or changing Containers ??

Hi ,
As part of Custom Item Renderer to a DataGridColumn , i am having this code below :
<mx:HBox id="jai">
        <mx:Image source="images/canvas.png" visible="true" height="100%" width="100%"/>
        <mx:Label id="kkk" text="Pavan"/>
        <mx:Button label="Edit" click="openPopUpWindow()"/>
    </mx:HBox>
But unfortunately , this doesn't give me a pleasant look , so i decided to use Panel
instead of HBox , Means this way
<mx:Panel id="jai">
        <mx:Image source="images/canvas.png" visible="true" height="100%" width="100%"/>
        <mx:Label id="kkk" text="Pavan"/>
        <mx:Button label="Edit" click="openPopUpWindow()"/>
    </mx:Panel>
I am also worried about the Performance of the Application at the same time .
Please tell me as how can i know or confirm that Changing the Container from HBox to Panel
didn't affected anything performance wise or not ??
Thanks .

Use the performance profiler. We typically use 3 to 5 runs, looking for
convergence around a range of times.

*Shocked* by the performance of Canon DPP, and DDP workflow with Aperture

I love Aperture. My brother mercilessly hounded me for two years, and when Aperture 2 came out, I gave it a shot. Aperture 3, despite my nightmare conversion story, has been a dream come true . . . until I discovered sharpening.
In my quest to get sharper photos, I've toyed with image stabilization, tripods, higher shutter speeds, steadying the camera, and depth of field, and even bought several professional lenses. My photos STILL did not look as sharp as those I saw in galleries and online. But wait . . . my JPEG files from my sporting events did . . .
I read that RAW files are not sharp, and sharpening is applied to JPEGs on the camera. But why is Aperture and my MBP not able to sharpen photos well using any one of the three sharpening sliders or the sharpening tool? I was then led to DPP, kicking and screaming. What I discovered was truly amazing.
Forget about the personal opinions with warmth and contrast between Aperture, ACR, and DPP. DPP is the unquestioned leader in producing sharp photos from RAW images. You drag the slider . . . it's sharp. It's even sharper than the photos I've spent 20 minutes sharpening in CS5 with sharpening masks, sharpening tool, etc. The DPP tool JUST WORKS. Even noise with high ISO is MUCH improved. High noise still can use an expensive tool to correct, but still MUCH better than Aperture.
Until Canon reveals their secrets to Apple and Adobe for RAW processing, I need to figure out a way to use DPP for RAW processing.
For those that use DPP for RAW processing, how to you work it into your workflow? I want Aperture to be a one-stop shop, but I don't want to store the original RAW, the DPP-edited RAW, and potentially a TIFF for additional editing and noise reduction?
Do you sort in Aperture first? Do you convert in DPP first? How do you maintain file integrity, and at the same time, minimize disk space usage?
If you no longer use DDP, please tell me why, and how you've worked around it?

All I can say is, either I've been in the weeds all this time, or your skills with sharpening are better than most.
A couple of questions:
1-What do you use under Sharpening for and Edges under "RAW fine tuning" you thankfully shared your settings for Edge Sharpen (^s)
2-What camera and RAW format are you using (this may help me fine-tune my preferences). I've got a 7D and primarily shoot MRAW. (Not the best for a couple reasons, but I don't need or want the large file sizes.)
To be sure, default sharpening in Aperture is pretty bad. And I have played with sharpening going on 40 hours now over several months. I could not get a good result.
Your documenting the exact settings and sharpening tool is what helped me get past whatever I was doing before. Maybe I was thrown by the higher default contrast in DPP. I'm now able to produce a better result in Aperture than DPP, or even my laboriously-sharpened photos on Photoshop. There are some tradeoffs in each, but I didn't want to use DDP as part of my workflow. Now that I've used it more, I'm convinced I don't!
And the definition setting is very useful. It's the only mainstream adjustment I've never really used.

Help to asses the performance impact of OAS and WLS integration.

If this is not the right forum, please direct me to the right one for the below clariafication.
We have developed a small application using ADF technology and this application can be integrated with the existing EBS R12 application. So, the EBS R12 application will be running in Oracle Application Server and ADF application will be running in WebLogic Server. And the customer who is implementing this, would like to know the below impacts before they start to implement.
1) Oracle Application Server to Web Logic Server (WLS) Connection happens to view the ADF application, What would be Resource Consumption of WLS to handle this ADF application. They would like to know the WLS resource used by this ADF application.
2) How does the Network/Data Traffic impact the Utilization of Web Logic Server and Oracle Application Server.
Could you please help us in providing the feedback to the customer.
Ans Is there a way to do load testing in our internal development instance to asses the resource consumption, cpu usuage and the network traffic?
Thanks,

Could some one help us?

How to Improve the Performance of SQL Server and/or the hardware it resides on?

There's a particular stored procedure I call from my ASP.NET 4.0 Web Forms app that generates the data for a report. Using SQL Server Management Studio, I did some benchmarking today and found some interesting results:
FYI SQL Server Express 2014 and the same DB reside on both computers involved with the test:
My laptop is a 3 year old i7 computer with 8GB of RAM. It's fine but one would no longer consider it a "speed demon" compared to what's available today. The query consistently took 30 - 33 seconds.
My client's server has an Intel Xeon 5670 Processor and 12GB of RAM. That seems like pretty good specs. However, the query consistently took between 120 - 135 seconds to complete ... about 4 times what my laptop did!
I was very surprised by how slow the server was. Considering that it's also set to host IIS to run my web app, this is a major concern for me.
If you were in my shoes, what would be the top 3 - 5 things you'd recommend looking at on the server and/or SQL Server to try to boost its performance?
Robert

What else runs on the server besides IIS and SQL ? Is it used for other things except the database and IIS ?
Is IIS causing a lot of I/O or CPU usage ?
Is there a max limit set for memory usage on SQL Server ? There SHOULD be and since you're using IIS too you need to keep more memory free for that too.
How is the memory pressure (check PLE counter) and post results.
SELECT [cntr_value] FROM sys.dm_os_performance_counters WHERE [object_name] LIKE '%Buffer Manager%' AND [counter_name] = 'Page life expectancy'
Check the error log and the event viewer maybe something bad there.
Check the indexes for fragmenation, see if the statistics are up to date (and enable trace flag 2371 if you have large tables > 1 million rows)
Is there an antivirus present on the server ? Do you have SQL processes/services/directories as exceptions ?
There are lot of unknowns, you should run at least profiler and post results to see what goes on while you're having slow responses.

Can I take the titles effect Horizontal Blur and add it to my png logo?

Hello everyone,
I really like the horizontal blur effect (well at the moment I do). Can I add that effect to my logo?
I have tried copy/paste attributes & effects, but the effect does not show up. I've looked on line for suggestions
but nothing refers to copy/pasting text fx only video fx etc.
Any thoughts, comments or suggestions will be appreciated.
Thanks in advance and have a great day!

TS2932 Aperture 3.5.1 thumbnail picture shows normal. When I click on the image to view full screen the filter effect is gone and all images appear really dark and almost blue in tone. I also have photos that are distorted. The faces are out of proport

Thumbnails appear normal. But the master image is totally wrong...

No. Also, There seems to only be one project that is doing this... here's a screen shot of another project that appears normal.

I bought all the new effects from retrica around Christmas time and I had to factory reset my phone and now their not there and say I have to purchase all of them again please tell me how I can get my purchases back

I bought all the new effects for Retrica and now they say I have to purchase them all again

Dr Traed-
There should be a program that came with the camera that can view the AVCHD videos. It may have the ability to save-as other formats.
One program that is good for converting some video formats to M4V or MP4 required by iPad, is HandBrake. <Download Handbrake> If you can save the videos to an intermediate format, HandBrake may be able to complete the comversion to MP4.

Clarification regading the performance of REGEXP functions

I was asked to do a performance comparison between the REGEXP functions in perl and the one in oracle database .
I am using Oracle 11.1.0.6 version database for the same .
Here is the sample code that I used to replace fragements in a string with appropriate values .
"code" is the string and I'm replacing sub-strings inside it which are wrapped within $$ symblos with the appropriate values("repl_value") from the Associative array ("name_value").
code VARCHAR2(4000) := 'INSERT /*+ APPEND */ INTO $$T:LOCATIONS[1]$$($$C:LOCATIONS[1]:LOCATION_ID[1]$$,$$C:LOCATIONS[1]:LOCATION_CODE[1]$$,$$C:LOCATIONS[1]:ADDRESS[1]$$)SELECT $$S:LOCATIONS_S[1]$$.nextval,UNIQ_LOCATION_CODE,US FROM ( SELECT DISTINCT $$C:DEPT[1]:LOCATION_CODE[1]$$uniq_location_code FROM   $$T:DEPT[1]$$ dpt WHERE $$C:DEPT[1].LOCATION_CODE[1]$$ NOT IN ( SELECT $$C:LOCATIONS[1].LOCATION_CODE[1]$$ FROM   $$T:LOCATIONS[1]$$ loc2)) uniq_loc';
BEGIN
WHILE (REGEXP_SUBSTR(code,'\$\$') IS NOT NULL) LOOP
              value := REGEXP_SUBSTR(code,'\$\$[^\$]*\$\$');
              value := REGEXP_REPLACE(value,'\$\$.*?([_[:alnum:]]+)(\[1\])?\$\$','\1');
              repl_value := name_value(value);
              code := REGEXP_REPLACE(code,'\$\$[^\$]*\$\$',repl_value,1,1);
        END LOOP;The code was working fine and I tried running the code 100000 times and it took around 6 minutes .
I also coded the same in perl and for the same 100000 times it took only 20 seconds .
I just want to know whether I have introduced any piece of code which acts as a performance bottleneck ? Let me know whether the pl/sql coding I have done is effective or not ?

We have a xml file where these code fragments will be within the tags . I have to get these code fragments and replace the strings wrapped in $$ symbols with the appropriate object names from the staging dictionary .
For this we are analyzing the performance using various methods and I was asked to test it in pl/sql and perl . I just created a proto-type where I am hard-coding the values in associative array and passing them to a function which replaces the fragments in the string with values of the associative array . Since the tables were present in the database I thought there would be no question about Pl/sql high performance but using regexp in perl proved to be many times faster than pl/sql .
Thats why I just wanted to clarify if there is any performance bottlenecks in the way I have coded in pl/sql . Can someone help me regarding this ?

Absolute value in ckf, performance effect?

Hello BW Experts,
req: always show positive values for one kf1 of a cube, even if you have negative values for kf1.
options:
create a ckf1 with the absolute value of kf1
-- 1) are there any other options in the backend or frontend?
-- 2) what are the performance effects of the abosolute function option as compared to having a kf in the cube.?
Suggesions appreciated.
Thanks,
BWer

Hi,
You can multiply the values with -1 on the backend side or in the query itself there is an option of reversing the sign in the settings.

Graph axes assignment: performance difference between ATTR_ACTIVE_XAXIS and ATTR_PLOT_XAXIS

Hi,
I am using a xy graph with both x axes and both y axes. There are two possibilities when adding a new plot:
1) PlotXY and SetPlotAttribute ( , , , ATTR_PLOT_XAXIS, );
2) SetCtrlAttribute ( , , ATTR_ACTIVE_XAXIS, ) and PlotXY
I tend to prefer the second method because I would assume it to be slightly faster, but what do the experts say?
Thanks!
Solved!
Go to Solution.

Hi Wolfgang,
thank you for your interesting question.
First of all I want to say, that generally spoken, using the command "SetCtrlAttribute"is the best way to handle with your elements. I would suggest using this command when ever it is possible.
Now, to your question regarding the performance difference between "SetCtrlAttribute" and "SetPlotAttribute".
I think the performance difference occures, because in the background of the "SetPlotAttribute" command, another function called "ProcessDrawEvents" is executed. This event refreshes your plot again and again in the function whereas in the "SetCtrlAttribute" the refreshing is done once after the function has been finished. This might be a possible reason.
For example you have a progress bar which shows you the progress of installing a driver:
"SetPlotAttribute" would show you the progress bar moving step by step until installing the driver is done.
"SetCtrlAttribute" would just show you an empty bar at the start and a full progress bar when the installing process is done.
I think it is like that but I can't tell you 100%, therefore I would need to ask our developers.
If you want, i can forward the question to them, this might need some times. Also, then I would need to know which version of CVI you are using.
Please let me now if you want me to forward your question.
Have a nice day,

A significant difference between the metrics captured at Proxy and BS level

Context: -
          Currently we have following set up for a particular OSB project.
AccountManager
          Interface …… (this has all the schemas and wsdls)
          Services
               AccountManagerProxy… (Proxy service)
               AccountManagerBS … (Business service)
AccountManagerBS – is configured with end point URL to interface with back-end system.
AccountManagerProxy – includes a ‘Route to’ action for linking to AccountManagerBS as given below
The performance monitoring is enabled at AccountManagerProxy and AccountManagerBS level.
Test Scenario: - I am running a simple load test for AccountManager and checking performance metrics from OSB dashboard.
Expected behavior: - The performance metrics at proxy and at BS level should not differ more than few milliseconds (10-50 msec)
Problem Statement: - I am seeing a significant difference (like 40 to 50 seconds) between the metrics captured at proxy and BS level.
     As an example, the number at proxy level is “1 minute 20 seconds” and the number at BS level is ‘500 milliseconds’
     Moreover, this behavior is not consistent. It has started showing this behavior in last few days. The further impact of this is ‘stuck threads’ on webLogic server and hence the high possibility of memory outage. I have already restarted the Admin/managed-1/managed-2 servers couple of times.
Can anyone help me understand and identify the exact problem area for this issue?

does your proxy do any authentication with any 3rd party auth providers ?
Also in proxy service monitoring are you seeing all time at route node ? .. is the business service request type different that the contents of $body before the route? .. there could be some implicit transofmations if yes...
