Hi,
Please read this message in the [ABAP Performance and Tuning|DOI - I_OI_SPREADSHEET, poor performance when reading more than 9999 record; section and see if you have any advise.
Best Regards,

Hi,
I met this issue when I tried to write vaule to massive fields of excel range.
And I solve this issue by using CL_GUI_FRONTEND_SERVICES=>CLIPBOARD_EXPORT.
So, I think you may fix it in the same way.
1. Select range in by the I_OI_SPREADSHEET
2. Call method I_OI_DOCUMENT_PROXY->COPY_SELECTION
3. Call method CL_GUI_FRONTEND_SERVICES=>CLIPBOARD_IMPORT

Poor performance when dragging item within a list loaded with images - Flex 4

Hi,
I have a custom built List component that is using a TileLayout. I am using a custom itemRenderer to load images into this list from our server (in this test, 44 images rae loaded). I have enabled dragEnabled and dragMove so that I can move items around within the list. The problem comes when I start dragging an item. The dragging operation is very slow and clunky.
When I move the mouse to drag the item, the dropIndicator does not get refreshed for a few seconds and the movement feels like my PC is lagging pretty badly. I've also noticed that during this time my CPU usage is spiking up to around 25-40%. The funny part is I can scroll the list just fine without any lag at all, but the minute I drag the application starts to lag really bad. I do have some custom dragOver code that I used to override the dragOverHandler of the list control, but the problem persists even if I take that code out. I've tried with useVirtualLayout set to both true and false and neither setting made a difference.
Any ideas as to what could be causing the poor performance and/or how I can go abouts fixing it?
Thanks a lot in advance!

Ahh, good call about the Performance profiler. I'm pretty new to the profiling thing with Flex (haven't used Builder Pro before
the Flex 4 beta) so please forgive me
I found some interesting things running the performance profiler but I'm not sure I understand what to make of it all. I cleared the Performance Profile data when right before I loaded the images into the list. I then moved some images around and then captured the Profiling Data (If I understand Adobe correctly, this is the correct way to capture performance information for a set of actions).
What I found is there is a [mouseEvent] item that took 3101ms with 1 "Calls" (!!!!). When I drill down into that item to see the Method Statistics, I actually see three different Callees and no callers. The sum of the time it took the Callees to execute does not even come close to adding up to the 3101 ms (about 40ms). I'm not sure what I can make of those numbers, or if they are even meaningful. Any insight into these?
The only other items that stand out to me are [pre-render] which has 863ms (Cumulative Time) / 639ms (Self Time), [enterFrameEvent] which has 746ms / 6ms (?!), and [tincan] (what the heck is tincan?) which has times of 521ms for both Cumulative and Self.
Can anyone offer some insight into these numbers and maybe make some more suggestions for me? I apologize for my ignorance on these numbers - as I said, I'm new to the whole Flex profiling thing.
Many thanks in advance!
Edit: I just did another check, this time profiling only from the start of my drag to the end of my drop, and I still see [mouseEvent] taking almost 1000ms of Cumulative Time. However, when I double click that item to see the Method Statistics, no Callers or Callees are listed. What's causing this [mouseEvent] and how come it's taking so long?

Poor performance when accessing a MSAS 2008 cube via BI Server

I am having an issue with performance when accessing a MSAS 2008 cube via the BI Server.
I think it has to do with the way that the MDX is being generated.
Please could someone advise on any settings I could try or any known issues with the integration?
Thanks,

Hi Kim,
Sorry I can't help out, but, I'm curious how you got the AS 2008 drivers installed for use with OBIEE? I have an AS2008 environment, but, my OBIEE version only supports 2000 and 2005.
Thanks,

Poor performance when using kde desktop effect

Hey,
I'm having trouble when using kde effet (system settings -> desktop -> desktop effects).
I have a dual core E5200 3 ghz, 2 GB memory pc8500 and an HD4850 using fglrx driver, but I got incredible bad performance when using desktop effect and watching video, I can barely watch a 800x600 video in full screen mode without having bad performance, X getting up to 40% cpu usage.
Its really like my graphic card isnt handling the rendering stuff but 3D acceleration is working, I can play 3D game without problem so far (as long as the deskstop effect arent enabled cause the cpu have like a hard time handling both for recent game)
So I guess its some trouble with 2D acceleration or something like that, I read that some people had such issue, but I didnt figure a way to fix it.

Poor performance when multitasking on T510, Core i5, Windows 7 64, 4GB RAM, NVidia Optimus 512MB

I'm saddly disappointed with my new Lenovo performance and don't know what might be the cause.
I just got a new T510 with Core i5 processor, 4GB RAM and Windows 7 64. When I run a couple of programs, like Photoshop, a Virtualbox (850 MB of RAM allocated), Google Chrome with a couple of tabs I get stuck.
It seems that 4GB of memory is not enough for the work I did on a 2GB machine a week ago.
The computer's response time is a couple of seconds for window switching. New programs start counting in minutes. RAM consumption reaches 98%, even though no single program is listed to consume more than a 150MB in either Task Manager or Resource monitor. Aero effects work cool, though, there's no sloppiness in the graphical layer of the system.
Even now, after having Virtualbox killed, remaining processes take up 89% of RAM memory in Resource manager.
I'm working on AC power supply with "Perfomance" power setting, but I can hardly call it a performance.
This is ridiculous, it was supposed to be a fast multitasking machine and it turns out to be a load of junk. I used to work on 2GB, 1.6GHz Celeron with Intel GMA processor, had Ubuntu host and Windows XP guest with 750MB RAM allocated plus a couple of programming tools running and never had such issues _on regular basis_.
I'm considering running a Ubuntu on this machine because I simply can't work this way on Windows 7... I can't even kill a process easily because it takes ages to End a process.
A friend of mine is running similar setup on a T410 machine with slower CPU and poorer graphics and he says this is really strange, because he never had such problems. My PC is new, 4 days since arrival, his is like 2-months old.
Has anyone experienced similar problem? What might be the cause?
At this point I have Chrome with ~10 tabs, empty Firefox, empty Photoshop, Pidgin, and 3 explorer windows running, Adobe Reader with 1 document and Sticky Notes. RAM consumption is 3495MB in use (yeah right), 276MB standby and 113 free.
What's wrong here?!
Please see the screenshot attached:
http://img715.imageshack.us/i/captureybh.png/
Solved!
Go to Solution.

Well, the issue is solved. After removing bundled Norton Internet Security suite it runs like gold-plated.
I'll get another anti-virus software, then.
Now, even with the Virtualbox running, I still have like 2GB free RAM. And no lags, no slow-downs. Woohoo.
**bleep** you Norton!

Decreasing performance when executing consecutive XQuery Update operations

hello,
I am writing an application in java using Berkeley DB XML (2.5.16). I have to run a test over the application, in which a lot of XQuery Update operations have to be executed. All update operations are insert statements. In the beginning the test works fine. However, as the number of updates increases (over 1000 XQuery Updates), there is also a great increase in time of execution. How can I enhance the performance of updates?
Note that:
1) The environment configuration is the following:
EnvironmentConfig envConfig = new EnvironmentConfig();
envConfig.setAllowCreate(true);
envConfig.setInitializeCache(true);
envConfig.setCacheSize(512*1024*1024);
envConfig.setInitializeLocking(false);
envConfig.setInitializeLogging(false);
envConfig.setTransactional(false);
2) No transactions are used
3) The container is a node container
4) Auto-indexing is on (I need that)
5) The container includes only one xml of 2,5MB size.
6) In some insert statements 1000 nodes are to be inserted.
7) I am running windows vista on a 4GB Ram pc.
Thank you in advance,
theo

Hi Lucas,
Thanks a lot for your reply! However, I have a few more questions.
Given that the xml is about 2.5MB size, is it considered to be that big for Berkeley DB so it needs to be break down into smaller documents?
Also, after having executed ~4000 xquery update insert operations and doubled xml’s size, the performance it’s really getting worse… An insertion may even take 1.5 min, when for each of the first 3000 insertions only less than 0.5 sec is needed… Is there something I am missing in the configuration of Berkeley DB? If I set autoindexing off and try to maintain fewer indexes, is it possible to see significantly better performance? Till now I am just getting the following error when I set my indexes and try to execute consequent insertions over the same node:
Exception in thread "main" com.sleepycat.dbxml.XmlException: Error: Sequence does not match type item() - the sequence does not contain items [err:XUDY0027], <query>:1:1, errcode = QUERY_EVALUATION_ERROR+

Is anyone able to explain really poor performance when using 'If Exists'?

Hello all. We've recently had a performance spike when using the 'if exists' construct, which is a construct that we use through much of our code. The problem is, it appears illogical since if can be removed via a tiny modification that does
not change the core code.
I can demonstrate
This is the (simplified) format of the base original code. It's purpose is to identify when a column value has changed comparing to a main table and a complex view
select 1 from MainTable m
inner join ComplexView v on m.col2 = v.col2
where m.col3 <> v.col3
This is doing a table scan, however the table only has 17000 rows while the view only has 7000 rows. The sql executes in approximately 3 seconds.
However if we add the 'If Exists' construct around the original query, like such:
if exists (
select 1 from MainTable m
inner join ComplexView v on m.col2 = v.col2
where m.col3 <> v.col3
print 1
The sql now takes over 2 minutes to run. Note that the core sql is unchanged. All I have done is wrap it with 'If Exists'
I can't fathom why the if exists construct is taking so much longer, especially since the code code is unchanged, however more importantly I would like to understand why since we commonly use this type of syntax.
Any advice would be greatly appreciated

OK, that's interesting. Adding the top 1 clause greatly affects the performance (in a bad way).
The original query (as below) still runs in a few seconds.
select 1 from MainTable m
inner join ComplexView v on m.col2 = v.col2
where m.col3 <> v.col3
The 'Top 1' query (as below) takes almost 2 minutes however. It's exactly the same query, but with 'top 1' added to it.
select top 1 1 from MainTable m
inner join ComplexView v on m.col2 = v.col2
where m.col3 <> v.col3
I suspect that the top 1 is performing a very similar operation to the exists, in that it is 'supposed' to exit as soon as it finds a single row that satisfies it's results.
It's still not really any closer to making me understand what is causing the issue however.

Poor performance when running DBMS_STATS package

Hello,
I thought I would throw this issue out to the general population as I am stumped.
I have two identical schemas on two different severs. Database in 9.2.0.6 and for QAS and Production reasons the servers and database settings are identical.
I am running the DBMS_STATS.GATHER_SCHEMA_STATS package on both databases. On the QAS DB it takes roughly 1.5 hours while on the Production database it takes 8.0 hours.
Looking at the statspack analysis, the biggest thing to jump out at me is that the temporary tablespace is getting 4.6 Million I/O hits (reads) while the QAS is only getting a few thousand.
So .... this sort of indicates that something is going on in the PGA which could cause Oracle to use the TEMP tablespace. However when I look in the host performance (using Grid Control) the servers memory, file I/O, and CPU while high are not over 80%.
Has anyone else seen and issue like this? Any ideas where to look?
Thanks,
Chris

To the extent that you are gathering histograms on the data, Oracle potentially has to do a reasonable amount of sorting. If one machine has substantially more physical RAM, that presumably implies that it has more RAM available for the PGA, which would allow more sorts to happen in memory rather than on disk.
Depending on how you create a "refresh copy of production" and what parameters you are passing in to DBMS_STATS, it is also possible that the quality assurance database is gathering substantially more histograms than the production database (i.e. you refresh lower environments via export and import rather than doing an RMAN clone and tell Oracle to gather histograms on any columns that currently have histograms).

Performance when executing query on 9iAS Discoverer Plus 1.0.2.2

Hi, anybody knows when there's information about Discoverer Plus configuration (9iAS release 1) to get a good performance? Because, when I run queries, the response time is not good enough.
I have configured the pref.txt file based on the advises of "Oracle 9iAS Discoverer: Best Practices for Release 1.0.2.2 (Discoverer 4i Version 4.1.42x and later)" paper, but without the expected results. Does exist another document about that?
Thanks a lot in advance.

Hi,
I'm a Pablo´s partner, he is on vacation now and is very sorried about not answering this forum. In particular, we need documentation about the improvement of running Discoverer queries on 9iAS, may be through configurations on the web server.
We have tunned the queries on client/server, and they run on expected response times, do you know if there's a document "9iAS Discoverer Tunning"?, or something like that?
Thanks a lot in advance.

Poor performance when using skip-level hierarchies

Hi there,
currently we have big performance issues when drilling in a skip-level hierarchy (each drill takes around 10 seconds).
OBIEE is producing 4 physical SQL statements when drilling f.e. into the 4th level (for each level one SQL statement). The statements runs in parallel and are pretty fast (the database doesn't need more than 0,5 seconds to produce the result), but ... and here we have probably somewhere a problem ... putting all the 4 results together in OBIEE takes another 8 seconds.
This are not big datasets the database is returning - around 5-20 records for each select statement.
The question is: why does it take so long to put the data together on the server? Do we have to reconfigure some parameters to make it faster?
Please guide.
Regards,
Rafael

If you really and exclusively want to have "OBIEE can handle such queries" - i.e. not touch the database, then you had best put a clever caching strategy in place.
First angle of attack should be the database itself though. Best sit down with a data architect and/or your DBA to find the best setup possible physically and then when you've optimized that (with regard to the kind of queries emitted against it) you can move up to the OBIS. Always try t fix the issue as close to the source as possible.

BIBean poor performance when using Query.setSuppressRows()

Does anyone have experience in suppressing N/A cell values using BIBean? I was experimenting the use of Query.setSuppressRows(DataDirector.NA_SUPPRESSION). It does hide the rows that contains N/A values in a crosstab.
The problem is that the performance degrades significantly when I started drilling down the hierarchy. Without calling the method, I was able to drill into the pre-aggregated hierarchy in a few seconds. But with setSuppressRows(), it took almost 15 minutes to do the same drill.
Just for a comparison, I used DML to report on the same data that I wanted to drill into. With either 'zerorow' to yes or no, the data was fetched less than a second.
Thanks for any help.

At the moment we are hoping this will be fixed in a 10g database patch which is due early 2005. However, if you are using an Analytic Workspace then you could use OLAP DML to filter the zero and NA rows before they are returned to the query. I think this involves modifying the OLAP views that return the AW objects via SQL commands.
Hope this helps

[SOLVED] Older NVIDIAs - (quite poor) performance when watching movies

I'd like to ask what packages and configuration you use to achieve the best performance for NVIDIA GeForce FX 5200, mainly for watching movies. I've come to this observation:
Global parameters
NVIDIA GeForce FX 5200 (AGP 4x, 128 MB)
1680x1050, 60 Hz
Pentium 4 2.4 GHz, 1 GB RAM
SMPlayer 0.6.9 (SVN r3447)
Used video: 1280 x 720, 23.976 FPS, fullscreen
Windows XP (SP2):
Driver: 16. 5. 2008 (version 6.14.11.7519)
MPlayer SVN r30369
Output method: directx(fast)
Video: fluent
Ubuntu 11.04:
Driver: nvidia-173 (probably, Ubuntu is so confusing)
MPlayer 1.0rc4-4.5.2
Output method: xv
Video: fluent but often with a diagonal break
Arch Linux:
Driver: nouveau
MPlayer SVN r34426
Output method: xv
Video: goes to few FPS after a minute

I'm not an A/v guy, but I think you can encode stuff in different ways and that might make a difference, so just because I haven't had any problems with 720p doesn't mean you're doing something wrong, maybe you're viewing higher-quality material.
I don't get choppy video even when I'm maxing-out the cpu.
mplayer --framedrop -vfm ffmpeg -lavdopts lowres=1:fast:skiploopfilter=all
is the magic incantation I use to view some 720p stuff on my other PC which has just and old, unsupported integrated Intel card. I get "almost-fluent but often with a diagonal break" video.
Yes, this not 30fps 720p anymore, so I'm cheating ;P

Not really.

Poor Performance when using Question Pooling

I'm wondering if anyone else out there is experiencing
Captivate running very slow when using question pooling. We have
about 195 questions with some using screenshots in jpeg format.
By viewing the Windows Task Manager, CP is using anywhere
between 130 to 160 K worth of memory. What is going on here? It's
hammering the system pretty hard. It takes a large effort just to
reposition the screenshot or even move a distractor.
I'm running this on a 3.20GHz machine with 3GB of RAM.
Any Captivate Gurus out there care to tackle this one?
Help.

MtnBiker1966,
I have noticed the same problem. I only have 60 slides with
43 questions and the Question Pool appears to be a big drain on
performance. Changing the buttons from Continue to Go to next slide
helped a little, but performance still drags compared to not using
a question pool. I even tried reducing the number of question
pools, but that did not affect the performance any. The search
continues.
