Gradual decrease in performance in allareas

Hi, I am running PS CS6 x64.  PC details are
Windows 8 professional 64bit
LGA2011 i7 3820
32GB RAM Quad Channel
NVidia GTX560TI
Several HDD's, scratch disk is a 2 disk stripe set
Master Suite CS6 and LR 4.3
All Adobe software is up to date
Running latest NVidia drivers
Up until recently Photoshop has been running OK.  Over the past week or so, when I have a file open, size and number of layers don't seem to make a difference, the performance gradually decreases to the point where using the pen tool to create 2 anchor point can take anywhere up to 20 seconds; this is just an example, this kind of slow down or lag happens with all tools. Shutting down Photoshop and restarting works, but after a few minutes it starts to slow down again.  Time taken to save files also increases once the slowdown starts
Actions taken so far...
I have reset all tool pre-sets
Deleted all Photoshop settings files
Purged history etc.
Confirmed all drivers and software up to date
Replicated the problem on small and large files with from 2 - 30 layers
Replicated the problem on existing PSD and PSB files as well as with new raw files.
Tried loading images from Lightroom and from directly within Photoshop
Changed performance settings (history & cache, gpu, memory etc.) and tried multiple configurations including enabling/disabling "Use Graphics Processor"
I can't think of anything else to try.  As mentioned, this is a fairly new problem that started about a week and half ago and is gradually getting worse.  I'm at the point now where I have to shut down Photoshop and restart it every 5 minutes.  I am a photographer, and when you have to do this for dozens of images, it becomes an untenable process.
Can anyone suggest some new tests or remedies?

I don't think you can get there from here (logging a ticket), unless one of the Adobe folks kindly goes out of their way to do so.  Generally speaking I think you'd need to call support.
This is the first I think I've heard of your specific issue here on the forum.  There have been occasional threads about sluggishness in general - just not progressively worse sluggishness.  What does Task Manager say?  Do you see the Photoshop.exe process chewing up CPU time?  What does Resource Monitor say?  Do you see a lot of (or progressively more) disk activity when Photoshop gets sluggish?
Regarding Norton, I'm not sure just disabling it is sufficient to test whether it's causing the problem.  You would have to remove it entirely (or refresh Windows).  I've not heard anything good about Norton software in a long time, and don't forget that Windows 8 comes with an anti-malware solution right out of the box.  That said, personally I use Avast! on all my systems.

  • Decreased Battery Performance when using SL. Apple states I am alone..

    This thread is mainly aimed at people that are using a mid 2009 unibody MacBook Pro 13" or upwards that came pre-installed with Leopard. Since upgrading to Snow leopard have you noticed a significant decrease in how long the battery lasts while using the machine in the same fashion?
    Am I alone? I first reported this issue to the Dutch customer service team back in October 2009 and since then have fought it all the way to make Apple admit that there is a problem with a minority of customers. To this day according to executive customer relations, I am the only person who has reported this issue to them. I find this hard to believe as there is a mass of information/threads/blogs etc on the internet with many people complaining about the same issue.
    The following is an email I sent to the [email protected] email as a last resort.
    Dear Steve,
    I am writing to you as a last resort hoping that my complaint will be dealt with professionally as I have actually given up all hope with the Apple customer service. I do not expect that you will personally read this letter but I just trust that someone will care and pass this to someone that will treat my complaint seriously as I really am losing all faith with Apple.
    I purchased a brand new Macbook Pro 13" mid 2009 model at the end of June 2009. Around 3 weeks after I purchased the machine I received a message from Apple stating that I was eligible for a copy of Snow Leopard as it was compatible with my machine and because I had just purchased a new Mac. I upgraded the Mac to Snow Leopard without any issues. It wasn't until a few weeks later that I noticed a massive reduction in battery performance. When I ran the machine on Leopard I would easily get the advertised 7 hour battery life while doing basic web browsing with all the battery settings set to the Mac default recommended settings. On Snow Leopard I would not get anything more than 4 hours completing the same tasks.
    I contacted Apple about this and was provided with the following reference number XXXXXXXXX I was basically told that I should monitor what I was doing etc and try using the screen on the lowest setting to see if this would improve the performance, it did not. I am a busy man and work in graphic design so unfortunately I put up with the battery issue until my Hard Drive decided to die in April. I contacted Apple again about this and was again provided with a reference number XXXXXXXXXX this time I was asked to do various steps to help fix the machine which did not work. Eventually I had the machine booked in for repair. When the machine was booked in for repair I also stated that I would like the battery issue addressed once and for all as I still only get around 4 hours charge. I was told this would be looked into. After 2 weeks of having no machine (and losing out on work) I received my Mac back with a new Hard drive installed as the old one was corrupted. I asked the Apple employee if my battery had been addressed and it had not. I refused to except my machine back as the battery issue was not resolved. After another 2 weeks of not having my Mac (more loss of work on my account) I received it back this time a new battery and motherboard had been installed.
    I returned to my office and reinstalled Snow Leopard, my Adobe Master Collection and charged to 100% I then tested the machine on battery. Again I received no more than 4 hours using BELOW recommended Mac battery settings. I contacted Apple again by telephone (another 0900 number call at my expense) and was messed around left right and centre. The employee on the telephone did not know what to do so transferred me to one of the Mac level 2 agents. I have never been spoken to so rudely and was even told that the only way I could expect 7 hours battery life from a MacBook Pro 2009 model is to use it with the lid closed. Ridiculous hey? I was also even told by one of the previous customer service agents that I could try using the machine with the battery disconnected. Even more ridiculous considering it is a unibody model.
    At this point I started doing research on the issue and found that I was far from alone with the battery issue. I have found numerous people suffering from the same issue. Below are a few links containing the same issue.

    At this point I decided to try something different, something that was not recommended or mentioned by any Apple employee, sales or technical. I decided to reformat the HD and install Leopard back on the on the machine. I then completed a battery test and low and behold my 7 hours of battery life were fully back. I think this can safely say that the issue is clearly with the OSX and not the hardware.
    I then contacted Apple customer service by phone (more 0900 numbers at my expense) I spoke to a senior Applecare advisor called XXXXX XXXXXXXX and explained my issue in full. I told xxxxxxx that I wanted this matter looking into and that I wanted a machine that would give me what is advertised using Snow Leopard, as know where on the Apple site or in the Snow Leopard documentation does it state ' Expect to lose 3 hours '
    I provided xxxxxxxx with a system info file and he sent it the Apple engineering team. A week went by and I received an email from him with the report from engineering. Engineering basically blamed it ALL on 3rd party applications, they even blamed it on the weather widget stating that it is constantly updating and will drain power. My remote access software was also blamed which was not even running in the background.
    1: The weather widget updates when you select it not constantly.
    2: The weather widget is by DEFAULT installed on a machine so thus would be classed as an Apple product in my opinion.
    That evening I decided to reformat my HD and reinstall Snow Leopard. This time I installed ONLY Apple software updates and nothing else. I then tested the battery again (getting very boring now) using the same settings as previous tests. This time I managed to have 4 hrs and 15 mins. Just 15 minutes more than what I had previously had. I then contacted xxxxxxx again and provided him with another system information file from the clean install. I explained that I had tested this with just the airport on and basic web browsing on various sites (my exact words) Another week went by and I received a call from xxxxxxx with his report from engineering. He said that Engineering wanted to know if I had tested this with basic web browsing or sat on Youtube or other flash based video streaming sites for 4 hours as this could reduce the battery life.
    As you could imagine I was furious. I repeated myself to xxxxxxx about my tests and was told that he would go back to engineering. I received another call from xxxxxxx stating that engineering are looking into it. I asked how long it would take for an answer on this and we agreed on a 2 week time frame. It is now over 2 weeks and I have sent 2 emails to xxxxxx and still have not received a reply.
    This issue has been going on since October 2009 when I first reported it. We are now in July 2010 and I am still suffering with this, as you can imaging this is unacceptable and not what one would expect from a company like Apple. My complaints summarized are below, I believe the obvious speak for themselves.
    1: There is no disclaimer on the Apple site stating that Snow Leopard will decrease the performance of a battery on a machine that did not come preinstalled with Snow Leopard. Neither is this information provided on the installation PDF instructions that come with the Snow Leopard disc.
    2: If there were such a disclaimer on the Apple site then why would I have my battery and motherboard replaced by the Apple repair team when there was clearly nothing wrong with them in the first place. Why was I never told this by any agent on the phone or in the Mac store? The answer seems clearly that this information is not available to the public or to Apple staff which is a big waste or my time as well as theirs.
    3: I have missed out on work because of having my Mac in for repair for a total of 4 weeks. As mentioned above there was clearly no need to have had the battery or motherboard replaced.
    4: I have spent money calling the 0900 numbers on numerous occasions simply getting passed around from Apple employee to Apple employee and still have no answer to my problem.
    5: I have wasted so much of my own time clean erasing my hard drive including zero out of sectors and reinstalling operating systems, not to mention other software and Apple updates. All of this comes to many hours of total wasted time at my expense when I could have been working.
    Where we stand now is that I am on the verge of taking legal proceedings with the Dutch Consumentenbond as this machine is not suitable to run with the Snow Leopard OSX when Apple advertise that it is.
    I expect either a full refund of my MacBook Pro 13" mid 2009 or an exchange for a Macbook Pro 13" that comes with Snow Leopard preinstalled with the disc in the box. I also expect to be compensated for my loss of time, money I have spent on the phone to Apple and the loss of work while the machine was in for unnecessary repair.
    I am really at the end of my patience with this issue and feel that I have been much more than fair with my reports, honesty and patience.
    I trust to hear from somebody soon regarding this issue so that we can finally put it to a close once and for all in a professional manor.
    Regards
    I received a phone call within 14 hours of sending the email from executive customer relations. They came back with new information from engineering but did not think it was acceptable as engineering were now blaming my battery decrease on the assumption that my apartment might be too hot this causing the CPU to run at a higher temperature making the battery decrease quicker. We both agreed that it was an unacceptable answer.
    The day after I received another call from them stating that engineering had now finished tests and came to the conclusion that when testing on Leopard and Snow Leopard on the MacBook Pro 2009 there was no difference in battery run time whats so ever. I found this hard to believe so asked exactly how the test was conducted. Was it conducted in the same fashion that I had spent the last 9 months talking about. ' Using below default energy saving settings with only airport on while completing basic web browsing '???
    They confirmed this was not the case, engineering had basically turned the machines on, turned the screen right down to 1 bar and left them on screen saver over night. As you can imaging I was speechless (for a few seconds)
    Apple seem consistent on NOT admitting that there is an issue with battery performance for a minority of customers. As is stands now engineering in Europe have now passed the case over to engineering in the US for further ' in-depth ' tests.
    I know there are people out there that are suffering the same issues as myself and I welcome you to please contact me with your experiences. As the more of us that complain about this make it harder for Apple to deny this and brush it under the carpet.

    Please, nobody's going to waste their time reading all that! I don't know what you possibly could have said about this issue that took up so much space, but if you can't express it more concisely, it's probably not worth reading.
    I have used SL on both a unibody MBP and an older MBP. On the older MBP, when I upgraded from Leopard to SL, I got a noticeable increase in battery life immediately. I have no such comparison on the unibody MBP, since it had SL installed to begin with, but I'll put it this way: I haven't come close to running out of power on it. I used it once for about 4 hours and still had more than a 1/3 charge. I could have easily used it for another couple hours, at least. And this was with a 17" MBP, which uses more power than your 13", and without much in the way of battery-saving going on. (Screen at full brightness, AirPort on and in use, Bluetooth on, etc.)
    It's difficult to say that SL is the problem when it clearly isn't for everyone. What your problem is, I don't know, but maybe if you posted a more concise question you'd get some answers.
    I think ..
    This thread is mainly aimed at people that are using a mid 2009 unibody MacBook Pro 13" or upwards that came pre-installed with Leopard.....
    at the beginning of the thread I made it pretty clear, if you are not affected by this then I'm happy for you, but then the thread is clearly not aimed at you. I can guarantee that I have tested this exactly the same way I did with Leopard and there is a significant decrease. I also know there are people out there that have gained battery life but there have also been many threads containing people who have lost battery life.

  • Will using for loop decrease the performance

    Hi,
    Will using for loop with a query decrease the performance.
    for r_row in (select * from table) Loop
    end loop.
    This is done inside another for loop, most of the cases it returns only one value.
    will it decrease the peformance of the procedure.
    kindly advice.......

    This is done inside another for loop, most of the cases it returns only one value.
    will it decrease the peformance of the procedure.Perhaps it is better to understand just what this PL/SQL loop construct does.
    PL/SQL is two languages. It is PL (programming logic code) like Pascal or C or Java. You can use a 2nd language inside it called SQL. The PL engine is clever enough to recognise when the 2nd language is used. And it compiles all the stuff that is needed for the PL engine to call the SQL engine, pass data to the SQL engine and get data back, etc. (compare this with the complexity of using the SQL language in Pascal or C or Java).
    So what does that loop do? The PL engine recognises the SQL SELECT statement. It creates an implicit cursor by calling the SQL engine to parse it (hopefully a soft parse) and then execute it.
    As part of the PL loop, the PL engine now calls the SQL engine to fetch the data (rows) from the cursor. With 10g and later, the PL engine is smart enough to use implicit bulk processing.
    Prior to 10g it used to fetch a row from the SQL engine, do the loop, fetch the next row, do the loop, etc. This means if there is a 1000 rows to fetch, it will call the SQL engine a 1000 times.
    With 10g and later it will fetch a 100 rows, store that in an internal buffer and then do the loop a 100 times. With a 1000 rows to fetch, it now only requires 10 bulk fetches instead of a 1000 single row fetches.
    These fetches require a context switch - as the PL engine has to step out and into the SQL engine and back, to fetch a row. This is an overhead and thus can become slow the more context switching there is.
    And this is the basics for this loop (and most other cursor loops) construct in PL/SQL.
    The ideal is to reduce the number of context switches. This is an overhead that can impact on performance.
    What about using a loop within a loop. Also "bad". This uses the outer loop to fetch data. This data is then used to drive the fetch in the inner or nested loop. So the outside loop pulls data from the SQL engine into PL variables. The inside loop pushes that very same data back to the SQL engine.
    Why? It would have been a lot faster no to pull and push that data between the loops using PL.
    It will be a lot faster doing it via SQL only. Write both loops as a single SQL statement and have the SQL engine directly drive these loops itself. This is called a JOIN in SQL. And the SQL engine can do it not only faster, but it has some froody algorithms that can be used that are even faster than a nested loop process (called merge joins, hash joins, etc).
    Bottom line. Maximise SQL. Minimise PL.*
    Do as much of your data crunching in SQL as possible. SQL is the best and fastest "place" to process data. Not PL (or Pascal/C/Java).

  • Gradually decrease volume/ adjust only fade out time

    Hi,,, 2 questions: How do I GRADUALLY decrease or increase volume in desired clip (to inaudible).
           How do I adjust the lenght of the FADE out time ONLY at the end of or beginning of a ClIP
    Howard

    To add a Fade In or Fade Out, right-click on a clip on your timeline and select the fade option.
    As I say in my books, fades are really just keyframed opacity and volume levels. If you look closely at the clips on your timeline, you'll see the keyframe points and the sloping line between them that creates the fade.
    To make your fade last longer, just move these keyframes farther apart!

  • After update to IOS 7.1 Mobile Operator decreased the performance of Iphone 5s.

    After update to IOS 7.1 Mobile Operator decreased the performance of Iphone 5s. When  the cell of my current mobile is active Iphone 5s works so bad. It is not fast and it takes 3 seconds when you wanna enter to any section. I have changed my mobile operator and it worked fine after the change.It is so interesting that how it can happen? It happened after IOS7.1. And several people have the same problem with their Iphone 5s after update to IOS7.1. And thay all using the same mobile operator that I used before.
    I have called to the customer service of mobile operator. But they say that there is no any problem with their cell. Buit in fact a lot of people have  problem on their Iphone 5s after IOS 7.1 update and they are all using the same mobile operator

  • Volume gradually decreases on 3rd gen Shuffle

    I have a brand new 3rd gen shuffle. I have notice something during long runs outdoors, the volume gradually decreases until it is barely audible. Volume button doesn't help. Battery is fine though. When I come indoors after a while, sound returns to normal. This seems to happen when it is cold. Any suggestions?

    I'm glad and sorry to find this post.....I had bought a used 4gig shuffle on Ebay/ I was having problems with the volume. I thought that because it was used that it must be problematic, so I bought a brand new one.
    same problem!
    by the way, I only use the I-Pod at the gym, and before I even have a chance to sweat the volume is so low, no matter what setting I use. since I like my music loud for workouts, I'm really upset...now I own 2 inferior I-pods. I am not crazy about the volume control on the headphones......but I would'nt mind that much if it worked!
    do you think I can get a refund or exchange? this situation is unacceptable. I can't use it at such a low volume........thanks, larrytorre

    ps: how can i get the old kernel26 pakage?
    If you haven't cleared your pacman cache yet you should find an older version in /var/cache/pacman/pkg/. You can 'downgrade' via this command then:
    pacman -U /var/cache/pacman/pkg/kernel26-2.6.29.1-2-i686.pkg.tar.gz
    If you already cleared your cache, or not keeping one, you could search some mirrors for an older version or i could upload it for you .
    I'll do some testing and report back with my xorg logs. I don't have KMS enabled (used to have it enabled, but disabled it to see if it was causing the framedrop)
    Edit:
    Alright, i'm back with the logs! Seems to be some weird things happening, but i don't have enough knowledge to pinpoint where the problem lies.
    Here are the logs:

    Kernel26 2.6.29.1-2
    II) [drm] loaded kernel module for "i915" driver.
    There also seems to be some problem when setting tiling with the latest kernel version.

  • Problems with Full loads/Decreased query performance in Prod

    We have a table which serves as a base for a complex view. The table has roughly around 10 Million records and its a daily full load(I know, that delta loads are much better for handling large sets of data, but this information is very dynamic and with the business time constraints and project deliverables, the best decision was to do a Full load).
    This is the process we follow:
    > Drop Indexes (All columns individual indexes which are used inside the complex view as joins)
    > Truncate table
    > Load data
    > Recreate indexes.
    All the above steps are performed from SAP Dataservices Thru scripts and sql() function to execute the command, no manual intervention what so ever.
    After the job is successfully completed, the view doesn't refresh at all(It sits there forever). The same job when run across same volume of production data in Test environment performs much faster.
    Then, how do I refresh the view is manually log into SQL Developer, drop all the indexes on the parent table, and re-create all the indexes in the same order as Dataservices script. It performs very well after till the next load (the next morning).
    Any suggestions would be very helpful.
    My main question is why does it run faster, when I drop and recreate the indexes? and doesnt complete when the indexes are created by the SQL() from data services tool.
    Tried:
    Explain Plan(in dev, Test, Prod): Query cost vaired accross environments but returned results with same return times (In Production after manual Index creation)
    Tuning advisor (Only in Test) DBA evaluated it to be good.
    Thanks

    DB Version Oracle 11.0.7

    BluShadow and Harman
    Thank You!
    Im using a regular view, not a materialized view. and yes the query plan is completely different from Test and Production. In test the query was completely running on Hash based joins whereas in Production its using Nested Joins in the execution plan.
    Will try to gather statistics after the load and as per BluShadow, will look on the way of writing a function that makes a call to Database.
    Thank you all for taking sometime. I will try to test this out starting today and will extend tests over a couple of days.

  • Decreasing Battery Performance

    My MBP 17 Unibody battery was working fine for the first 1-9 cycles and I was getting about 7 to 7.5 hours out of it, but now from 10 cycles my battery life *****. I can only get up to a maximum of 4 hours after a full change and recalibration (used it till it shut down, waited 5 hours then charged it overnight for 7 hours straight without any interuptions). This is very frustrating and I'm trying to figure out why this is? I am on 'better battery performance' and I have no CPU intensive programs running and my display is on the lowest level setting.
    Any help or suggestions would be greatly appreciated...

    I get the same "problem", and it is frustrating as he**. My MBP is about 2 months old, I use it every day, and I probably charge it once a day. This gives me a cycle count at about 60 now (holidays included - where the computer has not worked a lot). My battery is already going down, I'll be lucky to get three hours of use. And there is another problem: Yesterday I was at 25% of battery (the icon was still black), I took a leak, and made a cup of tea - and when I returned to my computer the icon was at 10%, and when I tried to keep working it went to 6% and then came the "low battery warning".
    Apple gives you 300 cycles, and after that you are on your own - and have to buy a new battery... I actually work on my computer, I do not sit at the coffee house surfing the web. I am currently graduating, doing my masters in graphic design, and is using my computer a lot - by this rate the battery will be dead within six months.
    On apple Store, you can see someone having written a review of the MBP battery, stating that his battery went from 100-94% in a WEEK. That is just sad.

  • Decreased speed performance without battery?

    Hello to the helpful stars out there...
    Having had problems with my Powerbook G4 battery, I found out it was one of those having been recalled by Apple last summer. I have ordered a new battery and am running the Powerbook now with the net plug, but it seems to me, that it's performance is much slower.
    Is that possible - even though it seems very unlikely to me - or does my Powerbook have another problem?
    Thank you for your help ...
    Aluminium Powerbook G4, 1.67 Ghz,   Mac OS X (10.4.8)  

    There are different sets of performances that can be set in:
    System Preferences > Energy Saver
    You can select a seperate set for Battery Power, usually lower CPU performance to save battery, and while under the AC Power Adapter.
    Might want to have a look at your settings.
    Welcome to the Discussions btw!

  • Thread Pool's decreasing application performance

    Hi,
    In my application, I need to make 10,000 threads for network calls at one instant and release the threads after downloading content.
    Content downloading of individual thread consumes less than 1min.
    When I try this using Timer Task and normal Threads, it works perfectly.
    But after introducing ThreadPool (initial :20,000 ; maximum: 50,000) , the response has degraded.
    Is there any limitations or known issues similar to this for thread pool's.
    Thanks!

    You'll hit problems at that level long before the number of threads becomes a problem.

    When I try this using Timer Task and normal Threads, it works perfectly.What are "normal Threads"? How many operations are you running in parallel here?

  • Labview performance suffering with analog input

    Hello,
    I am using a PCI-6036E and a cDAQ-9172 with LabView 8.0. I have created a VI that systematically writes four different digital outputs, three to the PCI-6036E and one to the cDAQ-9172.
    Just recently I added a thermocouple to the mix, using an analog input on the PCI-6036E to monitor temperature. Since doing so, I have noticed that the entire VI runs extremely slowly.
    Before installing the thermocouple, the VI slowed down a bit if left to run continuously (for days at a time). Now, however, the VI slows down a great deal if left to run for more than a few minutes. It is so bad that the "Elapsed Time" display will not properly display the elapsed time.
    Because this application will be run for days, even weeks at a time without being stopped, this gradual decrease in performance is a huge problem. The application needs to run very accurately and precisely. I have attached my VI below. Is there any way to fix this issue? Any help is greatly appreciated, as I am new to LabView.
    Thanks,
    Nick

    I didn't look at the code (yet), but do you have a slow analog samplerate?

  • Major Performance Issues in Flash 8

    I have been experiencing major slowdown in the Flash 8
    authoring tool... I am working with large files (about 40-50mb
    .fla).
    My system specs aren't too bad but maybe not enough?
    1.5Ghz Pentium M
    512mb RAM
    1024mb virtual memory...
    Is there anything that specifically causes Flash to slow way
    down? I'm thinking about tweaking my system (either settings or by
    upgrading hardware) but I don't know what would help Flash with
    larger projects. I'm assuming that more RAM would speed things up,
    but I don't want to jump to that assumption and buy it without
    knowing for sure...
    ...any ideas?

    Yes... more graphics = heavier load...
    ...obviously.
    However the performance issues here I'm talking about aren't
    just slight slowdown issues. It is a MAJOR slowdown problem that
    occurs suddenly. This means that once I hit a certain filesize,
    Flash slows down and will not respond for MINUTES. If it were a
    simple "you added more graphics" problem, then it would show a
    gradual decrease in performance.
    What I was really wanted to know is what is the weak link
    concerning Flash performance? Is it RAM, processor speed, or
    something else?
    I can upgrade, but I'm not buying a new multi-processor
    machine...it's not feasible, and not to mention it's a huge
    overkill.

  • Xcelsius Engage: Issue with dynamic visibilty of data in dashboard

    Hi,
    We have a requirement for a dashboard where data for 5 Sites need to be displayed as per 17 KPIs and 12 different rolling months.
    Raw sample data looks like below-
    SITE  KPI        ActYTD  Act(Pre Month) PlanYTD  Plan(Prev Month)  VarianceYTD Variance(Pre Month)
    A       On-Time   76.7         82.92                  111.50       109.50             -1                    -1
    B       Delay       73.70       80.00                   79.75        77.75             -1                     1
    There are 5 different Sites and 17 different KPIs.
    Based on the raw data that we get from BI (7.0 query output), we manipulate it in MS excel, using some lookups and formulae to obtain certain values, store them in designated sheets and then Xcelsius (different components) use these sheets as source.
    We are having three levels of navigation-
    1. Main screen listing all KPIs site wise and months ( the site and months could be selected from Combo boxes at the top). The KPIs are bind to a list view, each row is a selectable KPI leading to level two navigation.
    2. Level two contains the details for each KPI ( values and trend chart). Selection in the chart for a Site leads to level 3 navigation.
    3. Level 3 screen contains data by KPI and by Site for 12 rolling months ( The sites could be changed from a drop-down).
    There are custom navigation buttons (home/back) to enable navigations between the screens.
    We are using 3 panel containers, 2 list views, 4-5 combo boxes and some hidden button ( with dynamic visibilty).
    The workbook has 8-9 different sheets, though the Xcelsius componets are bound to only 3 sheets.
    Things work fine till we select 14th KPI , but Xcelsius starts behaving awkwardly when we select 15th KPI and further.For the selected KPI, the level two screen would load for a flash of a second and then the control comes back to level 1 screen. We do not face this issue till 14th KPI.
    In-order to eliminate possibiltes we did the following-
    1. Changed the order of KPIs - issue persists
    2. Changed the Excel option " Max. no of Rows" to 4000- issue persists
    3. Decreased the amount of data to be loaded - issue persists ( though at max we are loading data for 2000 rows)
    4. Decreased the no. of KPIs to 14 in level 1 list view - all works fine.
    We have not noticed any gradual decrease in performance/load time till 14th KPI but everything goes for a toss when the 15th KPI is displayed.
    We are on the latest Xcelsius patch ( patch 3).
    We would appreciate any pointers/help to resolve this issue.
    Thanks in advance for your time.
    Best Regards,
    Bansi.
