count(*) performance issue

Hi,
which will be more performance friendly and WHY??(Also is ther any difference between them??)
1. select count(col1) from tbl
OR
2. select count(*) from tbl
OR
3. select count(rowid) from tbl
rgds,
s

Hi,

  • Performance issue when using select count on large tables

    Hello Experts,
    I have a requirement where i need to get count of data  from a database table.Later on i need to display the count in ALV format.
    As per my requirement, I have to use this select count inside a nested loops.
    Below is the count snippet:
    LOOP at systems assigning <fs_sc_systems>.
    LOOP at date assigning <fs_sc_date>.
    SELECT COUNT( DISTINCT crmd_orderadm_i~header )
       FROM crmd_orderadm_i
       INNER JOIN bbp_pdigp
           ON crmd_orderadm_iclient EQ bbp_pdigpclient               "MANDT is referred as client
         AND crmd_orderadm_iguid  EQ bbp_pdigpguid
         INTO w_sc_count
    WHERE crmd_orderadm_i~created_at BETWEEN <fs_sc_date>-start_timestamp
         AND <fs_sc_date>-end_timestamp
         AND bbp_pdigp~zz_scsys   EQ <fs_sc_systems>-sys_name.
    endloop.
    endloop.
    In the above code snippet,
    <fs_sc_systems>-sys_name is having the system name,
    <fs_sc_date>-start_timestamp is having the start date of month
    and <fs_sc_date>-end_timestamp is the end date of month.
    Also the data in tables crmd_orderadm_i and bbp_pdigp is very large and it increases every day.
    Now,the above select query is taking a lot of time to give the count due to which i am facing performance issues.
    Can any one pls help me out to optimize this code.
    Thanks,
    Suman

    Hi Choudhary Suman ,
    Try this:
    SELECT crmd_orderadm_i~header
      INTO it_header                 " interna table
      FROM crmd_orderadm_i
    INNER JOIN bbp_pdigp
        ON crmd_orderadm_iclient EQ bbp_pdigpclient
       AND crmd_orderadm_iguid   EQ bbp_pdigpguid
       FOR ALL ENTRIES IN date
    WHERE crmd_orderadm_i~created_at BETWEEN date-start_timestamp
                                          AND date-end_timestamp
       AND bbp_pdigp~zz_scsys EQ date-sys_name.
        SORT it_header BY header.
        DELETE ADJACENT DUPLICATES FROM it_header
        COMPARING header.
        describe table it_header lines v_lines.
    Hope this information is help to you.

  • Performance Issue - higher fetch count

    Hi,
    The database version is 10.2.0.4.
    Below is the tkprof report of an application session having performance issue.
    We shared the screens of application team and were able to see the lag in report generation.
    It shows an elapsed time of 157 seconds, however the same query when executed in database is taking fractions of a second.

    After many days of tests, I wanna share my results with community and comment them.
    CPU Introduction
    I tested my cpu and pushed it at maximum speed to understand where is the limit, can I reach this limit and I've logged precisely all result in graph (See pictures 1).
    Intro : I tested my E5-XEON 2687W (8 Cores Hyperthread - 16 threads) to know if programs can use the maximum of it.  I used Prime 95 to get the result.  // I know this seem to be ordinary, but you will understand soon...
    The result : Yes, I can get 100% of my CPU with 1 program using 20 threads in parallel.  The CPU gives everything it can !
    Comment : I put 3 IO (cpu, disk, ram) on the graph of my computer during the test...
    (picture 1)
    Disk Introduction
    I tested my disk and pushed it at maximum speed to understand where is the limit and I've logged precisely all result in graph (See pictures 2).
    Intro : I tested my RAID 0 556GB (LSI MegaRAID 9260-8i SATA3 6GB/s 5 disks with Fastpath Chip Installed) to know if I can reach the maximum % disk usage (0% idle Time)
    The result : As you can see in picture 2, yes, I can get the max of my drive at ~ 1.2 Gb/sec read/write steady !
    Comment : I put 3 IO (cpu, disk, ram) on the graph of my computer during the test to see the impact of transfering many Go of data during ~10 sec...
    (picture 2)
    Now, I know my limits !  It's time to enter deeper in the subject !
    PPBM5 (H.264) Result
    I rendered the sequence (H.264) using Adobe Media Encoder.
    The result :
    My CPU is not used at 100%, the turn around 50%
    My Disk is totally idle !
    All the process usage are idle except process of (Adobe Media Encoder)
    The transfert rate seem to be a wave (up and down).  Probably caused by (Encrypt time....  write.... Encrypt time.... write...)  // It's ok, ~5Mb/sec during transfert rate !
    CPU Power management give 100% of clock to CPU during the encoding process (it's ok, the clock is stable during process).
    RAM, more than enough !  39 Go RAM free after the test !  // Excellent
    ~65 thread opened by Adobe Media Encoder (Good, thread is the sign that program try to using many cores !)
    GPU Load on card seem to be a wave also ! (up and down)  ~40% usage of GPU during the process of encoding.
    GPU Ram get 1.2Go of RAM (But with GTX 680, no problem and Quadro 6000 with 6 GB RAM, no problem !)
    Comment/Question : CPU is free (50%), disks are free (99%), GPU is free (60%), RAM is free (62%), my computer is not pushed at limit during the encoding process.  Why ????  Is there some time delay in the encoding process ?
    Other : Quadro 6000 & GTX 680 gives the same result !
    (picture 3)
    PPBM5 (Disk Test) Result (RAID LSI)
    I rendered the sequence (Disk Test) using Adobe Media Encoder on my RAID 0 LSI disk.
    The result :
    My CPU is not used at 100%
    My Disk wave and wave again, but far far from the limit !
    All the process usage are idle except process of (Adobe Media Encoder)
    The transfert rate wave and wave again (up and down).  Probably caused by (Buffering time....  write.... Buffering time.... write...)  // It's ok, ~375Mb/sec peak during transfert rate !  Easy !
    CPU Power management give 100% of clock to CPU during the encoding process (it's ok, the clock is stable during process).
    RAM, more than enough !  40.5 Go RAM free after the test !  // Excellent
    ~48 thread opened by Adobe Media Encoder (Good, thread is the sign that program try to using many cores !)
    GPU Load on card = 0 (This kind of encoding is GPU irrelevant)
    GPU Ram get 400Mb of RAM (No usage for encoding)
    Comment/Question : CPU is free (65%), disks are free (60%), GPU is free (100%), RAM is free (63%), my computer is not pushed at limit during the encoding process.  Why ????  Is there some time delay in the encoding process ?
    (picture 4)
    PPBM5 (Disk Test) Result (Direct in RAMDrive)
    I rendered the same sequence (Disk Test) using Adobe Media Encoder directly in my RamDrive
    Comment/Question : Look at the transfert rate under (picture 5).  It's exactly the same speed than with my RAID 0 LSI controller.  Impossible !  Look in the same picture the transfert rate I can reach with the ramdrive (> 3.0 Gb/sec steady) and I don't go under 30% of disk usage.  CPU is idle (70%), Disk is idle (100%), GPU is idle (100%) and RAM is free (63%).  // This kind of results let me REALLY confused.  It's smell bug and big problem with hardware and IO usage in CS6 !
    (picture 5)
    PPBM5 (MPEG-DVD) Result
    I rendered the sequence (MPEG-DVD) using Adobe Media Encoder.
    The result :
    My CPU is not used at 100%
    My Disk is totally idle !
    All the process usage are idle except process of (Adobe Media Encoder)
    The transfert rate wave and wave again (up and down).  Probably caused by (Encoding time....  write.... Encoding time.... write...)  // It's ok, ~2Mb/sec during transfert rate !  Real Joke !
    CPU Power management give 100% of clock to CPU during the encoding process (it's ok, the clock is stable during process).
    RAM, more than enough !  40 Go RAM free after the test !  // Excellent
    ~80 thread opened by Adobe Media Encoder (Lot of thread, but it's ok in multi-thread apps!)
    GPU Load on card = 100 (This use the maximum of my GPU)
    GPU Ram get 1Gb of RAM
    Comment/Question : CPU is free (70%), disks are free (98%), GPU is loaded (MAX), RAM is free (63%), my computer is pushed at limit during the encoding process for GPU only.  Now, for this kind of encoding, the speed limit is affected by the slower IO (Video Card GPU)
    Other : Quadro 6000 is slower than GTX 680 for this kind of encoding (~20 s slower than GTX).

    Encoding single clip FULL HD AVCHD to H.264 Result (Premiere Pro CS6)
    You can look the result in the picture.
    Comment/Question : CPU is free (55%), disks are free (99%), GPU is free (90%), RAM is free (65%), my computer is not pushed at limit during the encoding process.  Why ????   Adobe Premiere seem to have some bug with thread management.  My hardware is idle !  I understand AVCHD can be very difficult to decode, but where is the waste ?  My computer want, but the software not !
    (picture 7)
    Render composition using 3D Raytracer in After Effects CS6
    You can look the result in the picture.
    Comment : GPU seems to be the bottle neck when using After Effects.  CPU is free (99%), Disks are free (98%), Memory is free (60%) and it depend of the setting and type of project.
    Other : Quadro 6000 & GTX 680 gives the same result in time for rendering the composition.
    (picture 8)
    Conclusion
    There is nothing you can do (I thing) with CS6 to get better performance actually.  GTX 680 is the best (Consumer grade card) and the Quadro 6000 is the best (Profressional card).  Both of card give really similar result (I will probably return my GTX 680 since I not really get any better performance).  I not used Tesla card with my Quadro, but actually, both, Premiere Pro & After Effects doesn't use multi GPU.  I tried to used both card together (GTX & Quadro), but After Effects gives priority to the slower card (In this case, the GTX 680)
    Premiere Pro, I'm speechless !  Premiere Pro is not able to get max performance of my computer.  Not just 10% or 20%, but average 60%.  I'm a programmor, multi-threadling apps are difficult to manage and I can understand Adobe's programmor.  But actually, if anybody have comment about this post, tricks or any kind of solution, you can comment this post.  It's seem to be a bug...
    Thank you.

    Patrick,
    I can't explain everything, but let me give you some background as I understand it.
    The first issue is that CS6 has a far less efficient internal buffering or caching system than CS5/5.5. That is why the MPEG encoding in CS6 is roughly 2-3 times slower than the same test with CS5. There is some 'under-the-hood' processing going on that causes this significant performance loss.
    The second issue is that AME does not handle regular memory and inter-process memory very well. I have described this here: Latest News
    As to your test results, there are some other noteworthy things to mention. 3D Ray tracing in AE is not very good in using all CUDA cores. In fact it is lousy, it only uses very few cores and the threading is pretty bad and does not use the video card's capabilities effectively. Whether that is a driver issue with nVidia or an Adobe issue, I don't know, but whichever way you turn it, the end result is disappointing.
    The overhead AME carries in our tests is something we are looking into and the next test will only use direct export and no longer the AME queue, to avoid some of the problems you saw. That entails other problems for us, since we lose the capability to check encoding logs, but a solution is in the works.
    You see very low GPU usage during the H.264 test, since there are only very few accelerated parts in the timeline, in contrast to the MPEG2-DVD test, where there is rescaling going on and that is CUDA accelerated. The disk I/O test suffers from the problems mentioned above and is the reason that my own Disk I/O results are only 33 seconds with the current test, but when I extend the duration of that timeline to 3 hours, the direct export method gives me 22 seconds, although the amount of data to be written, 37,092 MB has increased threefold. An effective write speed of 1,686 MB/s.
    There are a number of performance issues with CS6 that Adobe is aware of, but whether they can be solved and in what time, I haven't the faintest idea.

  • Is there a recommended limit on the number of custom sections and the cells per table so that there are no performance issues with the UI?

    Is there a recommended limit on the number of custom sections and the cells per table so that there are no performance issues with the UI?

    Thanks Kelly,
    The answers would be the following:
    1200 cells per custom section (NEW COUNT), and up to 30 custom sections per spec.
    Assuming all will be populated, and this would apply to all final material specs in the system which could be ~25% of all material specs.
    The cells will be numeric, free text, drop downs, and some calculated numeric.
    Are we reaching the limits for UI performance?
    Thanks

  • Performance issues with pipelined table functions

    I am testing pipelined table functions to be able to re-use the <font face="courier">base_query</font> function. Contrary to my understanding, the <font face="courier">with_pipeline</font> procedure runs 6 time slower than the legacy <font face="courier">no_pipeline</font> procedure. Am I missing something?

    Like:
    - a database version
    - how did you test
    - what data do you have, how is it distributed, indexed
    and so on.
    If you want to find out what's going on then use a TRACE with wait events.

  • Performance Issues with Photoshop CS6 64-Bit

    Hello -
    Issue at hand: over the course of the last few weeks, I have noticed significant issues with performance since the last update to PS CS6 via the Adobe Application Manager, ranging from unexpected shut downs to bringing my workstation to a crawl (literally, my cursor seems to crawl across my displays). I'm curious as to if anyone else is experiencing these issues, or if there is a solution I have not yet tried. Here is a list of actions that result in these performance issues - there are likely more that I have either not experienced due to my frustration, or have not documented as occuring multiple times:
    Opening files - results in hanging process, takes 3-10 seconds to resolve
    Pasting from clipboard - results in hanging process, takes 3-10 seconds to resolve
    Saving files - takes 3-10 seconds to open the dialog, another 3-10 seconds to return to normal window (saving a compressed PNG)
    Eyedropper tool - will either crash Photoshop to desktop, or take 5-15 seconds to load
    Attempting to navigate any menu - will either crash Photoshop to desktop, or take 5-15 seconds to load
    Attempts I've taken to resolve this matter, which have failed:
    Uninstalled all fonts that I have added since the last update (this was a pain in the ***, thank you Windows explorer for being glitchy)
    Uninstall application and reinstall application
    Use 32-bit edition
    Changing process priority to Above Normal
    Confirm process affinity to all available CPU cores
    Change configuration of Photoshop performance options

    This issue is costing me time I could be working every day, and I'm about ready to begin searching for alternatives and cancel my membership if I can't get this resolved.

    Based on my initial assessment of the code, it looks like you are utilizing the "slow by slow" method. It is often termed "slow by slow" because it is one of the most INefficient ways of doing data processing. The "slow by slow" method uses CURSOR FOR LOOPs to loop through entire record sets and process them one at a time. In your case it looks like you are using NESTED FOR LOOPs which could exacerbate the problem.
    I recommend you re-think your approach and try and do everything in a single, or a few SQL statements if possible and avoid the procedural logic.
    If you can post your business requirements, and sample data we may be able to help you achieve your goal.
    HTH!

  • Performance issue with pl/sql code

    Hi Oracle Gurus,
    I am in need of your recommendations for a performance issue that I am facing in production envrionment. There is a pl/sql procedure which executes with different elapsed time at different executions. Elapsed Times are 30minutes , 40 minutes, 65 minutes , 3 minutes ,3 seconds.
    Expected elapsed time is maximum of 3 minutes. ( But some times it took 3 seconds too...! )
    Output on all different executions are same that is deletion and insertion of 12K records into a table.
    Here is the auto trace details of two different scenarios.

              -------------------------------------------------------------For security reasons, I cannot share the actual code. Its a report generating code that deletes and load the data into table using insert into select statement.
    Delete from table ;
    cursor X to get the master data ( 98 records )
    For each X loop
    insert into tableA select * from tables where a= X.a and b= X.b and c=X.c ..... ;
    -- 12 K records inserted on average
    insert into tableB select * from tables where a= X.a and b= X.b and c=X.c ..... ;
    -- 12 K records inserted on average
    end loop ;1. The select query is complex with bind variables ( explain plan varies for each values )
    2. I have checked the tablespace of the tables involved, it is 82% used. DBA confirmed that it is not the reason.
    3. Disk reads are high during long execution.
    4. At long running times, I can see a db sequential read wait event on a index object. This index is on the table where data is inserted.
    All I need to find is why this code is taking 3 seconds and 60 minutes on the same day and on the consecutive executions ?
    Is there any other approach to find the root cause of this behaviour and to fix it ? Kindly adivse.
    Thanks in advance your help.
    Regards,
    Hari

    Hi Oracle Gurus,
    I am in need of your recommendations for a performance issue that I am facing in production envrionment. There is a pl/sql procedure which executes with different elapsed time at different executions. Please reedit your post and add some code tags around the trace information. This would improve readability greatly and will help us to help you
    example
    {<b></b>code}
    select * from dual;{<b></b>code}
    Based upon your description I can imagine two things.
    a) The execution plan for the select query does change frequently.
    A typical reason can be not up to date statistics.
    b) Some locking / wait conflict. For example upon a UK index.
    Are there any other operations going on while it is slow? If anybody inserts a value, then your session will wait, if the same (PK/UK) value also is to be inserted.
    Those wait events can be recognized using standard tools like oracle sql developer or enterprise manager while the query is slow.
    Also go through the links that are in the FAQ. They tell you how to get better information for makeing a tuning request.

  • Major performance Issues after upgrading to 10.9.2

    Hi,
    I have been having major performance issues almost preventing me from using the computer at times.  I suspect I don't have enough memory to run Maverick as the computer was great before I upgraded.
    If any experts or people with ideas for me to speed up the computer, please respond.  If you think the only way to improve performance is add memory or revert back to a previous version of OSX that I have a backup for, let me know.

    The performance issues are due to third party software. Mavericks at the minimum requires 2GB's of RAM but I don't think that's the issue. And you can upgrade RAM anytime.
    MacKeeper should be uninstalled. It does far more harm than good.
    Do not install MacKeeper: Apple Support Communities

    Keep an eye on available disk space.
    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. Less can slow your Mac down.

  • Performance issue using webelements and crystal

    We have 2 reports named, u201CDAMAGE_REPORTSu201D AND u201CTDI_CHARTu201D
    DAMAGE_REPORTS
    There are 13 dynamic or static Prompts created using Webelements .After clicking on submit button(using
    webelement)  by selecting the prompt values, TDI_CHART report will get opened below the u201CDAMAGE_REPORTSu201D report.
    TDI_CHART
    TDI_CHART created using free-hand SQL which contains 2 commands
            1. Command-SQL is created based on two categories.
                  Trend -Trend By Month ,Trend By Quarter,Trend By Week
                   Non-Trend- Current Month ,Current Year to Date,Last Year to Date,Current Quarter,Last
                                 Quarter,Current Week,Last Week,Last Month,Last Year Total
                 Charts,Cross-tabs and table information is coming from this Query
           2.Image count-contains number of images information based on the prompt selection and it acts as a 
                  URL(opendocument) in the report to open TDI_THUMBNAIL report to display the thumbnail images.
    Report information
    TDI_CHART Report contains 8 charts,4 cross-tabs, summary information showing in table format(Detail
           section) and2 open document links(1.For image count 2.Export to excel(which shows the detail information
            of summary table)
    Description
    If the selection is Non-Trend Value from the Time period parameter , corresponding Chart will be shown along   with table information.(Table information is only required for Non-Trend Values).
    If the Selection is Trend Value from the Time period parameter,the corresponding cross tab and chart will be shown and others will get suppressed.
    Problem Area
    After the prompt selection from u201CDamage_Reportsu201D, TDI_CHART report is taking around 1min 30 sec to show the chart and table or cross-tab.
    In Database when we execute the above queries, it comes in 12 secs but whereas in reports it takes 1min 30 sec,can you guide us some steps to bring down this time?

    hello Mufiza,
    copy the url created at the step "After the prompt selection from u201CDamage_Reports".
    paste this url into a new browser window and press enter.
    what is the time to return this report?...this time should also be 1.5 minutes.
    it sounds like you are using 2 commands in the same report. this will often cause performance issues, just like linking two stored procedures together or linking two disparate datasources together.
    this would not be an issue related to webelements but related to the design of your target report.

  • Performance issue on the sys.dba_audit_session

    i have the following query which is taking long time and had performance issue.
    SELECT TO_CHAR(current_timestamp AT TIME ZONE 'GMT', 'YYYY-MM-DD HH24:MI:SS TZD') AS curr_timestamp, COUNT(username) AS
    failed_count
    FROM sys.dba_audit_session
    WHERE returncode != 0
    AND timestamp >= current_timestamp - TO_DSINTERVAL('0 0:30:00')
    call count cpu elapsed disk query current rows
    Parse 1 0.01 0.04 0 0 0 0
    Execute 1 0.00 0.00 0 0 0 0
    Fetch 2 68.42 216.08 3943789 3960058 0 1
    total 4 68.43 216.13 3943789 3960058 0 1
    The view dba_audit_session is a select from the view dba_audit_trail. If you
    look at the definition of dba_audit_trail it does a CAST on the ntimestamp#
    column. Therefore disabling index access because there is not a function
    based index on ntimestamp#. I am not even sure a function based index would
    work to match what the view does.
    cast ( /* TIMESTAMP */
    (from_tz(ntimestamp#,'00:00') at local) as date),
    To get index access the metric would have to avoid the use of the view. I have changed the query like this.
    SELECT /*+ INDEX(a I_AUD3) */ TO_CHAR(current_timestamp AT TIME ZONE 'GMT', 'YYYY-MM-DD
    HH24:MI:SS TZD') AS curr_timestamp, COUNT(userid) AS failed_count
    FROM sys.aud$ a
    WHERE returncode != 0
    and action# between 100 and 102
    AND ntimestamp# >= systimestamp at time zone 'GMT' - 30/1440
    is it correct way to di it?
    could you comment on this ?

    The query is run by grid Control (or DBConsole) to count the metric related to audit sessions which is ON by default in 11g. To decrease the impact of this query you should purge the aud$ table regularly.
    Best way is to use DBMS_AUDIT_MGMT to periodically purge the data older than "whatever date". If you don't need the audit infor, you can simply truncate aud$.

  • Socket based application - Performance Issues - Suggestions Needed

    Hi All,
    We have an application which basically has been developed using core java. Here is a high level information about the application:
    a) It opens a serversocket which allows clients to connect to it.
    b) For every new client connection, a separate thread is created and this thread deals with requests from clients, processing the data and replying back to clients.
    c) Each socket is polled continuously and sockettimeout is 2 seconds. If there is a timeout, we handle the situation and socket is again read. So basically sockets is read every 2 seconds. If number of timeouts reaches a configurable value, we close the connection and thread is dropped as well.
    d) In production, three instances of this application are running with the help of a cisco load balancer. It is there for last 5 years.
    However there has always been some minor performance isssues and we have sorted them out using different types of garbage collectors, by introducing hardware load balancers, upgrading the code for new Java versions. It is currently running on 1.4.2.
    However there has always been some performance issues and today while googling over internet I came across following on the bea website which says that core java sockets are not as efficients as native API. BEA has implemented its own APIs for weblogic. My queries are:
    a) Are there any better Java Socket/network API (for solairs, I know Java is plateform independenet but there could be lib which also using native libs) which are much more efficient than Core Java.
    b) We are getting the InputStream/OutputStream and creating objects of DataInputStream/DataOutputStream to read the data 'Byte-By-Byte'. Each byte can have different information thats why it is required. Are there any better way of getting info than what we are currently doing.
    c) As I mentioned, we are continously polling the socket for read operation with a timeout value of 2 seconds. What is the better among the following from performance point of view: (1) Frequent read operation with a lesser timeout value or (2) Less Frequent read operations with larger timeout value. (3) Any better idea??
    Please suggest few things or pointers which I could do to improve the performance of the applcations. Many thanks.
    Thanks,Akhil
    From BEA website:-
    "Although the pure-Java implementation of socket reader threads is a reliable and portable method of peer-to-peer communication, it does not provide the best performance for heavy-duty socket usage in a WebLogic Server cluster. With pure-Java socket readers, threads must actively poll all opened sockets to determine if they contain data to read. In other words, socket reader threads are always "busy" polling sockets, even if the sockets have no data to read. This unnecessary overhead can reduce performance."

    My recommendations:
    - Always use a BufferedInputStream and BufferedOutputStream around the socket streams
    - Increase the socket send and receive buffers to at least 32k if you are on a Windows platform where the default is a ridiculous 8k, which hasn't been enough for about 15 years.
    - Your 2-second timeout is far too short. Increase it to at least 10 seconds.
    - Your strategy of counting up to N short timeouts of S seconds each is completely pointless. Change it to one single timeout of N*S seconds. There is nothing to be gained by the complication you have introduced to this.

    When there is a large number of records (100,000+) in the Items table and say ~10 complicated conditions concatenated in WHERE clause, I get the result about 2 seconds in my case. The problem is when very few conditions are met, f.e. when I get only
    10 Items from 100,000.
    How can I improve the performace in this "Get my items" case?

  • Performance issue in browsing SSAS cube using Excel for first time after cube refresh

    Hello Group Members,
    This is a continuation of my earlier blog question -
    https://social.msdn.microsoft.com/Forums/en-US/a1e424a2-f102-4165-a597-f464cf03ebb5/cache-and-performance-issue-in-browsing-ssas-cube-using-excel-for-first-time?forum=sqlanalysisservices
    As that thread is marked as answer, but my issue is not resolved, I am creating a new thread.
    I am facing a cache and performance issue for the first time when I try to open a SSAS cube connection using Excel (using Data tab  -> From Other Sources --> From Analysis Services) after daily cube refresh. In end users system (8 GB RAM but around
    4GB available RAM), for the first time, it takes 10 minutes to open the cube. From next run onwards, its open up quickly within 10 secs.
    We have daily ETL process running in high end servers. The configuration of dedicated SSAS cube server is 8 core, 64GB RAM. In total we have 4 cube DB - out of which for 3 is full cube refresh and 1 is incremental refresh. We have seen after daily cube
    refresh, it takes 10 odd minutes to open the cube in end users system. From next time onwards, it opens up really fast with 10 secs. After cube refresh, in server systems (32 GB RAM, around 4GB available RAM), it takes 2 odd minutes to open the cube.
    Is there, any way we could reduce the time taken for first attempt ?
    As mentioned in my previous thread, we have already implemented a cube wraming cache. But, there is no improvement.
    Currently, the cumulative size of the all 4 cube DB are more than 9 GB in Production and each cube DB having 4 individual cubes in average with highest cube DB size is 3.5 GB. Now, the question is how excel works with SSAS cube after
    daily cube refresh?
    Is it Excel creates a cache of the schema and data after each time cube is refreshed and in doing so it need to download the cube schema in Excel's memory? Now to download the the schema and data of each cube database from server to client, it will take
    a significant time based on the bandwidth of the network and connection.
    Is it anyway dependent to client system RAM ? Today the bigest cube DB size is 3.5 GB, tomorrow it will be 5-6 GB. Now, though client system RAM is 8 GB, the available or free RAM would be around 4 GB. So, what will happen then ?
    Best Regards, Arka Mitra.

    Could you run the following two DMV queries filling in the name of the cube you're connecting to. Then please post back the row count returned from each of them (by copying them into Excel and counting the rows).
    I want to see if this is an issue I've run across before with thousands of dimension attributes and MDSCHEMA_CUBES performance.
    select [HIERARCHY_UNIQUE_NAME]
    from $system.mdschema_hierarchies
    where CUBE_NAME = 'YourCubeName'
    select [LEVEL_UNIQUE_NAME]
    from $system.mdschema_levels
    where CUBE_NAME = 'YourCubeName'
    Also, what version of Analysis Services is it? If you connect Object Explorer in Management Studio to SSAS, what's the exact version number it says on the top server node?
