Performance issues logging on to Workspace 11.1.2.1

Hi All,
We have a distributed install of 11.1.2.1 (2 HSS, 3 PLN, 3HFM, 3 Workspace, 2 FDM servers) and facing significant performance issues:
- Logging on to the Workspace as an external user takes 5 min
- Logging on to the AAS console as an external user takes over 2 min
- Opening HBRs in AAS takes a couple of minutes
- Logging on to HSS as an external user takes over a min
Logging on as a native user takes around 30 seconds.
We have disabled compoments we do not use under the Workspace server properties and applied patch Set Exception (PSE): 13327628 which addressed the following perfomance issues:
• 12913216 – Intermittent login error is observed while attempting to log into EPM System Workspace. Workspace displays the error message “You must supply a valid User Name and Password to log onto the system.” However, user can log in by clicking OK.
• 13341789 – Poor login performance (delay of 3-5 minutes) is observed at the first user login if Workspace web application has been inactive for an hour. Subsequent login performance is not impacted.
• 13388864 – In deployments where a firewall is configured to time out idle applications (for example, after 30 minutes) users can login once, but subsequent login times out.
In Shared Services we have also set Evict Interval and Allowed Idle Connection Time to 5 mins.
Is there anything else we could try to improve performance?
Thanks for your help.
Regards
Seb

If you already have deactivated the non used services from WS, it's weird. As I can see you may be using an external directory for authenticating, check on these.
* have you checked the response time from the external directory... sometimes for example in Active directory the user hierarchy is too complex to navigate on it. you can use an LDAP tester to see
* Are you using SSL? if yes, try wtihout SSL
* For workspace Start the non used services, and activate back the services in the WS to see if there it improves with all the apps up ( this will help you to narrow the debugging)
* go directly to java based servers, for instance in the shared services server go directly to the port 28080 for interop, instead of going by http server and check if you can login quick or not. This will help you also to isolate the issue (if it's related or not to Workspace).
Hope this help u to narrow your search

  • Performance issues - Log file parallel write

    Hi there,
    Since a few months I have big performance issues with my Oracle 11.2.0.1.0.
    If I look in the Enterprise manager (in blocking sessions) I see al lot of "log file paralles writes" and a lot of "log file sync" .
    We have configured an active data guard environment and are using ASM.
    We are not stressing out the database with heavy queries or commits or something, but sometimes during the day this happens on non specific times...
    We've investigated everything (performance to SAN / heavy queries / oracle problems etc etc) and we really don't know what to do anymore so i thought.. let's try a post on the Forum.....
    Perhaps someone had similar things?
    Thanks,
    BR

    Redo log file switch has good impact on the performance of the database. Frequent log switches may lead to the slowness of the database . Oracle documents suggests to resize the redolog files so that log switches happen more like every 15-30 min (roughly depending on the architecture and recovery requirements).
    AS i check the alertlog file and find that the log are switchinh very fequent which is one of the reason that you are getting checkpoint  not complete message . i have face this issue many times and i generally increase the size of the logfile and set the archive_lag_time parameter as i have suggested above . If you further want to go root cause and more details then above guys will help you more because i don't have much experience in database tunning . If you looking for aworkarounf then you must go through it .
    Good Luck

  • How to restrict logging on portal (Performance issue)

    Hi guys,
    does anyone know how to restrict logging of the portal? Even though I made a change on Visual Administrator -> Services -> Log Configurator setting ALL categories to severity = 'Error', I keep getting 'Info' severity traces logged in defaultTrace.trc (viewed by Logg Viewer). Which in practise means tons of logged trace information! I think this might be one of the reasons we have been experiencing performance issues lately.
    Does anyone know how to restrict this logging?
    Any help greatly appreciated!
    Cheers,
    Frank

    Hi,
    I would not only set the severity of categories to 'Error' but also locations to 'Error'.
    A log controller - can be a "category" or a "location".     Categories are used for "logging" and represent problem areas such as network, database, security, user interface, etc. Identified by a slash-separated ('/') path of names, prefixed with an additional slash.     Locations are used for "tracing" and correspond to places in the development components. Identified by a dot-separated ('.') path of names, which is often the name of the respective java package.

  • Performance issues related to logging (ForceSingleTraceFile option)

    Dear SDN members,
    I have a question about logging.
    I like to place my logs/traces for every application in different log files. By doing this you have to set the ForceSingleTraceFile option to NO (in the config tool).
    But in a presentation of SAP, named SAP Web Application Server 6.40; SAP Logging and Tracing API, is stated:
    - All traces by default go to the default trace file.
         - Good for performance
              - On production systems, this is a must!!!
    - Hard to find your trace messages
    - Solution: Configure development systems to pipe traces and logs for applications to their own specific trace file
    But I want the logs/traces also by our customers (production systems) in separate files. So my question is:
    What are the performance issues we face, if we turn the ForceSingleTraceFile option to NO by our customers?
    and
    If we turn the ForceSingleTraceFile to NO will the logs/traces of the SAP applications also go to different files? If so, then I can imagine that it will be difficult to find the logs of the different SAP applications.
    I hope that someone can clarify the working of the ForceSingleTraceFile setting.
    Kind regards,
    Marinus Geuze

    Dear Marinus,
    The performance issues with extensive logging are related to high memory usage (for concatenation/generation of the messages which are written to the log files) and as result increased garbare collection frequency, as well as high disk I/O and CPU overhead for the actual logging.
    Writing to same trace file, if logging is extensive can become a bottleneck.
    Anyway it is not related to if you should write the logs to the default trace of a standard location. I believe that the recommendation in the documentation is just about using the standard logging APIs of the SAP Java Server, because they are well optimized.
    Best regards,
    Sylvia

  • Performance issue of Security Audit log

    Hello,
              My client would like to activate the Security Audit log on his system. However he will like to know whether there could be any performance issue when activating it. Since I do not have any prior experience, can you please give me your general feedback on this subject. Have any of you experience performance issue when implementing security audit log and what can be done to minimize its effect?

    Hai,
    Activating Security Audit logs will not affect the performance of your SAP system. Since SAP Systems maintain their audit logs on a daily basis. The system does not delete or overwrite audit files from previous days; it keeps them until you manually delete them. Due to the amount of information that may accumulate, you should archive these files on a regular basis and delete the originals from the application server. This is the only thing you really need to take care since they might fill up the disk space if you dont archive or delete them on regular basis. Also since the data is very sensitive you should take extra care to protect the data.
    Please follow the below links for more details.....

  • Workspace login performance issues

    Hi folks,
    Thousand of users are using my fm application and they are hitting servers by smart view,workspace..once it's reach peak stage my server was getting hung and we were impliment no.of performnce tunning ( Vertical clustering,cahing,compression,hfm performcne tunning,reg setting )..we appiled performnce tunning all possible ways ..still we are facing performance issues..
    we are using 11.1.1.3 version..can anybody suggest me whta i need to do apart above changes..

    Hi Denis,
    To add on to the query, Basis have applied patch around two days back. As the thread you specified, member who was seeking the solution has not mentioned if the notes helped him finally. I think increasing the memory cache size might help. Also, the time taken to load the home page is irrespective of the load on the server, it takes same amount of time at off peak hours.

I have over 100 SOA Process running plus some BPM Process but BMP Workspace application is running too slow as have customized tasks forms. But the same works a bit better in other instance which is non-clustered. Any idea what can be done on the server level to get around the performance issues. So far have modified Audit Levels and reduced soa-infra bpm log have the following settings in setDomainEnv.sh for USER_MEM_ARGS=-Xms2000m -Xmx6000m -XX:PermSize=1000m
    But not help. Any idea what else to look into to get around these bpm performance issues. Here is what I have in setSOADomainEnv.sh

    After changing JVM settigns for soa cluster it's a bit better but still slow so wondering what other tweaks can be done on the JVM side. Here is what is for the SOA Cluster
    USER_MEM_ARGS="-server -Xms12928m -Xmx12928m -XX:PermSize=3072m -Xmn3232m -XX:+SXTElimination -XX:+UseParallelGC -XX:+UseParNewGC -XX:+ExplicitGCInvokesConcurrent -XX:-TraceClassLoading -XX:-TraceClassUnloading"
    We are running multiple instances on the same boxes and the total RAM on the machine is 95 GB on each box which is being shared across 4 cluster environments. For now other 3 cluster environments have the SOA Cluster JVM setting as
    USER_MEM_ARGS="-server -Xms4096m -Xmx4096m -XX:PermSize=1024m -Xmn1152m -XX:+SXTElimination -XX:+UseParallelGC -XX:+UseParNewGC -XX:+ExplicitGCInvokesConcurrent -XX:-TraceClassLoading -XX:-TraceClassUnloading"
    Any help on what else I can tweak or set in JVM to get a better performance.
    Thanks

  • Performance issue if lots of LOVs

    Hi,
    we have htmldb 1.5 installed in which we have several workspaces. One of the workspaces hosts several (about 20 ) applications. One of the applications has 40-50 LOVs. If I log into the workspace with ADMIN user and navigate to the Builder and choose the application which has lots of LOVs and try to click the LOVs tab it first hangs for ages and finally errors with page not found. This warning appears into the apache error_log:
    mod_plsql: Long running URL [pls/grp/f] timed out
    Can you please advice on any steps we could do to improve performance on LOV admin page. Overall performance with other applications and htmldb in general is fine. We only have issue with this one application which has large number of LOVs. Can you also advice if it is possible to remove LOVs by removing them directly from the htmldb tables as we are not able to remove through htmldb website.
    thanks!
    Nina

    Hi,
    thanks for looking into this thread!
    This issue was caused by too small buffer cache in the database.
    Db_cache_size was set to bigger value and few other parameters
    adjusted. This fixed the issue with the LOVs screen.
    thanks,
    Nina

  • Report performance Issue in BI Answers

    Hi All,
    We have a performance issues with reports. Report is running more than 10 mins. we took query from the session log and ran it in database, at that time it took not more than 2 mins. We have verified proper indexes on the where clause columns.
    Could any once suggest to improve the performance in BI answers?
    Thanks in advance,

    I hope you dont have many case statements and complex calculations that you do in the Answers.
    Next thing you need to monitor is how many rows of data that you are trying to retrieve from the query. If the volume is huge then it takes time to do the formatting on the Answers as you are going to dump huge volumes of data. Database(like teradata) returns initially like 1-2000 records if you hit show all records then even db is gonna fair amount of time if you are dumping many records
    hope it helps
    thanks

    I have other RAID installed, but not relevant for the present post...
    PSU
    Cosair 1000 Watts
    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).
    (picture 6)
    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.

    Subject: Re: Case 59063: performance issues w/ C TLIB and Forte 3M
    Hello,
    I just want to reiterate that we are very committed to working on
    this issue, and that our goal is to find out the root of the problem. But
    first I'd like to narrow down the avenues by process of elimination.
    Open Cursor is something that is commonly used in today's RDBMS. I
    know that you must test your query in ISQL using some kind of execute
    immediate, but Sybase should be able to handle an open cursor. I was
    wondering if your Sybase expert commented on the fact that the server is
    not responding to commonly used command like 'open cursor'. According to
    our developer, we are merely following the API from Sybase, and open cursor
    is not something that particularly slows down a query for several minutes
    (except maybe the very first time). The logs show that Forte is waiting for
    a status from the DB server. Actually, using prepared statements and open
    cursor ends up being more efficient in the long run.
    Some questions:
    1) Have you tried to do a prepared statement with open cursor in your ISQL
    session? If so, did it have the same slowness?
    2) How big is the table you are querying? How many rows are there? How many
    are returned?
    3) When there is a hang in Forte, is there disk-spinning or CPU usage in
    the database server side? On the Forte side? Absolutely no activity at all?
    We actually have a Sybase set-up here, and if you wish, we could test out
    your database and Forte PEX here. Since your queries seems to be running
    off of only one table, this might be the best option, as we could look at
    everything here, in house. To do this:
    a) BCP out the data into a flat file. (character format to make it portable)
    b) we need a script to create the table and indexes.
    c) the Forte PEX file of the app to test this out.
    d) the SQL staement that you issue in ISQL for comparison.
    If the situation warrants, we can give a concrete example of
    possible errors/bugs to a developer. Dial-in is still an option, but to be
    able to look at the TOOL code, database setup, etc. without the limitations
    of dial-up may be faster and more efficient. Please let me know if you can
    provide this, as well as the answers to the above questions, or if you have
    any questions.

    We did that trick already.
    When it is hanging, I can see what is doing.
    It is doing OPEN CURSOR. But not clear the exact statement of the cursor
    it is trying to open.
    When we run the query directly to Sybase, not using Forte, it is clearly
    not opening any cursor.
    And running it directly to Sybase many times, the response is always
    consistently fast.
    It is just when the query runs from Forte to Sybase, it opens a cursor.
    But again, in the Forte code, Alex is not using any cursor.
    In trying to capture the query,we even tried to audit any statementcoming
    to Sybase. Same thing, just open cursor. No cursor declaration anywhere.==============================================

    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 Homesharing?

    I have a Time Capsule as the base station for my wireless network, then 2 Airport Express setup to extend the network around the house, an iMac i7 as the main iTunes Library and couple of iPads, and a couple of Apple TVs. Everything has the latest software, but I have several performance issues with Home sharing. I've done several tests making sure nothing is taking additional bandwidth, so here are the list of issues:
    1) With nothing else running, trying playing a movie via home sharing in an iPad 2 which is located on my iMac, it stops and I have to keep pressing the play button over and over again. I typically see that the iPad tries to download part of the movie first and then starts playing so that it deals with the bandwidth, but in many cases it doesn't.
    2) When trying to play any iTunes content (movies, music, photos, etc) from my Apple TV I can see my computer library, but when I go in on any of the menus, it says there's no content. I have to reboot the Apple TV and then problem fixed. I's just annoying that I have to reboot.
    3) When watching a Netflix movie on my iPad and with Airplay I send the sound to some speakers via Airplay through an Airport Express. At time I lose the connection to the speakers.
    I've complained about Wifi's instability, but here I tried to keep everything with Apples products to avoid any compatibility issues and stay within N wireless technology, which I understood it was much more stable.
    Has anyone some suggestions?

    Hi,
    you should analyze the db after you have loaded the tables.
    Do you use sequences to generate PKs? Do you have a lot of indexex and/or triggers on the tables?
    If yes:
    make sure your sequence caches (alter sequence s cache 10000)
    Drop all unneeded indexes while loading and disable trigger if possible.
    How big is your Redo Log Buffer? When loading a large amount of data it may be an option to enlarge this buffer.
    Do you have more then one DBWR Process? Writing parallel can speed up things when a checkpoint is needed.
    Is it possible using a direct load? Or do you already direct load?

  • Performance issues with the Vouchers index build in SES

    Hi All,
    We are currently performing an upgrade for: PS FSCM 9.1 to PS FSCM 9.2.
    As a part of the upgrade, Client wants Oracle SES to be deployed for some modules including, Purchasing, Payables (Vouchers)
    We are facing severe performance issues with the Vouchers index build. (Volume of data = approx. 8.5 million rows of data)
    The index creation process runs for over 5 days.
    Can you please share any information or issues that you may have faced on your project and how they were addressed?

    Check the following logs for errors:
    1.  The message log from the process scheduler
    2.  search_server1-diagnostic.log  in /search_server1/logs directory
    If the build is getting stuck while crawling then we typically have to increase the Java Heap size for the Weblogic instance for SES>

  • Performance issues with version enable partitioned tables?

    Hi all,
    Are there any known performance issues with version enable partitioned tables?
    I’ve been doing some performance testes with a large version enable partitioned table and it seems that OCB optimiser is choosing very expensive plans during merge operations.
    Tanks in advance,

    Hello Vitor,
    There are currently no known issues with version enabled tables that are partitioned. The merge operation may need to access all of the partitions of a table depending on the data that needs to be moved/copied from the child to the parent. This is the reason for the 'Partition Range All' step in the plan that you provided. The majority of the remaining steps are due to the hints that have been added, since this plan has provided the best performance for us in the past for this particular statement. If this is not the case for you, and you feel that another plan would yield better performance, then please let me know and I will take a look at it.
    One suggestion would be to make sure that the table was been recently analyzed so that the optimizer has the most current data about the table.
    Performance issues are very hard to fix without a reproducible test case, so it may be advisable to file a TAR if you continue to have significant performance issues with the mergeWorkspace operation.
    Thank You,
    Ben
