Dashboard Performance - Very Very Very Slow

Hi everyone, I would like to take some suggestions regarding the performance of Dashboard Pages.
This is our first OBI project and were running into several performance issues. So far everyone in the team focused mostly on the functionality of the dashboard pages and we were happy to see it work as expected.
But the biggest problem right now is the performance.
When we log into the OBI, it takes at least 10 minutes to log in. We see this message... "Logging in please wait"
Once we log in and click on the Dashboard, it takes another 5 to 10 minutes to show the first page.
The pages we have in Dashboard have more than 60 answers requests (Guided Navigation) and about half a dozen Prompts (Constrained). Call it as a poor architecture or design plan, but this is what we wanted from a functionality and business stand point.
Are there any specific areas on the Physical Server that we can focus to upgrate stuff like RAM, CPU usage, etc........ to improve the overall performance of the Dashboard?
Everytime we report the poor performance to our Windows Team, we get the same answer that the CPU usage from their eyes is very normal by the OBI stuff. They inturn asking us what are the log files or areas they need to check to grant more CPU usage for OBI.
Any help is greatly appreciated.
Thanks
Sai

Hi David,
Here are my answers for your questions earlier:
1. How many users are running this dashboard at the same time?
3-5 right now. But once this stuff is completly done, it will be accessed by at least 1000 external clients.
2. What is the database?
Oracle 10.2.0.4.0
3. Have you changed any config parameters?
All defaults except turned on “Execute queries asynchronously” yesterday
4. The defaults are rarely okay for some of them. You need to look at the connection pool(s) settings. How many max connections?
10
5. Is pool sharing on?
“Connection pooling enabled”
6. Is multithreaded on?
Yes
Also, David regarding
"Users having to wait at login often means that connections or threads are gated on the OBI server. You may need to bump up SERVER_THREAD_RANGE (try 500_500) and DB_SERVER_THREAD"
Where do we do this. I mean, where can i find this attributes ????
Thanks
Sai

Is anyone facing the similar problem of visible lag while opening app with 3G data on? It seems apple has made 5s slow to improve iphone 4 performance.5s was very smooth on 7.0.6 even with 3G data on. Is this a bug? Is apple going to fix this soon?

I have same Problem. I tried all options - Reset All Settings, Erase Content & reset all settings, Upgrated to IOS8.1, Restore using iTune. But problem persists.
When I turn Cellular Data or Wifi ON, then there is a lag while opening the Apps. But If I turn Data/Wifi off, phone becomes super fast. I have checked with my friends. They are not facing this issue. Not sure if Apple know this.

Cover flow very sticky and slow with garbled images

The images in my cover flow area are gibberish, literally random lines and colors and cover flow itself is very sticky and slow. Oddly, there are on occasion covers that are normal. Does anybody know what this is or is anybody having this issue? It was this way with 7.6 and it's the same way with 7.6.1, I was hoping it would get corrected.

Comment about my previous comment. It's not just slightly slow, it's incredibly slow as in press the slidebar down arrow and wait a couple seconds for 1 increment of movement slow. The only time is returns to a normal speed is when I go to a screen without cover flow. For example, when I click the 'all movies' link in the iTunes store. I had this problem with 7.6 and it still exists with 7.6.1.

After closing Firefox to use IE8 or any other program (like InterVideo to watch a DVD), everything is very choppy and slow. I have to go into Taskbar, Processes, and close firefox.exe manually (which is using up all the memory/CPU and should have closed before). Then, and only then, does everything behave normally. What is going on and what am I doing wrong or missing??
== This happened ==
Every time Firefox opened
== about a couple months ago and happens every time I close Firefox.

'''Kill Application'''
In Task Manager, does firefox.exe show in the '''Processes''' tab?

'''Causes and solutions for Firefox hanging at exit:'''
'''[[Firefox hangs]]'''
'''[http://kb.mozillazine.org/Firefox_hangs#Hang_at_exit Firefox hangs at exit (Mozillazine article)]'''
'''[[Firefox is already running but is not responding]]'''
'''Safe Mode'''
You may need to use '''[[Safe Mode]]''' (click on "Safe Mode" and read) to localize the problem. Firefox SafeMode is a diagnostic mode that disables extensions and some other features of Firefox. If you are using a theme, switch to the DEFAULT theme: Tools > Add-ons > Themes before starting Safe Mode. When entering Safe Mode, do not check any items on the entry window, just click "Continue in Safe Mode". Test to see if the problem you are experiencing is corrected.
See:
'''[[Troubleshooting extensions and themes]]'''
'''[[Troubleshooting plugins]]'''
'''[[Basic Troubleshooting]]'''
If the problem does not occur in Safe-mode then disable all of your extensions and then try to find which is causing it by enabling one at a time until the problem reappears. You have to close and restart Firefox after each change via File > Restart Firefox (on Mac: Firefox > Quit). You can use "Disable all add-ons" on the Safe mode start window.

Why is my new iPad mini with retina very, very jerky and slow?

Hi,
Does anyone know what I can do about my new iPad being very, very jerky and slow?
FACT - The multitouch screen is unresponsive and I have to press and press and press to select what I want before it reacts.
It's an iPad mini with retina, so it's got the new chipset which runs really, really fast.
FACT - What happens is:
I start up pages and it freezes completely for quite a while before allowing me access to my documents.
I go to settings and it freezes up totally for quite a while before allowing me access to my settings.
Is there a cure? I get similar problems on my acompanying really, really fast iPhone 5s.
PS
Plenty of memory left so no problems there - only about half used and they're both 32gb.
...and my beloved iPad2 never used to do this either.

If You Think iOS 7 Feels Slow Here’s How to Speed It Up
http://osxdaily.com/2013/09/23/ios-7-slow-speed-it-up/
You may have many apps open which can possibly cause the slowdown and possibly the loss of wifi. In iOS 4-6 double tap your Home button & at the bottom of the screen you will see the icons of all open apps. Close those you are not using by pressing on an icon until all icons wiggle - then tap the minus sign. For iOS 7 users, there’s an easy way to see which apps are open in order to close them. By double-tapping the home button on your iPhone or iPad, the new multitasking feature in iOS 7 shows full page previews of all your open apps. Simply scroll horizontally to see all your apps, and close the apps with a simple flick towards the top of the screen.
 Cheers, Tom

Why performance of Illustrator CS6 slower than Illustrator CS5.5?

Ex: Process get text of TextFrame has 657 characters:
Dim t1 As String
Dim t2 As String
t1 = DateTime.Now.Minute & " " & DateTime.Now.Second & " " & DateTime.Now.Millisecond
Dim text As String
For iChar = 1 To iCharNum
      oChar = oContents.Characters(iChar)
      Dim str As String
      str = oChar.contents.ToString
      text = text & str
Next
t2 = DateTime.Now.Minute & " " & DateTime.Now.Second & " " & DateTime.Now.Millisecond
Result:
Time of CS5.5: 0s 487
                         t1= 38 43 71

Paint performance with JScrollPane very slow in jdk 1.4?

I got a simple program that overrides paintComponent on a JPanel. Then draws lots of lines, rectangles and some strings. The panel is then added to a scrollpane.
The scrolling is very smooth in java 1.3.1, but very slow in 1.4.2
the paintComponent takes between 16ms and 30ms with java 1.3.1 but 70-200ms with java 1.4.2.
I tried turning of antialising etc.. but no help. Whats the "improvement" they made in jdk 1.4?

Ok I made a simple example, which draws around 5000 elements.
Sourcecode is here: http://www.mcmadsen.dk/files/ScrollPaneTest.java
I did several testruns on java 1.4.2 and java 1.3.1, heres the "avarage" result:
Java 1.4.2:
Current: 140ms High: 203ms Avg: 144ms Low: 125ms
Java 1.3.1:
Current: 62ms High: 219ms Avg: 68ms Low: 47ms
The paintComponent() looks like this:
public void paintComponent(Graphics g)
super.paintComponent(g);
long offset=System.currentTimeMillis();
PaintElement paintElementTmp;
for(int i=0;i<paintElements.size();i++)
paintElementTmp=(PaintElement)paintElements.elementAt(i);
g.setColor(paintElementTmp.getBackground());
g.fillRect(paintElementTmp.getX(),paintElementTmp.getY(),paintElementTmp.getWidth(),paintElementTmp.getHeight());
g.setColor(paintElementTmp.getForeground());
g.drawString(paintElementTmp.getText(),paintElementTmp.getX(),paintElementTmp.getY());
long done=System.currentTimeMillis();
long current=done-offset;
sum+=current;
if(current>high)high=current;
if(low>current)low=current;
count++;
System.out.println("Current: "+current+"ms High: "+high+"ms Avg: "+(sum/count)+"ms Low: "+low+"ms");
I tried all the renderinghints, but no difference (from the default settings). Also the scrolling is very slow and stops all the time in java 1.4.
Any ideas on how to get java 1.4 to perform as java 1.3.1?
Thanks

Very large collection, slow iTunes

I have a massive iTunes library, about 500 GB and 95,000 songs. I have been collecting music for almost 40 years and have ripped my entire CD collection and about 1,000 of my LP's so far. But iTunes is very slow with a large collection like this. Browsing by any of the cover art options is painfully slow. Does anyone have tips on how to speed things up? It wiould be appreciated. All of my music is in AAC format.
iMac G5 20 1.8 ghz Mac OS X (10.4)

I'm desperately trying to solve this problem as well. Here's my experience:
- almost 60,000 songs/300+GB
- Dual 2.0 G5 w/ 3.5 GB of RAM
- takes time to load library at application start-up (understandable and doesn't bother me).
- have run it on both internal and external firewire 400 drives with same problems.
- my main problem is getting the beachball when I <get info> to alter track info. There is some lag time when using the search box as well amongst a lot of other things. In general, the application just doesn't respond as fast as I would like and it seems to be the size of the library.
- I added 2GB of ram (up from 1.5) and that didn't help.
- My percentage of HD used does not seem to affect it.
My only other option (that I can think of) is to get a faster HD (or H Drives and stripe them) to try to increase access or seek times.
I found this bit of info though in another thread that I found very interesting...
"Re: Need Help with EXTREMELY Large Library!
Posted: Sep 7, 2006 7:21 AM in response to: Bill Ryan2
I don't know how much of the slowdown is iTunes managing its playlists, and how much is the operating system handling the iTunes Library (the single file containing the tag information).
I ran Sonar (http://www.matterform.com/macsoftware/filesecurity/) to watch file read/write activity while editing track tags. I saw a lot of iTunes Library temp and XML file writing.
My iTunes Library (for 160 Gb) of music is 53 Mb. But the Spinning Beachball corresponds to writing this file. Maybe a faster disk would help things."
This is my fear...that the fact that iTunes stores all that good info in one file (terrifying to me), that it can only handle so much.
Has anyone tried any sort of RAID array with fast HD's with large buffers? I'd love to know if this will help before I sink a bunch of cash into this setup. Multiple libraries are not an option for me...it's kind of like keeping half my records at another house.

FireFox 8 and 9 very very very ...slow

Hi,
My laptop is a Fujitsu Siemens Amilo.
Processor mobile AMD Sempron 2800+
RAM 512MB. Hard Drive 40 GB.
Windows XP SP3 Portuguese.
Standard Windows Firewall.
Antivirus Microsoft Security Essentials.
When I start the Firefox I have to wait almost 20 minutes to became ready.When I surf on the web also is very slow.
With firefox 5 and antivirus Avira I haven't this problem.
Also when I close my e-mail on the hotmail.com I get a message saying that my web browser is only safe in 2.4 out of 8.
Could give me some advice please.
I would like keep working with firefox.
Tanks,
Raul

Please try clearing cache and cookies and history. See [[Clear Recent History]] for an easy and quick way to do that. Also add-ons could be affecting the startup of firefox. Start firefox in[[Safe Mode]] and see if you are able to notice and differences.

My MacPro is running very bitty and slow.

I recently took up the offer of Apple's free Maverick upgrade. Oh dear....big mistake!
But since then, it runs incredibly slow and very bitty.
Also some applications are badly effected with the upgrade.
What can be done to eliminate this frustrating to work with situation please?
Also, how do I downgrade the OS, should this Maverick problem not be able to fix please?
