Is connecing thru a datasource slower then handling connections thru code?

We have an application that connects to a database using the latest Oracle 10g thin drivers. When a connection is made the response from the database takes anywhere from 15 - 25 seconds. When we make a connection thru the code base using the same connect string it takes less then 1 second. Is this normal?
We see that the response comes back in 30 packet chunks over the network regardless of the size of the query, it just show up more the larger the query is. Is this 30 byte chunk set a WebLogic limitation? Can it be bypassed?

Is yours an external application, either making direct JDBC connections to the DBMS or using a WebLogic server and a WebLogic DataSource?
If so, then the result is expected. Going from application to weblogic and then to the DBMS is expected to be slower than going directly from application to DBMS.

Internet slowed, then random connectivity

So I purchased my MacBook roughly 2 years ago some time this month. It was fine for the first year and my dad didn't want to get AppleCare because nothing had happened to it yet. As I reached the end of my warranty, the internet connection started slowing down gradually. About three months after my warranty expired, my hard drive died. I had to shell out $100 for a new one and installation. At this point in time, my internet connection was at it's worse. It would show full signal strength to my router, however would not allow internet access. I called my ISP and had them reset it and my internet was not better. Thinking it was my router I went out and got another. With that router, I was able to achieve random connectivity whenever my MacBook felt like it. We have since purchased another router in the hopes that it would get better, but it didn't. It's stayed the same, or gotten worse. I can achieve internet through wired means, directly to the wall, but it's rather bothersome and defeats the purpose of having a laptop if you can't move it. If you think you know what the problem is, let me know. If you know how much the repair would be, let me know. If it's too high, as a simple look-over costs $50, I would rather purchase a new computer.

Mac mini Core Solo is a great deal slower then 1.5ghz mac mini G4??

I have two mac minis, one has a 1.5 Ghz G4 and the other has a 1.5 Ghz Core Solo. Both have 512mb of RAM and OS X 10.4.7. I have the same software installed between them. They both have the latest updates for Office 2004 installed, both have the latest system updates, latest Firefox updates, both have latest Adobe Reader updates, and both have Quark 6.5 installed.
The Core Solo mac mini is WAY slower then the G4, Entourage in particular is almost slow to the point it is unworkable. Is this due to the Rosetta emulation? What can I do to improve this, will increasing the ram to 1 GB clear these speed issues or am I going to have to return this mini and get one with a Core Duo?
The current sluggishness on the Core Solo mini is unbearable, literally my Powerbook G4 667mhz with 768mb of ram is loads faster then this mini is. I'm thinking more RAM will do the trick, but wanted to bounce this off of some other experts here first. Thanks.

Entourage in particular is almost slow to the point it is unworkable. Is this due to the Rosetta emulation?
Yes, almost certainly. Microsoft Office is not yet Intel-native, so it's gonig to run more slowly than a native edition would. The same will apply to any PowerPC-only software.
What can I do to improve this, will increasing the ram to 1 GB clear these speed issues
I can't say for certain, but other users have reported that increasing the RAM to 1GB (or beyond) has made significant improvements in performance.

Why is the SSD on 2011 Macbook Air much slower then 2010 Macbook Pro with Samsung 830 SSD (less then half the speed) ?

Why is a laptop designed from ground up to use flash slower then a older laptop with a upgraded SSD from a 3rd party?
My old MBP is more then 2x the speed (read/write) with a SSD upgrade (Samsung 830) then my Air.
Any fixes or mods to boost the flash speed of the Air?

We would like you to show us how to do that.......Especially when the Samsung 830 will not fit the Air.....Please don't say duct tape....
Ok, scratch that idea. Let me think for a moment,,,em,,,em. OK I got it. Sell both units and buy a mid Macbook Air 2012 version.

var MyXML:XML = new XML(MyXMLString);//Parse the XML ONCE
I have a function called ConvertXML , and to check the

for(var i:Number=0;i<100;i++){
var MyXMLArr:Array = ConvertXML(MyXML, false, false);
EndTime = getTimer();
trace(EndTime - StartTime + " ms");
and here is my code for parsing the variable MyXML in
ActionScript 3.0 (ConvertXML function)
quote:
//Action Script 3.0 ConvertXML
import flash.xml.*;
function ConvertXML(RecvXML:XML, ChildBranch:Boolean,

RowArr.push(TempObject);
return RowArr;
addEventListener(Event.ENTER_FRAME, RunXML);

actionscript 2.0 code

return RowArr;
this.onEnterFrame = RunXML;
they both does exactly the same thing.. and yet the
actionscript 3.0 code run 5~7 TIMES SLOWER . why?
i have tried other benchmark, and it seems that actionscript
3.0 perform 10 to 100 TIMES FASTER then actionscript 2.0 , only for
this one it run slower... why?
I also attach all the code for actionscript 3.0
should you want to try the actionscript 2.0 , just uncomment
the ConvertXML and this.onEnterFrame for actionscript 2.0 and
comment the one for actionscript 3.0
Why? have i done something wrong?
Cheers and God Bless,

Although this doesn't answer your specific question exactly,
it's worth noting that most of the time you do not need to convert
XML into an array or objects like it was helpful to do in AS2, as
XML is a native Object in AS3.
For instance, xml.M would give you an XMLList of logins that
would be treated the same was as your desired Array:
var logins:XMLList = xml.M;
trace(logins[0].Username) // "Test 1"
And that takes 0 milliseconds. ;) You can also declare you
XML directly in AS3, you do not need to declare it as a String and
parse it (see attached.)
Don't know what your trying to accomplish so that might not
help you, but I thought it was worth mentioning. I've been using
E4X extensively for the first time in a project and I have to say
that overall it's made life much easier for me.

Anyone notice that Firefox downloads and load a page a lot slower then Dolphin HD?

Anyone notice that Firefox downloads and load a page a lot slower then Dolphin HD? That has been my experience all morning. I'm on Verizon Droid 2.
I been testing various web pages using Dolphin & Firefox Mobile, and I have noticed that in general, web pages takes longer to download and slower to render in Firefox Mobile then in Dolphin HD. It is not a cache issue as I clear my cache between tries.
Firefox Mobile 4 (downloaded 3/21/2011)?
Dolphin HD 4.5.0

I have the same problem on my website. It only happens in Firefox. IE, Chrome and Safari are working fine.
Very strange behaviour. Check this page: http://1stlook.nl/webdesign-eindhoven.html
You have to push the orange button twice. First time it only drops. Only if you click in the right corner it works???

The Leopard interface is definitely more graphics intensive (and I have heard suggestions that Leopard transfers more work to the graphics card than earlier versions of OSX). I guess at some level of hardware any processing efficiencies will be outweighed by the load on the graphics card. In other words, can you be sure that your results would replicate on a PPC machine with a more powerful graphics card and more VRAM?

AEBSn 5.0 slower then AEXPress G

Past requests for help in Discussions have been great BUT it seems that every so often performance via AEBSn goes south.
1. AEBSn using 5.0 for my MacBook Pro. My wife's Powerbook is using Airport Express that is hardwired in to AEBSn and set up as BRIDGE (per Express recommendation.
2. Our IP is feeding house at 5614 kbps download and 953 upload. My wireless feed from AEBSn is 1454/616 which is SLOWER then when I access via Airport Express (1578/634)
3. Both units are set to determine CHANNEL automatically. In the past I have manually checked all the channels for performance on the Express (time consuming)but the AEBSn using 5.0 will only allow Automatic
4. Both AEBSn and Express use WEP Personal.
5. In the past I have been able to get very good speeds off both AEBSn and Express, in fact almost as good as hard wired. For the last couple of days it is very slow and erratic.
6. I have iStumbler but am not sure how to use it other then checking channels.
Question: Could I have AEBSn and Express incorrectly setup? Any suggestions?
Always appreciate input.
David

Hi Tingi... interesting however,
*your point 2.*: You _won't be able to change the frequency/channel (it is 36 I believe)_ for 802.11n@5Ghz. t seems set that way.
Just as a suggestion, AS A TRYOUT, why not BACK the base stations to 802.11N @ 2.4Ghz and give tha a try.
I have experienced the situation you have ages ago and it was related to signal peneration between base statsion.. for me at least.
I isolated it and ended up buying another APX 11.n .. *how I get 270-300Mbs on a 802.11N @ 5Ghz*.
Anyway just try the 802.11n@ 2.4Ghz.. you sould get 130Mbs (thats 130Mbs) .. certainly a load more than 6Mbs.!!
However you wifes PB G4 may is certainly 802..1G or earlier. My wife has an 12inches (300mm) PB 887Mhz and it connects at 802.11g at 36Mbs MAX.. so ok for small timemachine updates &adn net surfing and emails.
Post your reults.

11.9 very slow then 11.7

Flash player 11.9 (last version) too, too, TOO SLOW then 11.7 (or earlier 11.9). Shaders works very slow in windows player's plug-in Why? What's happen? I'm the developer and this is very important for me! Is it bug or ...?

Emerging security research related to Virtual Machines and Just-In-Time compilers compelled us to disable the JIT compilation for old-school Pixel Bender shaders. We did not take this decision lightly as we try to never break backwards compatibility; however, we feel that in this instance, it was the right move in terms of protecting customers and end-users.
We recommend that you migrate your shaders to Stage3D and AGAL (aka Pixel-Bender 3D).
You can find more information about Stage3D and AGAL here: http://www.adobe.com/devnet/flashplayer/articles/what-is-agal.html
Again, sorry for the inconvenience.

1.3 is more slow then 1.2

Hi
I found the 1.3 more slow then the 1.2 , i mean the sliders are slow to move in the develop module using the zoom ratio Fit to screen
the 1.2 is blazing fast , the 1.3 is slow
I run it on xp , p4 3.6 ,4gb of ram , and 4 sata2 in raid
I did notice that the sliders are slow , sticky not smooth only in the fit to screen zoom ratio in the other ratios it's fast
I played in the catalog setting , with different setting and i tried to render 1:1
, update ati drivers ,i have a x800 pic express with 512 mb of ram
this version 1.3 has for me the same problem of the 1.0
my spec
Giovanni P4 3.6 ,4gb ram ,4 hds sata2 seagate 320gb, xp pro 2 , ati x800 pci-express 512mb , photoshop cs3 ,lightroom 1.2

I want to add my voice to the "1.3 is slower than 1.2 list"
We work with both PC's and Macs, and we are both sitting here shaking our heads as to the slowness... almost unusable when trying to sort photos.
The slowness is very dramatic AFTER you have applied a few edits to a photo. So if you have cropped, adjusted exposure, etc, to a bunch of photos, and then you want to go through all the adjusted photos to further narrow them down, the "rendering larger version" message goes on for a long time between each photo. While that happens, the photo is very blurry.
Lightroom seems to be an acceptable option only for people that are working with a few dozen photos at a time. In my case the collection that I have adjusted and am trying to narrow down is about 330 images.
Yes, I have rendered the photos both large and 1:1. From RAW files.
I am re-rendering now (over 1 hour so far and still waiting) the large versions after they have been adjusted.
If forcing a re-render fixes the problem, that means that Lightroom is not storing an adjusted preview whenever it leaves a photo, causing the preview to be recalculated every time it gets revisited from then after. It seems that crop and rotate can make things really bad.
(And before you bother Lee Jay... we know that Lightroom works perfectly peachy-keen for you all the time)

The response time of wifi in ios 5.0 is now much slower then in iOS 4.2

The response time of wifi in ios 5.0 is now much slower then in iOS 4.2.
It takes sometimes 30 sec till 1 minute that something happend.
I have an iPad 1 64gb with 3G..

Looks as if it is to do with your iPhone, if it can't find any Wi-Fi networks and they are turned on and set to discoverable, even after restarting the router it's still unable to find it my recommendation is to do a restore through iTunes, the update may not have installed properly, I have an iPhone 4 16GB (Black) running iOS 5.0.1 and it finds my Wi-Fi networks and log's onto them no problem, so clearly the software works, just seems that your iPhone is having a bad time
You've done everything else I'd reccommend, normal re-boot, soft reset, reset network settings.
Think it's time to do a full back up in iTunes and do the restore, then see if that resolves the issue, be sure to let us know how it goes if you do decide to do this.

My Ipod was acting slow then i turned it off it wouldnt turn back on then i tried some restore thing it turned on deleted everything and upgraded software then i tried restoreing it again no my i pod dosnt turn on and is read as usb unknown device?

My ipod was acting slow then i turned it off it wouldnt turn back on then i did a upgrade and restore deleted all my things now it wont turn on???
del

Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try another cable
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

Video slower then the sound..

I bought a movie and it worked fine until I was prompted to upgrade Itunes. Now the video is slower then the sound. If I delete the movie can I re-download it? I have seen other people post something similar and no one is getting a answer... If I can't get a fix to this I will not get another movie on Itunes.

Two questions, What IPOD Software version are you
running and what software program was used to convert
the videos with?
First off mainly it is what firmware you are running, not what you convert the videos with, Barbara please get your stuff straight, I don't even own an video Ipod and I know it has nothing to do with conversion, jeeze.

Why to Use EJB rather then Direct Connection To Oracle Thru webDynpro?

Hi
Experts,
I want to know that why to use EJB to connect to oracle rather then direct connection via WebDynpro.
Please Give Me References to how to connect to oracle with EJB or WebDynpro.I want to tell you that i know JDBC,JAVA and basic web Dynpro.
Please Reply Me Dear Friends...ASAP.

EJB are better for a project beacuse the application is scalable, have less maintainence and have better performance.
Have you gone throght these:
Connect Oracle 9.2 DB to Web AS 6.40
web dynpro - database connection
web Dynpro application connecting to oracle
