Many Queries slowing down performance?

Hi,
Our query response time is very bad, sometimes 30min to execute a query!
I noticed that there have been created a few hundred queries on the respective MultiCube.
Is the bad performance linked to the number of queries?
What advise can you give to speed up performance?
Many thanks!!
Sabine

  • Does loading too many classes into jvm slow down performance?

    hi all,
    does loading too many classes into jvm will slow down performance. Our application is CPU bound, if we use any framework we need to load all the classes related to that framework in JVM. Does this have any effect on the performance of the JVM.
    thanks and regards,
    akmal

    does loading many classes into jvm slow down performance.It will increase the time it takes for the JVM to load your application.
    Our application is CPU boundThe time it takes the JVM to load your application is not likely to be an issue for you then.

  • Does too many apps slow down iphone's performance?

    does too many apps slow down iphone's performance?

    31 apps is nothing. I have 130 apps XD. Then again, I'm using an iPhone 4S which has more RAM compared to the 3GS. RAM is everything when it comes to speed. To use the app switcher, press the home button twice quickly and a list of your recently opened apps will appear. Then hold down on any app and all the apps will go to wiggle mode (like they do when you're deleting apps. Now, simply tap on the red icon that appears at the top left corner of any app you don't want running in the background. This will free up RAM and should make your phone faster.

  • Can too many Photos slow down a Mac Pro?

    Hi, I have atleast 100,000 photos on my pc, would this many photos slow down a 2.66GHz quad core mac pro with 6 gigs of memory? thanks

    I have 60,000. I use non-boot drive of course for data. Some people have huge music and video libraries of 2TB spanning 2-3 drives on stripped RAIDs.
    Mac Pro and OS X really likes RAM, and the base for DDR3 8-core is to have 6 DIMMs and I'd go with 6 x 2GB, either Apple or 3rd party RAM, then add 3 x 640GB drives (WD Black Caviar). Stripe two, even if you partition it as 400GB each. http://www.barefeats.com/nehal04.html
    And keep the boot drive to OS and applications primarily.

  • Functions slowing down performance question

    Hey there.
    I've got a query that really slogs. This query calls quite a few functions and there's no question that some of the work that needs to be done, simply takes time.
    However, someone has adamantly told me that using functions slow down the query compared to the same code in the base SQL.
    I find this hard to believe that the exact same code - whether well written or not - would be much faster in the base view than having a view call the functions.
    Is this correct that functions kill performance?
    Thanks for any advice.
    Russ

    There is the performance impact of context switching between SQL and PL/SQL engines. Pure SQL is always faster.
    SQL> create or replace function f (n number) return number as
      2  begin
      3    return n + 1;
      4  end;
      5  /
    Function created.
    SQL> set timing on
    SQL> select sum(f(level)) from dual
      2  connect by level <= 1000000;
    SUM(F(LEVEL))
       5.0000E+11
    Elapsed: 00:00:07.06
    SQL> select sum(level + 1) from dual
      2  connect by level <= 1000000;
    SUM(LEVEL+1)
      5.0000E+11
    Elapsed: 00:00:01.09

  • Infopath dataconnection slow down performance

    Currently I am working on one project, and I created InfoPath form , that form has 20 to 30 fields.
    Out of that 15 are dropdowns, and for those 15 dropdowns I have created secondary connections(11)
    Due to so much of these connection My form taking much time to load,and same time there will be much more users will load forms, so it is creating much performance issue.
    is there any way that my connections will be cached for all users or something like that .? or how to improve performance in this case ?
    Please mark answer , if you think answer is helpful or correct.

    Data queries are ALWAYS performed live... depending on the query, they may be performed during form load, or on demand (which may help if you are able to provide filters during lookup)... but no, there is no result caching.

  • Too many albums slows down iTunes?

    I've never used iTunes to organize my massive music library, but I want to give it a try.
    I don't think in terms of songs.  I think in terms of albums - ripped CDs.  I have over 3,500 physical CDs and FLACs I'm converting to ALAC.
    I read some very old forum posts that discussed iTunes bogging down, sometimes hanging or crashing, because someone had "too large" a library.   But those comments I read were several years old, obviously discussing older versions of iTunes.
    Assuming that lossy compression is completely out of the question, is a person going to notice iTunes 11.1 responding slowly or hanging with that many lossless albums in his library?  A drag to use?
    Without resorting to multiple libraries, how many ALAC albums is "too many" for iTunes?

    I think a LARGE PART of what you're dealing with is format...
    I have 41,742 songs (3212 albums) and 673 audiobooks in my iTunes library with album art for ALL of it.
    It ONLY lags when adding new tracks, and even that's just for a second or two at most.
    BUT...
    My collection is MP3 (192kpbs maximum) and M4B (128kbps maximum). EVERYTHING comes to 267Gb.
    As FLAC or ALAC, you're looking at a substantially larger library that's going to be slower to update...
    Updating a 23mb ALAC track's ID3 tags... takes longer than a 4mb MP3.
    Updating artwork for an album of ALAC tracks... takes longer than an album of MP3 tracks.
    Renaming an album of ALAC tracks...  and so on.
    Not being a music professional I don't NEED to have lossless music. I listen to most of my stuff through earbuds while riding. Too much outside noise to really appreciate the nuances of a studio quality rendition of Beethoven's 9th.
    If you DO need that quality, the lag is a trade off.

  • Do apps running in the background drain battery, slow down performance, or use cellular data?

    I have heard that if you don't kill the apps running in the background, they will drain your battery, slow your other apps down, and could be using your data without any warning.  I've looked all over the place for a definitive answer to this, but different people and websites provide conflicting responses and I haven't found any useful information regarding this issue directly from Apple.  If anyone knows whether or not having apps constantly running in the background is harmful in anyway (and has a credible resource to back up their claim) let me know and provide a link to the answer if possible.

    What do you mean 'running in the background'? Something that is 'running' will definitely use battery, nothing runs on air or whatever. If an app uses data while it's 'running' then it will use data. Why do you need a link, it's common sense isn't it? Slow the phone down? That I can't say definitively, but it stands to reason that it will. 

  • Leopard slowed down performance on my G5

    Not sure how to fix this, need some basic advice. I just loaded Leopard into my Power PC G5 and it's moving through applications, etc like molasses in January. Do I need to upgrade anything?

    Hi! A couple of things may be slowing it down. One is spotlight which may be indexing drives and also Time Machine which takes a few hours for the initial backup. There could also be some temp files created that haven't cleared themselves. I usually recommend letting it run for at least 24 hours without sleeping to give it time to catch its breath. You could also have some apps that aren't Leopard compliant but those should have been checked for compatibility before loading Leopard. Usually though incompatible apps produce worse results than just a general slowdown. Tom

  • Will having too many apps slow down ur iphone4

    just like the topic says, will it slow the phone down? or drain the battery faster?

    Having apps shouldn't affect anything.
    Using apps will obviously use battery, as will using the phone, the ipod,etc.

  • Bootcamp slowing down performance

    Hi all,
    I installed Windows 7 ultimate using bootcamp the other night, and I've been finding that on the mac side of things, things have gotten a bit slow. Loading applications, including native ones such as system preferences take up to 10-20 seconds for it to open up. I've reset the SMC, PRAM, fixed disk permissions while seeing not a huge amount of improvement.
    Does anyone have any experience with this? I'm running 10.6.8 and my MBP is a early 2011 model.

    Windows and OSx are in separate partitions and therefore do not affect each other when running. That said, there have been other posts in the Boot Camp forum from people who say they experience the same symptoms as you.
    My suspicion is that you are running short on hard drive space since creating the Boot Camp partition. How much free space do you have in your OSx partition?

  • Does re-installing system slow down the HD?

    Hi
    My MBP came back from repair with a new HD and OS 10.5 already installed. For various reasons I might want to wipe it and re-install the system software. But does this process of re-installing the system leave any 'debris' on the drive which might slow down performance in the long run? If so I may leave it, but it's a question I've always wondered about - when you re-install does the drive go back to being 'like new' again or is there a gradual accumulation of code which just adds more clutter?
    Thanks for any help

    If the OS or an app or whatever needs 10GB (for example) of free space, what does it matter if it's 10GB out of 100GB or 10GB out of 1TB?
    I don't think it matters.
    I thought that's what MacRS4 is saying
    I did not understand it to be. The assertion was:
    The 85% corruption thing fassumes a relationship of the largest file types to the size of the physical drive.
    It does not. It assumes that the directory expansion varies with the total amount of data that needs to be stored. The 85% refers to the smallest amount of contiguous disk capacity needed to permit the file system to lay down new pieces of the Extents Overflow file. That does not have to do with the size of any individual file but with the total amount of data that needs to be accommodated in the file system/directory.
    this question seems to asd for just the opposite, a rationale as to why a percentage would be needed, not a set amount of space.
    My intention was to suggest there was a relationship (read percentage) between the total amount of data on the drive and the size of the filesystem. On a 100 GB HDD the filesystem will be smaller as the amount of data stored occupies a smaller amount of disk capacity. On a 1 Terabyte HDD 85% of total used capacity requires a corresponding size of directory. As I understand it the size of the directory varies in direct relationship with the amount of data stored on the drive and not to the total capacity of the HDD. The Micromat study (sorry, I have lost the link for that reference) found that the optimal capacity was 85% to avoid directory corruption.
    As I noted in earlier posts, the equation may have changed with the advent of larger capacity drives, but I am not aware of documentation to that effect. I should also add that I am not by any means an expert. However, I am not willing to test to see how crowded my HDD has to be before I encounter an unrecoverable directory.
    My asking for support for statements made is not by way of debate. I earnestly seek to learn more about this and other subjects from those who have information I do not, myself, have.

  • I'm about to buy a 27" i-Mac. I would like to connect my 30" Cinema Display to it as a second monitor. What will I need to do that? Will this slow down the overal performance?

    I'm about to buy a 27" i-Mac. I would like to connect my 30" Cinema Display to it as a second monitor. What will I need to do that? Will this slow down the overall performance?

    The new iMacs do not come with a MiniDisplayPort, they have Thunderbolt, so unless you are talking about purchasing one of the previous generation iMacs such as this refurbished model in the online Apple store, it won't work. And yes, if you are going to get the full range of video resolutions you will need the Dual-Link version.
    For details see the store's web page on the Dual-Link display adapter.

  • Performance slows down when moving from stage to test schema within same instance with same database table and objects

    We have created a stage schema and tested application which is working fine when we are moving it to another schema for further testing ( This schema is created using same scripts which were used to create objects in staging schema) the performanc of application (Developed in .NET) slows down drastically
    Some of the store procedures we have checked at Databse/SQLdeveloper level are giving almost same performance but at Application level there is lot of difference
