Performance and Usability Problems-Aperture 3.1.3 and 10.7.1

Late 2009 iMac
Quad Core i7
8 GB RAM
512 ATI GPU
Nik Software Complete Collection Plugins—all updated
I’m guessing this is due to memory leaks, but Aperture is crippled with 10.7.1. On my great iMac, Aperture now runs like it did when I ran Aperture 2 on a 2004 PowerBook G4.
With Snow Leopard, I had none of these issues.
With Aperture idle, it uses up to 2 GB real memory and 3 GB virtual memory. With it idle, it generates MBs of page outs and swap used. If I start to use it for adjustments, even minor ones, page outs and swap used increase dramatically. For example, last night after editing and adjusting a project of images, page outs were just under 5 GB. I’ve reverted to the old habit of rebooting to clear page outs and swaps. Last time I had to do this was with the 2004 PowerBook.
While actually using Aperture for edits and adjustments, response to almost any input is slow, with conspicuous delays. Even checking and unchecking an adjustment brick causes a considerable delay between the click and when the change is visible.
Again, with Snow Leopard, Aperture was a bullet with current configuration. I just ordered 8 more GBs of RAM in hopes that this will help until Apple fixes Aperture.
Anyone else having such considerable performance issues with Aperture 3.1.3 and 10.7.1?
Thanks

John-
Actually I do think it is about individual setups. The kinds of complaints expressed in this thread have been going on literally for decades.
Starting with early-days Photoshop then later Aperture I have observed the challenges of heavy graphics apps with hardware/RAM/OSs/app versions. We have always been able to reproduce poor performance, because apps/OSs generally do evolve to be more demanding.
IMO our goal is to help individual setups tweak to achieve non-poor performance while we wait for stronger hardware, or an OS improvement, or an app improvement, or money to buy more RAM, or whatever. IMO it really is an ongoing individual-setup (e.g. last year I was running a 2006 C2D MBP with a max of 3 GB RAM requiring constant tweaking) issue.
Today I run Aperture under 10.6.8 on a 2011 MBP with SSD and 8 GB RAM and it rocks. I would consider 10.6.8 to be one of the tweaks that folks might do if all the other tweaks (like add RAM and run 32-bit) fail to achieve non-poor performance.

Review after 1 Month: Usability, Performance, and still...Streaming Issues...

After cruising around this board and others, I’m both very pleased with my Droid X and disappointed at the same time. I have an iPhone and a Droid X because I own a company that develops software for both platforms. Note that I have not “rooted” my phone.
I’m pleased that there are lots of apps and that Verizon has done a good job of putting in some stock apps that are useful (docking, clocks, widgets).
What I’m displeased with is performance and usability. Here are my chief concerns:
There are times that the screen delay in contacts is five seconds. I have about 650 contacts.
After having a Blackberry for years, I miss not being able to just start typing a phone number and bring up a list of likely names.
The iPhone has search integrated at the top of the screen. It saves one keystroke and one screen refresh.
Dialing an existing number requires two or three more steps than most phones. Short cuts still require two steps. The people short cuts are not very manageable.
I would like to reassign the search button from the home screen to search my contacts. I’m not quite into searching the web from the home screen. It’s my contacts I need.
I de-installed literally everything that keeps running that I know I don’t need or I do frequent force stops (like Facebook and Skype). Even though I’m on a data plan, I don’t want to use bandwidth and I don’t want these apps tracking my entire existence.
I too agree with everyone’s sentiments that not being able to de-install products like Amazon, Skype, etc are not in keeping with the concept of “Open” platform. Let the user decide. Don’t let your marketing agenda get in the way of people being happy with their products.
I have no desire to purchase an app that fixes a problem...ala short cuts, screen savers, etc.
I truly wish Verizon would fix streaming soon. I built an app that runs on every other Android 2.2 device except the Droids. Do you realize how frustrating it is to know the phone you own won’t run the apps you built? LOL!
Best Wishes – I hope this phones do well!!!

You can do this, just open Phone Dialer on contacts tab and then press menu button for 3 seconds and keyboard shows and all you have to do is type name.
The iPhone has search integrated at the top of the screen. It saves one keystroke and one screen refresh.
Android has easier way, just press search button 3 Second (Far Right) and say "Call NAME" and phone dials or shows contact info.
Dialing an existing number requires two or three more steps than most phones. Short cuts still require two steps. The people short cuts are not very manageable.
When searching for number all you have to do in press green phone icon to instant call..
I would like to reassign the search button from the home screen to search my contacts. I’m not quite into searching the web from the home screen. It’s my contacts I need.
The voice command app will open contact by just press search button for 3 second and say name to search contacts.

What problem are you having with streaming? I use iHeartRadio for streaming radio stations from many citys without issues.

Performance and Stability Problem with PE9

I just upgraded my computer to a Core i5 with 8G of memory and everything is running much faster. But my NEW PE9 just run very slow. Some of the simple tasks take 10-30 second to complete. Even Windows 7 will often come out to ask if I want to wait for PE9 to wake up or kill the process. When I want to change the size of a video clip, it just doesn't work at all due to performance. It will take PE9 20-30 seconds to resize the video clip. Without some realtime feedback of the size, it is impossible to do the resizing and this is a very fundamental operation. PE9 often crash or seize up as well, I didn't have any of these problem with PE3.0. I upgraded to PE9 simply because my PE3.0 for WIndows XP is not comletely compatible with Windows 7 (some of the text displace does not show up).
Do anyone else have issue with performance and stability?

Performance with repaint problem

Hi,
I have a performance and repaint problem.
My problem is than I have a layer pane with about 500 JScrollPane, each JScrollPane has a JLabel, and each JLabel has an Icon. I can have to maintain this hierarchy.
I have a thread that makes the icon change from a color state to a grey state; in fact it makes them all blink.
My problem is that is takes 50% of the CPU when the blink thread is running. As well, they do not all blink at the same time. The thread changes the icon color and calls a repaint. They seem to repaint independently.
What I would like is to collapse the paint calls into one without having to call repaint on the whole JFrame which does solve my problem but it is a hack.
Swing should collapse all the repaints into one call to the parent but I think because of the JScrollPanes it is not. Can anyone shed any light into why it does not paint all in one call instead of 500 repaint calls.
Thanks,
Pat

Well, I'd change the design first, but if you must play around with paint() then you can try using this setIgnoreRepaint(true) in the Component class.
You could do the grouping yourself and then when you really want things repainted, flag all your components again with setIgnoreRepaint(false), and then call revlaidate() to the parent, and it should repaint everything at once. That is what's I'd try, anyway.

Performance and Sprite objects

I've written an application in Flex 2 that consists of
several accordions containing custom canvas objects, and it is
having performance problems.
I'm running the application within IE 6.0 under Windows 2000.
The application loads an XML file and uses the data to create
custom Sprite objects in the canvases. Each Sprite consists of two
swf images that are loaded using the Loader class, a small
rectangle created by using the Sprite graphics property, and a text
label. In addition, each Sprite is connected to one or more other
Sprites by a line drawn using the Sprite's graphics property. The
Sprites have the capability for being dragged, and for being
highlighted when clicked.
My problem is performance; these Sprites perform slower than
a similiar program that I wrote in ActionScript 2.0. From what I
understand, Flex 2.0, ActionScript 3.0, Flash 9, and the new Sprite
class are supposed to deliver greatly improved performance, but my
new application seems worse than the old one under Flash 7 using
MovieClips. The more Sprites on the screen, the worse the
performance, and the lines seem to contribute to the degradation.
There is way too much code involved to include in this
message, so I'm looking for general info. Is there some basic point
I am missing?
The performance is also degraded when triggering instances of
the Menu and Popup classes. When running the Task Manager during
the application, I've noticed that both Memory Usage and GDI
objects increase whenever I display a Menu or Popup. Both Memory
Usage and GDI objects go up and down, but there is a steady
increase in both metrics as I continue to use Menus and Popups. As
far as I can tell, I am disposing of both types of objects
properly, but it appears that their allocation is remaining in
memory.

SQL Performance and Security

Help needed here please. I am new to this concept and i am working on a tutorial based on SQL performance and security. I have worked my head round this but now i am stuck.
Here is the questions:
1. Analyse possible performance problems, and suggest solutions for each of the following transactions against the database
a) A manager of a project needs to inspect total planned and actual hours spent on a project broken down by activity.
e.g
Project: xxxxxxxxxxxxxx
Activity Code          planned     actual (to date)
     1          20          25
     2          30          30
     3          40          24
Total               300          200
Note that actual time spent on an activity must be calculated from the WORK UNIT table.
b)On several lists (e.g. list or combo boxes) in the on-line system it is necessary to identify completed, current, or future projects.
2. Security: Justify and implement solutions at the server that meet the following security requirements
(i)Only members of the Corporate Strategy Department (which is an organisation unit) should be able to enter, update and delete data in the project table. All users should be able to read this information.
(ii)Employees should only be able to read information from the project table (excluding the budget) for projects they are assigned to.
(iii)Only the manager of a project should be able to update (insert, update, delete) any non-key information in the project table relating to that project.
Here is the project tables

I have the tables containing ouins and the rest. email me on [email protected] if you want to have a look at the tables.

Answer to your 2nd question is easy. Create database roles for the various groups of people who are allowed to access or perform various DML actions.
The assign the various users to these groups. The users will be restricted to what the roles are restricted to.
Look up roles if you are not familiar with it.

Can anybody recommend useful performance and tuning books. I plan to take the 12c perf tune beta on March 21st

Can anybody recommend any useful performance and tuning books.
I should probably limit my search to 11g or higher.
I am starting to prep for the 12c perf and tuning beta I have scheduled on March 21st.
Thanks Roger

Hi,
I will review your review.
I do see this Oracle 12c book at Amazon written over a year ago.
Its not a certificaiton book.
I also did take the course at Oracle for 11g performance and tuning.

Newspaper layouts cause major usability problems for your website

Think about what happens if a [Web Development|http://www.intellixmedia.com/web-development.htm] page is laid out in a newspaper-type multiple column format. How would visitors read that page? There will be this thin strip of text going down the page. To read it, they will have to scroll down with the browser to read that narrow strip. When they reach the bottom, they will have to scroll upwards again to find the next column to continue reading that same story. And so on. Back and forth, and up and down. In the meantime the rest of the space that they have in their huge monitor is wasted - they cannot use it to speed up their reading because at any one time, only one narrow column is relevant. The frustration and irritation caused by that kind of page will probably rival the annoyance caused by the webmaster mistakes listed in my satirical Seven Ways to Annoy Visitors to Your Website. In reality though, many visitors to such a website probably won't even bother to read the page. Why suffer the punishment when the competition is just a click away? (Bear with me in this section. It may not look relevant to the main topic, but I want to try to address one of the root causes of low-usability sites as a site with a newspaper layout would have been.) Many new web designers want their website to look unique. They want their site to look special and memorable. As such, they have a tendency to come up with all sorts of interesting things to do with their site, including this newspaper layout idea, so that it does not look like every other site on the Internet. Unfortunately, in so doing, as discussed before in my article on Appearance, Usability and Search Engine Visibility in Web Design, they may sometimes inadvertently create websites that cause usability problems as well as search engine indexing issues. Recall the (not so) early days of home desktop computing, when many people used an operating system called MS-DOS. Contrary to what you may think, not all programs that ran on DOS were command-line programs. There were full-screen or windowed programs like the ones you see on Windows and the Mac today. However, the task of learning to use new programs on DOS was not as easy as it is to use a new program on modern operating systems. Every program had their own way of doing things. For example, to save a file, different programs had different keystrokes and menus to accomplish the same task. With modern operating systems, companies like Microsoft and Apple have clearly-defined "Human Inteface Guidelines" for programmers to follow. As a result, the interface of just about every program on your computer is fairly similar. For example, to save a file in Windows, no matter what program you are using, you can simply use the "File" menu and the "Save" item on that menu. Or hit Ctrl+S. Or click the icon that looks like a floppy disk on the toolbar. The standardisation of the interface means that anyone who has learnt how to use one program will also know how to use another. You no longer have to read the manual. After installing a new program, most people can simply grope around and still be able to accomplish their task.
Web design is pretty much the same way. Although there is no overarching organisation to give a user interface guideline to specify that websites are to work a certain way, there are millions (or more) of websites on the Internet that more or less behave the same manner. By their existence and similarity alone, these existing websites have established a de facto standard. Users who know how to navigate a site with one of those standard design styles will also know how to navigate other sites with the same way of doing things. In other words, you don't have to be a web guru or a usability master to create a usable website any more. Just use the trick of following the standard pattern used by other sites - a one, two or three column website with navigation menus in the usual places (top, bottom, left or right), and the main content flowing downwards in the centre, links that work like normal links, and so on. (See my articles on usability if you want more information.) By making your site operate in a standard way, visitors will automatically find your site usable, because they've already learnt it from their past experience with other sites.

I have the same problem, as I can not log into my iCloud via Preference Pane since I changed my password which is verified correct. Keeps saying "Can not login at this time. Try to login again." Or just give the busy signal and eventually no connection.
I looked for the "Networkinterfaces.plist" entry but there is none. Any other potential solutions would be highly appreciated.
Apple refuses to help unless I pay $49 for their mistake.

Dreamweaver CS3 (9) maxed CPU slow performance and FTP issues.

Dreamweaver CS3 (9) maxed CPU slow performance and FTP
issues.
Never mind...I found it.
Of course I have all the firewall, worm, scanning, phishing
filtering, full time protect, and everything else turned off when I
am working on a remote/testing site however I found the Symantec
antivirus email scan being enabled (doesn't it just interact with
my email program?) was getting in the way of DW9 ftp operations,
causing some lagging that was putting DW9 into an unstable mode
during and immediately after (10 seconds) ftp operations.
The CPU still spikes to 99% during ftp functions but DW9
works even though it's likely taxed to the max but when I turn off
email scan DW9 returned to a functioning state during ftp and
remote file view. Whatever it takes huh?
PS: email scanning only never effected DW8.02
My System Info: properly configured (as in: everything works
or I fix it) Toshiba - XP pro SP2 – Pentium 4 - 2.3GHz

Thanks for the response. I managed to Google the 'nobody' account and found the explanation.
As you say, I assumed the 'syslogd' process had to do with system logs. I did check the console and couldn't find anything of particular interest in the logs.
I'll continue to monitor but if anyone has any further suggestions please post.
One thing that might also have an impact... my available drive space is now down to less than 5gb (runs anywhere between 1gb and 5gb free depending on what I'm running). I know this causes problems for Parallels as it keeps moaning at me, but would it cause any problems with OSX?
Thanks again,
Tom

Iphoto usability problems

Iphoto 7.01 has some glaring usability problems. These are the issues I've experienced.
If you have too many keywords, when you select the find by keyword option in the find box, the list of keywords goes off the screen, and there is no way to scroll through the list, rendering the search-by-keyword option useless.
Adding keywords in-line is cumbersome. If you want to tag a picture with the name John Smith, and you already have a keyword named John Apple, then iphoto automatically adds Apple after you type John. After a while this becomes maddening.
You can no longer move photos to the trash if you are in a smart album. This is very frustrating as it means you have to go into your main photo library and manually search for the photo you want to delete.
The search text box is buggy. When you click on the magnifying glass, the list that comes up is frequently in the wrong place.
In the Keyword Window (command+K) iphoto starts to alphabetize the keywords as you add them, and then after a while it starts putting them in random order.

I agree on your comments here.
I use Keywords alot, and the new way (without the ability to always have the keyword list up to use for sorting and assigning) is a pain in the butt from a usability perspective. Especially since the windowspace the keyword list sits in the prior version is just as free to be used by the keyword list as before.
Any keyword that is longer than a word or two (like "name 2005 birthday" and "name 2005 Mothersday") look exactly the same now ("name 200...") on the button list since the buttons are so scrunched (anyone with a long first or last name forget it) and I can't make them any wider. Same for assignment or selection. Had the keyword ordered to have your most common ones at the top and grouped together (like by family etc.), well that's gone. It's always alphabetical now.
Obviously alot of dev time went into this different way, but its a much less efficient and less usable a system. What a step backwards.

EXTREMELY SLOW XQUERY PERFORMANCE AND SLOW DOCUMENT INSERTS

EXTREMELY SLOW XQUERY PERFORMANCE AND SLOW DOCUMENT INSERTS.
Resolution History

### Complete Problem Description ###
A test file is being used to do inserts into a schemaless XML DB. The file is inserted and then links are made to 4
different collection folders under /public. The inserts are pretty slow (about
15 per second and the file is small)but the xquery doesn't even complete when
there are 500 documents to query against.
The same xquery has been tested on a competitors system and it has lightening fast performance there. I know it
should likewise be fast on Oracle, but I haven't been able to figure out what
is going on except that I suspect somehow a cartesian product is the result of
the query on Oracle.
### SQLXML, XQUERY, PL/SQL syntax used ###
Here is the key plsql code that calls the DBMS_XDB procedures:
CREATE OR REPLACE TYPE "XDB"."RESOURCEARRAY" AS VARRAY(500) OF VARCHAR2(256);
PROCEDURE AddOrReplaceResource(
resourceUri VARCHAR2,
resourceContents SYS.XMLTYPE,
public_collections in ResourceArray
) AS
b BOOLEAN;
privateResourceUri path_view.path%TYPE;
resource_exists EXCEPTION;
pragma exception_init(resource_exists,-31003);
BEGIN
/* Store the document in private folder */
privateResourceUri := GetPrivateResourceUri(resourceUri);
BEGIN
b := dbms_xdb.createResource(privateResourceUri, resourceContents);
EXCEPTION
WHEN resource_exists THEN
DELETE FROM resource_view WHERE equals_path(res, privateResourceUri)=1;
b := dbms_xdb.createResource(privateResourceUri, resourceContents);
END;
/* add a link in /public/<collection-name> for each collection passed in */
FOR i IN 1 .. public_collections.count LOOP
BEGIN
dbms_xdb.link(privateResourceUri,public_collections(i),resourceUri);
EXCEPTION
WHEN resource_exists THEN
dbms_xdb.deleteResource(concat(concat(public_collections(i),'/'),resourceUri));
dbms_xdb.link(privateResourceUri,public_collections(i),resourceUri);
END;
END LOOP;
COMMIT;
END;
FUNCTION GetPrivateResourceUri(
resourceUri VARCHAR2
) RETURN VARCHAR2 AS
BEGIN
return concat('/ems/docs/',REGEXP_SUBSTR(resourceUri,'[a-zA-z0-9.-]*$'));
END;
### Info for XML Querying ###
Here is the XQuery and a sample of the output follows:
declare namespace c2ns="urn:xmlns:NCC-C2IEDM";
for $cotEvent in collection("/public")/event
return
<cotEntity>
{$cotEvent}
{for $d in collection("/public")/c2ns:OpContextMembership[c2ns:Entity/c2ns:EntityIdentifier
/c2ns:EntityId=xs:string($cotEvent/@uid)]
return
$d
</cotEntity>
Sample output:
<cotEntity><event how="m-r" opex="o-" version="2" uid="XXX541113454" type="a-h-G-" stale="2007-03-05T15:36:26.000Z"

Need the most performance and scalable way to "trigger" JavaEE application

Hi,
Need the most performance and scalable way to "trigger" JavaEE application code running on WLS from PLSQL code.
There are some thirdparty JavaEE application running on WLS that we need to invoke from PLSQL code. I have looked at couple of options:
Option 1)
Use oracle db callouts(http call etc.) but it seems the connection to WLS will not be maintained across database-sessions and so every call from different plsql database-session will make fresh TCP/IP connection. Usually fresh socket connection setup is expensive and can become a bottleneck.
Option 2)
Use AQ in the database from PLSQL and have a MDB in WLS to invoke the java code. The problem here is how do I simulate the Request/Reply pattern using the AQ API from PLSQL. The PLSQL code needs to wait until the JavaEE code completes as it needs some result back from JavaEE app. AQ also does not have true temporary queues so I am not sure how it will work with concurrent user/sessions.
Option 3)
Use Java in the database, we have tried this but for our usecase it is too expensive resource wise and is not meeting our performance needs.
Performance is the triggering mechanism is of highest interest to us.
Any suggestions/pointers is greatly appreciated.
Thanks,
Prantor

Perhaps you would benefit from viewing the problem differently.
In some/many/most cases the application server (WLS) invokes procedure residing in the DB server.
Place the control for the desired results in the application code running on the WLS.

The 15" Retina's will have better performance than any 13" Retina. Not only do the 15" machines have dedicated GPU's, but they also have quad-core processors, whereas the 13" Retina's only have dual-core processors.

BW Back end
Some Tips -
1)Identify long-running extraction processes on the source system. Extraction processes are performed by several extraction jobs running on the source system. The run-time of these jobs affects the performance. Use transaction code SM37 Background Processing Job Management to analyze the run-times of these jobs. If the run-time of data collection jobs lasts for several hours, schedule these jobs to run more frequently. This way, less data is written into update tables for each run and extraction performance increases.
2)Identify high run-times for ABAP code, especially for user exits. The quality of any custom ABAP programs used in data extraction affects the extraction performance. Use transaction code SE30 ABAP/4 Run-time Analysis and then run the analysis for the transaction code RSA3 Extractor Checker. The system then records the activities of the extraction program so you can review them to identify time-consuming activities. Eliminate those long-running activities or substitute them with alternative program logic.
3)Identify expensive SQL statements. If database run-time is high for extraction jobs, use transaction code ST05 Performance Trace. On this screen, select ALEREMOTE user and then select SQL trace to record the SQL statements. Identify the time-consuming sections from the results. If the data-selection times are high on a particular SQL statement, index the DataSource tables to increase the performance of selection (see no. 6 below). While using ST05, make sure that no other extraction job is running with ALEREMOTE user.
4)Balance loads by distributing processes onto different servers if possible. If your site uses more than one BW application server, distribute the extraction processes to different servers using transaction code SM59 Maintain RFC Destination. Load balancing is possible only if the extraction program allows the option
5)Set optimum parameters for data-packet size. Packet size affects the number of data requests to the database. Set the data-packet size to optimum values for an efficient data-extraction mechanism. To find the optimum value, start with a packet size in the range of 50,000 to 100,000 and gradually increase it. At some point, you will reach the threshold at which increasing packet size further does not provide any performance increase. To set the packet size, use transaction code SBIW BW IMG Menu on the source system. To set the data load parameters for flat-file uploads, use transaction code RSCUSTV6 in BW.
6)Build indexes on DataSource tables based on selection criteria. Indexing DataSource tables improves the extraction performance, because it reduces the read times of those tables.
7)Execute collection jobs in parallel. Like the Business Content extractors, generic extractors have a number of collection jobs to retrieve relevant data from DataSource tables. Scheduling these collection jobs to run in parallel reduces the total extraction time, and they can be scheduled via transaction code SM37 in the source system.
8). Break up your data selections for InfoPackages and schedule the portions to run in parallel. This parallel upload mechanism sends different portions of the data to BW at the same time, and as a result the total upload time is reduced. You can schedule InfoPackages in the Administrator Workbench.
You can upload data from a data target (InfoCube and ODS) to another data target within the BW system. While uploading, you can schedule more than one InfoPackage with different selection options in each one. For example, fiscal year or fiscal year period can be used as selection options. Avoid using parallel uploads for high volumes of data if hardware resources are constrained. Each InfoPacket uses one background process (if scheduled to run in the background) or dialog process (if scheduled to run online) of the application server, and too many processes could overwhelm a slow server.
9). Building secondary indexes on the tables for the selection fields optimizes these tables for reading, reducing extraction time. If your selection fields are not key fields on the table, primary indexes are not much of a help when accessing data. In this case it is better to create secondary indexes with selection fields on the associated table using ABAP Dictionary to improve better selection performance.
10)Analyze upload times to the PSA and identify long-running uploads. When you extract the data using PSA method, data is written into PSA tables in the BW system. If your data is on the order of tens of millions, consider partitioning these PSA tables for better performance, but pay attention to the partition sizes. Partitioning PSA tables improves data-load performance because it's faster to insert data into smaller database tables. Partitioning also provides increased performance for maintenance of PSA tables for example, you can delete a portion of data faster. You can set the size of each partition in the PSA parameters screen, in transaction code SPRO or RSCUSTV6, so that BW creates a new partition automatically when a threshold value is reached.
11)Debug any routines in the transfer and update rules and eliminate single selects from the routines. Using single selects in custom ABAP routines for selecting data from database tables reduces performance considerably. It is better to use buffers and array operations. When you use buffers or array operations, the system reads data from the database tables and stores it in the memory for manipulation, improving performance. If you do not use buffers or array operations, the whole reading process is performed on the database with many table accesses, and performance deteriorates. Also, extensive use of library transformations in the ABAP code reduces performance; since these transformations are not compiled in advance, they are carried out during run-time.
12)Before uploading a high volume of transaction data into InfoCubes, activate the number-range buffer for dimension IDs. The number-range buffer is a parameter that identifies the number of sequential dimension IDs stored in the memory. If you increase the number range before high-volume data upload, you reduce the number of reads from the dimension tables and hence increase the upload performance. Do not forget to set the number-range values back to their original values after the upload. Use transaction code SNRO to maintain the number range buffer values for InfoCubes.
13)Drop the indexes before uploading high-volume data into InfoCubes. Regenerate them after the upload. Indexes on InfoCubes are optimized for reading data from the InfoCubes. If the indexes exist during the upload, BW reads the indexes and tries to insert the records according to the indexes, resulting in poor upload performance. You can automate the dropping and regeneration of the indexes through InfoPackage scheduling. You can drop indexes in the Manage InfoCube screen in the Administrator Workbench.
14)IDoc (intermediate document) archiving improves the extraction and loading performance and can be applied on both BW and R/3 systems. In addition to IDoc archiving, data archiving is available for InfoCubes and ODS objects.
Hope it Helps
