Query slows down after second run for Index Organised Tables
We are trying to optimise our application which supports MSSQL to run with Oracle 9i for one of our customers.
We have created one database with normal tables and PK constraints/indexes and turned caching on for the tables, this seems to work well but no way as fast as MSSQL on similar hardware. The first run of query was slower but as the caching became more effective the query times came down.
So we investigated turning the tables into Index Organised Tables. We ran analyze on the new indexed tables and the response time of one of our more complex queries became akin to MSSQL. We ran the same query 5 seconds later and it took about 3 times longer to return the same data. Subsequent runs produced the same result.
We have run the same query on both styles of tables and also run showplans on the two queries, the regular table returns a cost of 190 and the IOT 340. This would point to the fact that we should use the regular tables for our queries but why did the IOT set return much faster for the first run after the analyze then slow down as if the stats were missing, but the execution plan remain the same.
Any help would be appreiciated.

could be a lot of reasons:
1. Is Oracle the only process that runs on this server? Could it be any other process (i.e. MSSQL) that took the the resources during the secodn run?
2. Is this the only query that was running during your tests? Could there be another query that put the load on the database when you were running the second test?
3. The autotrace statistics and explain plan would be useful for first and second run
(how to use autotrace:
http://download-west.oracle.com/docs/cd/B10501_01/server.920/a96533/autotrac.htm#1018
4. If you run the same process again several times - how does the response time change?

Query slows down after upgrade
Hi,
After upgrade from oracle 10 to oracle 11 a simple query is slowing down alot.
Same amount of records, same table only the execution cost time is increased
Can someone give me some feedback over this problem?
Can I check some things to look into the problem?
Thx in advance.

Is it just one query or all queries are behaving strangely? If it's just one query, do a trace and see where it's slowing down.
In the meanwhile, you can also modify the optimizer_features_enable parameter at session level and check the explain plan.
Alter session set optimizer_features_enable='10.2.0.5';
Now test the query.
By the way, if you are just worried about the COST factor, you can just ignore it. COST by itself has no real meaning. You will only have to look at the response time.

Adobe slowed down after running fine on a Mac Book Pro Photoshop settings have been reset
adobe slowed down after running fine on a Mac Book Pro. Adobe Settings have been Reset
Hello Gener7,
I did try everything on the FAQ page (all steps) I also did them a few more times with "Adobe help" walking me through 2 more times. I just don't get it, I have been on with Adobe on some days up to 5 hours at a time for over a month now. I think it must be something with the installation disc but they say no, no, switchboard is just not working on my OS X 10.9.4. I even took the computer into the apple store here and had them look it over, reinstall everything and they say it's the Adobe software.
Thank you very much for your help, it's nice to know someone is reading this :-) I do work around this by saving the files and reopening them in the next program I need but everyone in class is always waiting on me, (it sucks) and I just think it should work. Hope you have a good day and I will put an update on here if this is ever figured out.
Thanks one more time :-) -
Since the update to Yosemite the MacBook has slowed down appreciably. Safari for example takes upwards of 30 seconds to load. How can I speed things up?
Hi ..
Not enough free storage space can slow your Mac down.
Click your Apple menu icon top left in your screen. From the drop down menu click About This Mac > More Info > Storage. Make sure there's at least 15% free disk space.
Freeing space on your Mac OS X startup disk
OS X Tips Where did my Disk Space go?
Check to see if the startup disk needs repairing.
Launch Disk Utility located in HD > Applications > Utillities
Select the startup disk on the left then select the First Aid tab.
Click: Verify Disk (not Verify Disk Permissions)
If Disk Utility reports errors, restart your Mac while holding down the Command + R keys. From there you should be able to access the built in utilities in OS X Recovery to repair the startup disk.
Make sure to back up all important data first before using OS X Recovery.
Anti virus software, as well as third party Mac cleaning utilities such as MacKeeper and CleanMyMac can also slow your Mac down.
For Safari.
Open a Finder window. From the Finder menu bar click Go > Go to Folder
Type or copy paste the following
~/Library/Caches/com.apple.Safari/Cache.db
Click Go then move the Cache.db file to the Trash.
Relaunch Safari to test. if that doesn't help, troubleshoot Safari extensions.
From the Safari menu bar click Safari > Preferences then select the Extensions tab. Turn that OFF, quit and relaunch Safari to test.
If that helped, turn one extension on then quit and relaunch Safari to test until you find the incompatible extension then click uninstall. -
Query slow down when added a where clause
I have a procedure that has performance issue, so I copy some of the query and run in the sql plus and try to spot which join cause the problem, but I get a result which I can figuer out why. I have a query which like below:
Select Count(a.ID) From TableA a
-- INNER JOIN other tables
WHERE a.TypeID = 2;
TableA has 140000 records, when the where clause is not added, the count return quite quick, but if I add the where clause, then the query slow down and seems never return so I have to kill my SQL Plus session. TableA has index on TypeID and TypeID is a number type. When TablA has 3000 records, the procedure return very quick, but it slow down and hang there when the TableA contains 140000 records. Any idea why this will slow down the query?
Also, the TypeID is a foreign key to another table (TableAType), so the query above can written as :
Select Count(a.ID) From TableA a
-- INNER JOIN other tables
INNER JOIN TableAType atype ON a.TypeID = atype.ID
WHERE atype.Name = 'typename';
TableAType table is a small table only contains less than 100 records, in this case, would the second query be more efficient to the first query?
Any suggestions are welcome, thanks in advance...
Message was edited by:
user500168TableA now has 230000 records and 28000 of them has the TypeID 2.
I haven't use the hint yet but thank you for your reply which let me to to run a query to check how many records in TableA has TypeID 2. When I doing this, it seems pretty fast. So I begin with the select count for TableA only and gradually add table to join and seems the query is pretty fast as long as TableA is the fist table to select from.
Before in my query TableA is the second table to join from, there is another table (which is large as well but not as large as TableA) before TableA. So I think this is why it runs slow before. I am not at work yesterday so the query given in my post is based on my roughly memory and I forget to mention another table is joined before TableA, really sorry about that.
I think I learn a lesson here, the largest table need to be in the begining of the select statement...
Thank you very much everyone. -
Lightroom workflow slows down after modifying an image
Hi fellow users,
Lightroom 4.3 runs smoothly if I work on unmodified images.
However, if I apply modifications on an image, retouching it afterwards becomes much slower, even if I render a preview AFTER I made modifications on the image.
I tell you an example: I import a raw file to the program and I render it`s preview. Then I retouch the image - it works very fast, no waiting time, no Loading overlay.
Where the problem starts: I import a raw file, I apply some modifications on it (for example a preset), then I render it`s preview - then I want to do more modifications on the image, which becomes very slow.
I was monitoring the cpu usage of the computer. In the first case, the cpu usage during modifying the image is normal.
In the second case, it goes up to 100%.
It seems that applying modifications on an image makes working on it slow, no matter if you have the most up-to-date preview or not.
Anyone knows if it is normal or not?
Is there any solution to this?
Thanks,
Tamas
My configuration:
Windows 7 64 bit (up to date)
Lightroom 4.3 64 bit
Fast PC
lightroom settings:
camera raw cache: 20gb
video cache: 10gbFirst of all, you can forget about the preview rendering, that's irrelevant. Previews are only used by the Library module, not the Develop module. In Develop, it's handled by the ACR cache.
Now, as for slowing down after initial adjustments, that's a variable I haven't looked out for. But it could well be correct (it would explain some weird results I got across two machines recently).
In general, Lightroom 4 performs well below expected standards on some systems, while others fly along, and it seems nobody can explain why. Long story, do a search on this forum and you'll come up with several lengthy threads. The problem is that there are so many variables in this that it's almost impossible to even define what "slow" means. And now you've added another (interesting) one... -
Server slows down after a while
Hi all,
I've a problem with a linux machine which slows down after running for
some days. It usually handles about 100 request per second and after a
while it goes down to about 5 requests per second. I'm running WL6.1Sp1
on Linux with JDK1.3.1 and "-hotspot -ms512m -mx512m". I'm wondering if
this is related to some problem in my code or maybe rather is a database
issue. I took a thread dump, and the server looks idle. Does anyone see
something unusual in this dump? Does it indicate anything else than a
nearly totally idle server?
Thanks for your input!
Daniel

Hi all,
I've a problem with a linux machine which slows down after running for

on Linux with JDK1.3.1 and "-hotspot -ms512m -mx512m". I'm wondering
if
this is related to some problem in my code or maybe rather is a database
issue. I took a thread dump, and the server looks idle. Does anyone see
something unusual in this dump? Does it indicate anything else than a
nearly totally idle server?
Thanks for your input!

System Slow-Down After Printing
I recently installed Mountain Lion. Over the last couple of weeks I have noticed a significant operating system (10.8.2) slow down after printing with my Epson R3000 printer. This happens after every printing session. When I say slow-down I mean significant delays and dreading "beachballs" when opening applications, selecting menu items or anything else I should choose to do. I'm left with re-starting the computer to get going normally again.After re-atarting I have gone to "verify permissions" and I get approx "5" pages of permission errors, all associated with the printer library in some fashion or another. I then repair all those permissions and re-start my MacPro. The operating system then works as normal and I can use the computer with no problems (until I start printing again). I mainly use the computer for photo editing with Adobe Photoshop CS6, Adobe Lightroom 4 and Aperture 3.2.
I did not have this problem before upgrading to Mountain Lion (and then to 10.8.2). I did not get "significant" permission errors before upgrading. Since all printer drivers for this printer are handled now by Apple via the "new" Software Update process I can't even re-download the Epson printer driver and start over. I'm completely at a loss as to what, associated with the printer function, is causing these "significant" permission errors and subsequent operating system slow down. My printer is almost brand new and was working flawlessly before Mountain Lion. Let me be clear though, I can print fine. My problem is the system slow down after using the print function which I am only guessing has something to do with the "5" pages of permission errors after printting photos (with CS6/Lightroom/Aperture).
Incidently, I am not in any way a computer expert. Verifying and repairing permissions is about all I know how to do that's why I need help. I also just thought I would try the forums first before going to technical support to see what people thought about this.
Again, I repair the permission errors, re-start my system and all is fine. Any further suggestions would be deeply appreciated.When you see a beachball cursor or the slowness is especially bad, note the exact time: hour, minute, second.

Slow down after installing Lion OS
My Macbook pro later than 2009 model slowed down after installing the new OS Lion
any suggestions to speed it upFirst suggestion ,there have been a number of identical user questions like yours, in the Lion Community. If you want to talk to other MacBook Pro owners, try the forum they have.
http://www.apple.com/support/macbookpro
What you do not need is some gizmo to "speed up" or clean caches etc.
Maybe you need to make more room on your hard drive, or add more RAM.
For now, hold down Command-R and run Disk Utility to check the health of your system drive (Lion Recovery Mode)

Compleat system slow down after current updates
Has anyone learned why we all seem to have a compleat system slow down after the current set of updates? Everything works, but is VERY slow to respond. Even iTunes 7.1.1 plays video choppy now. Audio track plays fine however. Odd.
-Apple //GSFirst of all, try repairing your permissions with Applications> Utilities> Disk Utility. Select the hard drive you're running off of and then click the Repair Permissions button.
If that doesn't work I'd do an archive and install:
http://docs.info.apple.com/article.html?artnum=107120
Then run the combo update(s) instead of the consecutive ones. That seems to be working for a lot of people, but it will probably take a while. -
System slow down after upgrade to 10.10.2
Still have a slow down after updating to 10.10.2
Tried everything I can think of.
Get spinning color wheel for a long time when opening even small files. Scrolling through folders, cursor hangs for a moment. opening and saving takes much longer.
Used HD repair and repaired permissions and diagnosed HD. No problems.
Looking at Activity Monitor, I don't see anything that stand out-

Why do my loops slow down after many iterations
My Vi seems to freeze up or slow down after several iterations of the loop. This is an Analog Input Capture VI.
Attachments:
Final_Main_VI_with_working_amp.vi 456 KBFirst of all, thank you for your contribution. You are right to say that I have no need in changing the AI Config every time that the loop runs. But as this is supposed to be a soft-scope, I need to be able to update the parameters associated with AI Start while the loop is running (e.g. trigger level).
I have tried to move the AI Config subVI out of both loops but the error as a result is: "No transfer in progress for the specified source."
I also need a sampling rate of exactly 96kHz. I realize that the laptop clock cannot attain this value. Do you know how I could get exactly 96kHz.

AME CS4 Batch - Slow Down After First File
I've been using AME to batch timelines from various different Premiere Pro projects. Problem is the first one in the batch will take the normal amount of time around 2 hours. Then everyone in the batch after that takes 5 hours.
If I stop the encode once it gets to the second file and slows. And then restart the program and put that one as first it renders in a fraction of the time....
Why does AME drastically slow down after the first file in the queue?Where do you close the ResultSet?
Where do you close the Statement?
Presumably you only create one connection for all users or you close it somewhere. -
Why does my data logging program slow down after a while?
A data logging program created with Labview 5.1. Slows down after a few weeks and creates files in the Temp. directory.Computer is Siemens Scenic pro 124 MB ram and AT-MIO-16XE50 Data acquisition board. Also using Solartron Dig. probes and Fieldpoint units.
Any chance that you are using Win 95/88/ME? Those OS's have well documented
memory leaks which will consume all your available memory if an application
is run long enough. Also there are some issues of memory management within
LabView in the allocation of memory.
The solution to the first is to switch to WinNT/2K. The second will be much
more difficult.

System slow down after lion update 8/18/11
Has anyone else had a problem with their system slowing down after downloading the system update for Lion on 8/18? My system is not nearly as responsive and is only about two weeks old and have not installed any software other than Microsoft Office 2011 when I bought the machine. Any ideas?
Ok my system is booting and shutting down faster now.. This method worked for me:
First, I repaired the permissions:
1) Open up Disk Utility
2) Select your hard drive
3) Now select Repair Disk Permissions.
