Mac os x performance and impossible to increase size of jdev screen

After installing jdev in my wife mac osx laptop (i forgot my windows duo laptop and can't wait to see the new features in jdev !), i got the first jdev menu entry in the main menu bar after a few minutes (i was not sure i started it correctly) and the first dialog that ask for migration from a previous version a few more minutes later. May it would be better to display something before, just to show the programm started and that it is working ... a lot ... to initialize the system. Note the system is 4 year old and have only 256 mb memory ... but it is working ... even with jdev.
More important, it was not possible to increase the size of the jdev screen in that version. mac osx 10.4.9.

As far as the delay goes... believe it or not, the migration dialog that appears really is extremely early in our code. However, a little bit earlier than that, the splash screen ought to appear, which contains a progress bar. Are you seeing that?
It may be that Java startup on your machine is just generally slow. On my 2GHz Intel Core Duo iMac with 1GB of RAM, I see the splash screen within a second or two of clicking the JDeveloper icon in the dock. The main window takes about 30 seconds to appear.
Thanks,
Brian

Mac OS X Lion and Java7 + JavaFX2.1 performance issues

Currently I'm using the JavaFX 2.1 GA Build with Mac OS X Lion (10.7.3) on my MacBook Pro (2.33 GHz Intel Core 2 Duo, 4GB 667 MHz DDR2 SDRAM, ATI Radeon X1600 256 MB) an run into some performance and ui problems. The overall rendering framerate is arround ~30fps (which is normally 60fps on my desktop computer) and if I try to resize the main window the window starts to flicker and I get the following exception:

For JavaFX applications to take advantage of the new hardware acceleration pipeline provided by JavaFX, your system must feature one of a wide range of GPUs currently available in the market. Table 1 lists the graphics cards that have been tested with JavaFX. If your system does not support hardware acceleration, then JavaFX uses the Java2D software pipeline.
For Mac OS X, the following standard Apple hardware graphics chips provide the required support:
- Intel HD Graphics 3000 processor with 288MB of DDR3 SDRAM shared with main memory
- AMD Radeon HD 6630M graphics processor with 256MB of GDDR5 memoryYour graphics card is not on that list, so JavaFX is falling back to a software pipeline, which does not work that well for you. You may not be able to resolve some performance issues when using a software pipline. You can log an issue at http://javafx-jira.kenai.com to request the NullPointerException be fixed - as that should not occur in any case and is a bug.

Mac Mini Core Duo and 23" Cinema Display: video graphics performance

I know the Mac Mini Core Duo and the 23" Cinema Display are compatible but can anybody tell me if one can expect better graphics performance when using a 20" display or does it not make any difference?

Thanks Dan but maybe I didn't make myself clear. What I'm interested in is whether or not one can expect a noticeable difference in video graphics performance between a 20" Cinema Display and a 23" Cinema Display, when connected to a Mac Mini Core Duo.

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?

SPYWARE on my MAC?! pcturbopro and drivecleaner

For the last three days I have been getting pop-up messages when I surf the internet! (I have two Macs, and it is happening on both!)
One about DriveCleaner and one about PCTurboPro.
I checked it out, and they are both listed as Spyware, infecting PC computers.
My question: Do I have them on my Mac?! If so, how can I get rid of them?
All the help I could find and all the Antispyware programs are for PC only...
Thanks!

The posts here have not really answered the question. Why does the PCTurboPro trojan/malware/virus (whatever it is) seen to be infecting our Macs. Are they really doing any harm? what is we do get infected and passit on to a PC unknowingly coworker?
I have no clue to any of the above, but I wanted to document exactly what is happening to me and what I did to correct the issue (it is corrected for now).
On 8/20/07 I was using my MacBook 2GHz duo core with 1 GB 667 MHz DDR2 SDRAM. I had OS X 10.4.10 running and was using FireFox 2.0.0.6.
I was on Google news surfing around, using the "Apple Key + click pad" combo going to launch a new tab with the news story. I have no clue what site I clicked on because I was moving too quickly.
The entire FireFox window disappeared (minimized?, but I couldn;t restore it manually) and a Mac Style dialog box appeared (see http://www.deltaspark.net/transfer/pcturbo-popup.jpg) that said:
"The page at http://pcturbo.com says:
NOTICE: Your system is not optimized and your
computer peformance is not at the highest level.
Full system optimization will greatly increase your
computer's performance and prevent data loss.
Would you like to install PCTurboPro to potimize your
computer's performance now for free? (Recommended)
("Cancel" Button) ("OK" Button)"
I clicked cancel and the once disappeared browser window (with active tabs) reappeared. I ignored the entire thing and did not quit FireFox.
Then 10 minutes later it happened again. this time I took the screenshot (http://www.deltaspark.net/transfer/pcturbo-popup.jpg) and force quit FireFox.
I then launched FireFox, cleared my cache, history, cookies, etc. and for 2 days it has not happened again.
Anyone have ideas regarding this?

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

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

jcrosby wrote:The "individual setup" argument is an oversimplification. With relatively current hardware, I can reproduce very poor performance when running Aperture in Lion in either 32-bit or 63-bit mode (though the patterns change a bit), and so can many others.
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.

I need a clarification : Can I use EJBs instead of helper classes for better performance and less network traffic?

My application was designed based on MVC Architecture. But I made some changes to HMV base on my requirements. Servlet invoke helper classes, helper class uses EJBs to communicate with the database. Jsps also uses EJBs to backtrack the results.
I have two EJBs(Stateless), one Servlet, nearly 70 helperclasses, and nearly 800 jsps. Servlet acts as Controler and all database transactions done through EJBs only. Helper classes are having business logic. Based on the request relevant helper classed is invoked by the Servlet, and all database transactions are done through EJBs. Session scope is 'Page' only.
Now I am planning to use EJBs(for business logic) instead on Helper Classes. But before going to do that I need some clarification regarding Network traffic and for better usage of Container resources.
Please suggest me which method (is Helper classes or Using EJBs) is perferable
1) to get better performance and.
2) for less network traffic
3) for better container resource utilization
I thought if I use EJBs, then the network traffic will increase. Because every time it make a remote call to EJBs.
Please give detailed explanation.
thank you,
sudheer

Please suggest me which method (is Helper classes or Using EJBs) is perferable :
1) to get better performance
EJB's have quite a lot of overhead associated with them to support transactions and remoteability. A non-EJB helper class will almost always outperform an EJB. Often considerably. If you plan on making your 70 helper classes EJB's you should expect to see a dramatic decrease in maximum throughput.
2) for less network traffic
There should be no difference. Both architectures will probably make the exact same JDBC calls from the RDBMS's perspective. And since the EJB's and JSP's are co-located there won't be any other additional overhead there either. (You are co-locating your JSP's and EJB's, aren't you?)
3) for better container resource utilization
Again, the EJB version will consume a lot more container resources.

Specifically, the posts by Dunsany and valkyr did the trick. I booted in safe mode, uninstalled and deleted the Nvidia driver, disabled automatic driver installation, and restarted normally. I then manually downloaded and installed the previous Nvidia driver for my graphics card (which at the time of this writing was 335.23, rather than the latest which was 337.88), and everything is now bueno!
Two hiccoughs along the way: First, when I tried to uninstall the Nvidia driver the first time, when I restarted I got the login screen (which was a good sign), but it quickly went black again. I powered down, restarted in safe mode again, and repeated the uninstallation process, and it worked the second time. Second, when I started the manual install of the 335.23 driver, the computer played a sound similar to the one for disconnecting a USB device, and the screen went black. I'd seen a lot about trying to increase the brightness (though it hadn't worked up to this point; but if you haven't tried it yet, might as well); I tried it, and it worked! So far I'm back up and running. [/fingers crossed]

On windows XP or linux have a MAC adress Change function allow 00 mac adress and another normal mac adress range.On windows 8.1 all Mac changer program dont work.This 2,6,A,E on second adress are not vaild Mac adress. You simply can not use normal MAC
addresses on windows 8.1.When i connect the usb the Pc windows 8.1 recognizes the adapter but the default driver and the downloaded ralink driver the same problem.On windows xp the current driver works perfectly have (Local Mac Network Adress) funktion
and works with the 802.11b hot spot.I got the internet my PC and laptop too public HotSpots and another wifi HotSpots if wont work correctly i can not use neither the windows 7,8,8.1 or 10. Many users have expressed interest in the problem more forums.
The 3. problem im tested in virtualbox the windows 7 and 8.1 on 8.1 (on the blue wifi platform) not show correctly the signal strengh. On windows 7 show this correctly.The windows 7-8.1 Configure/advanced the advanced options on Ralink 3070 the default (windows
driver) somehow downgraded function is less than for Xp. Configure/advanced the advanced options (needs to be upgraded in the future) because it does not advance but rather regressed.
Today it is very common these wi-fi technology increasingly used (hotels,Public Hots Spots,Internet coffe,) growing free bublic wifi projects. The wifi funktions on windows need debugging and modernize.The quality of Wi-Fi is now the operating system
is now a thing order which is not good then the operating system is unusable.

Hi,
For changing the MAC address for Windows 7 is designed with some limitation, we cannot get over it. Thanks for your understanding.
Under Windows 7, the possible range of spoofed addresses for wireless adapters that can be set is limited. To be used by Windows 7, a spoofed MAC address should have 0 as a least significant bit (unicast) and 1 as a second least significant
bit (locally administered) in the second nibble. Thus possible values for the second nibble are limited to 2, 6, A and E.
In other words
MAC address: “XY-XX-XX-XX-XX-XX” “X” can be anything hexadecimal. The hexadecimal “Y”, written in binary format, is Y: “kmnp”, where “p” is the least significant bit;
p=0 --> unicast;
p=1 --> multicast;
n=0 --> globally assigned MAC;
n=1 --> locally administered;
So, actually MAC can be changed to any combination in which p=0 and n=1;
“Y” can be 2, 6, A or E.
So the possible MAC addresses in Windows 7 for wireless adapters:
X2-XX-XX-XX-XX-XX
X6-XX-XX-XX-XX-XX
XA-XX-XX-XX-XX-XX
XE-XX-XX-XX-XX-XX
