Stage3D much slower in Desktop Air than in Browser?

Same setup. Some moving cubes and spheres.
FPS in Adobe air desktop app: 29
FPS in Browser: 58
Any tweaks I should attempt?

Ok, I'm stupid. Had 2 enterframe handler running at the same time ....

Building smart previews much slower in Lightroom 6 than in Lightroom 5

Building smart previews is much slower in Lightroom 6 than in Lightroom 5.
Creating a smart preview from a DNG (Fuji X-E1 raw file) takes about 12 seconds.
Enabling/disabling GPU accelaration does not really make a difference.
When monitoring the Lightroom process with Process Explorer the GPU usage is always 0.
Below is my system specification.
Anyone got some idea why this might be?

I know that is the official line but copying speed is fine in Windows 8 under Parallels. I have the latest Windows 8 Broadcam driver installed for the network adapter in Boot Camp and everything else works fine.
I can download a file from the Internet 10x faster than I can from my Airport disk in the next room in Boot Camp!

Can HTML based browsers rotate along with a Desktop AIR application if browser is modular?

I get a buged out browser module in my Desktop AIR application after doing an application level rotation/orientation-change/flip screen for viewing on other side of monitor .
Most of the HTML content rotates 180 degrees without any issue, but, it seems some of the "components" aren't getting with the program.
Dropdown box lists don't rotate, even though the button to initate use of the dropdown list does. So, when viewing the application from the new orientation,
the dropdown lists are upside down from an end user perspective ( just never rotated properly from a developer perspective )
I was having to flip my application by sending out a message to a service and recieving the call from a WCF to tell the whole OS to flip via WIN32 API but
64bit operating systems do this a lot slower, so i'm trying to find a new solution.
I am wondering if a workaround can be done by replacing the misbehaving things like the dropdown box with native flex components?
Any thoughts/ideas/conclusions?

Why is animation so much slower in 2.2 than 2.1?

I have a pretty gnarly translate/scale animation running on my Mac in jdk 7u7 or jdk 7u10. Javafx 2.2.x doesn't seem to be able to handle it. The animation is choppy and slow. I had the exact same animation in 2.1/jdk 6 on the same computer and it was smooth and fast.
Any reason for this? Is there any way I can tell if GPU is being used?
Thanks!

I wonder how this performs when you use the setup Java 7 update 5 + JavaFX 2.1 (so only upgrade the JDK, not JavaFX). If only to rule out that the problem actually originates from the JDK update and not JavaFX specifically.

Matlab code much slower in Labview MatlabScript than in Matlab

I was using an algorithm written in Matlab that executed in less than 2 seconds. Now I need to use it within a Labview program and I am using Matlab script with the same algorithm, but it lasts 10 times longer than in Matlab. Is this normal? Thank you!

How do you know that it is 10 times? Did you create a benchmark?
What are the conditions for the benchmark? Can you provide the code for it?
I am asking this because if you create the VI and put the m-script in the script node, and then press run (looking on the watch) and wait for the VI to finish, you "benchmarked" compile times, memory allocation as well as the complete VI's execution (including the script node of course). I doubt that this will ever be comparable to the "benchmark" in MatLab.
If you provide your VI, we might also be able to give some hints to increase performance.

HT4623 Is there any way to get iOS 7 off my iPad? It is MUCH slower and less responsive than it was! Why do you people always have to fix something that isn't broken?

Is anyone else experiencing sluggishness and the need to practically pound the screen to get a response from the keyboard?

(A) Reset iPad
Hold down the Sleep/Wake button and the Home button at the same time for at least ten seconds, until the Apple logo appears
Note: Data will not be affected.
(B) Reset all settings

Safari and Firefox much slower than my old Windows notebook

I'm a new Mac user. I have a new MacBook late 2008, OS 10.5.8. Loading web pages is much slower on the mac than my 3 year old Windows XP machine. My former router was a LinkSys, now I have a brand new Airport Extreme.
It works the same way on any network, home or elsewhere. I've tried fixing disk permissions. I can go to Google for example, click on a new page and wait up to 8-10 seconds for the new page to load. The bar at the bottom of the page shows activity.
I'm using the Windows machine to surf now, until I can get this figured out.
I'd greatly appreciate any help. My Macbook is great other than for web.
Thank you.

Sig and others,
Thanks for your comments. This is getting a little scary for a rookie. Is this something I can safely do with no knowledge on networking, etc? That's kind of why I bought a mac. Is there an Apple Support document or thread that will guide a new user on this kind of issue. I'm still using the old PC laptop for web because of the speed issue.
The support guys at the retailer are blowing me off... PC vs Mac kind of deal.
Thanks for your help.

How Can I Improve Mavericks Performance (much slower than 10.8)?

When I upgraded to OS 10.9, I immediately saw a significant slower performance than with 10.8 or 10.7 (which I had been using for about two years). One big difference was a delay with the boot disc thrashing a lot when I started the computer and when I launched any app. That is, after starting my Mac Pro (2008), once the windows are all visible, there is a 30+ second delay (with the boot disc thrashing a lot) before it responds. A very similar thing happens when I launch any app. For example, when I launch iPhoto, after the photos appear, it takes 30+ seconds before it reponds to any mouse clicks. Under 10.7 and 10.8, there was about a 5 second delay (which I always thought was Faces doing its thing). This disc thrashing and delay before the app will respond happens with every app (Word, iMovie, Disc Utility, etc.) These delays never occured under 10.7 or 10.8.
A few people on the Apple Support forum suggested I run EtreCheck and remove various apps that they said could cause a problem with the OS. I removed every app they suggested, but I do not see any difference in performance. In my opinion, OS 10.9 has implemented something new that is causing my Mac Pro to run much slower.
I just ran a Safe Boot (using shift key while starting). I don't see any difference.
I would appreciate any advice.

First, back up all data immediately unless you already have a current backup. If you can't back up, stop here. Do not take any of the steps below.
Step 1
This diagnostic procedure will query the log for messages that may indicate a system issue. It changes nothing, and therefore will not, in itself, solve your problem.
If you have more than one user account, these instructions must be carried out as an administrator.
Triple-click anywhere in the line below on this page to select it:
syslog -k Sender kernel -k Message CReq 'GPU |hfs: Ru|I/O e|find tok|n Cause: -|NVDA\(|pagin|timed? ?o' | tail | open -ef
Copy the selected text to the Clipboard by pressing the key combination command-C.
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Paste into the Terminal window (command-V). I've tested these instructions only with the Safari web browser. If you use another browser, you may have to press the return key.
The command may take a noticeable amount of time to run. Wait for a new line ending in a dollar sign (“$”) to appear.
A TextEdit window will open with the output of the command. Normally the command will produce no output, and the window will be empty. If the TextEdit window (not the Terminal window) has anything in it, stop here and post it — the text, please, not a screenshot. The title of the TextEdit window doesn't matter, and you don't need to post that.
Step 2
There are a few other possible causes of generalized slow performance that you can rule out easily.
Disconnect all non-essential wired peripherals and remove aftermarket expansion cards, if any.
Reset the System Management Controller.
Run Software Update. If there's a firmware update, install it.
If you're booting from an aftermarket SSD, see whether there's a firmware update for it.
If you have a portable computer, check the cycle count of the battery. It may be due for replacement.
If you have many image or video files on the Desktop with preview icons, move them to another folder.
If applicable, uncheck all boxes in the iCloud preference pane. See whether there's any change.
Check your keychains in Keychain Access for excessively duplicated items.
Boot into Recovery mode, launch Disk Utility, and run Repair Disk.
If you have a MacBook Pro with dual graphics, disable automatic graphics switching in the Energy Saverpreference pane for better performance at the cost of shorter battery life.
Step 3
When you notice the problem, launch the Activity Monitor application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Activity Monitor in the icon grid.
Select the CPU tab of the Activity Monitor window.
Select All Processes from the View menu or the menu in the toolbar, if not already selected.
Click the heading of the % CPU column in the process table to sort the entries by CPU usage. You may have to click it twice to get the highest value at the top. What is it, and what is the process? Also post the values for User, System, and Idle at the bottom of the window.
Select the Memory tab. What value is shown in the bottom part of the window for Swap used?
Next, select the Disk tab. Post the approximate values shown for Reads in/sec and Writes out/sec (not Reads in andWrites out.)
Step 4
If you have more than one user account, you must be logged in as an administrator to carry out this step.
Launch the Console application in the same way you launched Activity Monitor. Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select
View ▹ Show Log List
from the menu bar.
Select the 50 or so most recent entries in the log. Copy them to the Clipboard by pressing the key combinationcommand-C. Paste into a reply to this message (command-V). You're looking for entries at the end of the log, not at the beginning.
When posting a log extract, be selective. Don't post more than is requested.
Please do not indiscriminately dump thousands of lines from the log into this discussion.
Important: Some personal information, such as your name, may appear in the log. Anonymize before posting. That should be easy to do if your extract is not too long.

Is the Core i7 processor comparable, much slower, or faster than the 2.8 Ghz core 2 duo from 2009?

I am looking to get a new MacBook Air, but when looking at the prices I am seeing the MacBook Pro 13" for the same price and a lot more guts (RAM and Processor). I am ok with spending the amount of money on the air if it means I get a computer that is like my iPad, which i love (flash based, snappy), but don't want it to be super slow.
I am coming off of a 17" 2.8Ghz MacBook Pro from 2009. I was happy with the speed and power of that machine. The most taxing thing I did was make a complilation of family movies in iMovie and burned them with iDVD once in the 2 years of ownership.
I mostly browse the internet and compose written documents, and keynote presentations.
I know my questions may seem stupid, but I don't know how significant the changes between i7 and Core 2 Duo are, so I ask the question:
I am wondering if the processing power in the core i7 will be somewhat comparable, much slower, or faster than the 2.8 Ghz Core 2 Duo I had in my 2009 computer?
Thanks for any help!!

Hi brosephb,
Like you I went through a similar comparison process. I bought the MacBook air 13" and up specced the processor and memory. I don't do anything taxing enough or frequently enough to NEED the extra power of the MacBook pro.
I am overjoyed at my air. It's gorgeous, the way it wakes instantly, it's speed and it's portableness is so endearing that I just don't use my iPad anymore. I read numerous reviews on it and the overwhelming opinion was it's addictive ease of use because of it's slim, light and rapid waking. At work I can hold the air with one hand, open it rapidly at will. It's just great but it's made my iPad redundant (for me anyway).
I see the new airs are even faster and I'm tempted to consider selling my 6 month old air and getting the new one, but, it runs a dream so I am happy to just be envious of the new one.
In short, unless you need the power (for your work) go for the air. I'm looking at a new iMac to use as a home work station. For the price of a new air I can get an iMac that will swallow any task for a good few years to come. And my air will suffice as my mobile companion. However, that's just me spoiling myself as, at the moment, I have no teal need for another mac. I may get the cinema display for any long winded tasks, as the screen size will help with multiple tasking.
A bit of a ramble, hope this is useful.

My four year old iMac is running much slower than when it was new. Any suggestions on cleaning out the cob webs?

My four year old iMac is running much slower than when it was new. Does anyone have any suggestions on what I can do to "clean it up" and get it running like it used to?

What year, screen size, CPU speed and amount of RAM installed?
To find out info about your system,
Click on the Apple symbol in the upper left of the OS X main menu bar. A drop down menu appears.
Click About this Mac. A smaller popup window appears. This gives you basic info like what version of OS X your iMac is running, the speed of your iMac's CPU and how much RAM is installed.
Click on the button that says More Info. A larger window appears giving you a complete overview of your iMac's hardware specs.
Highlight all of this info and copy/paste all of this into another reply to this post, editing out your iMac's serial number before actually posting the reply.
This will tell us everything about your iMac so we may begin to help with your iMac issues.
How full is your Mac's hard drive?
Locate your iMac's hard drive icon on the OS X desktop. Click the icon once, then use the keyboard key combination Command-I. This will give you additonal info about your iMac's internal hard drive.
Post this info in your reply here, also.
Here are some general tips to keep your Mac's hard drive trim and slim as possible
You should never, EVER let a conputer hard drive get completely full, EVER!
With Macs and OS X, you shouldn't let the hard drive get below 15 GBs or less of free data space.
If it does, it's time for some hard drive housecleaning.
Follow some of my tips for cleaning out, deleting and archiving data from your Mac's internal hard drive.
Have you emptied your Mac's Trash icon in the Dock?
If you use iPhoto, iPhoto has its own trash that needs to be emptied, also.
If you store images in other locations other than iPhoto, then you will have to weed through these to determine what to archive and what to delete.
If you use Apple Mail app, Apple Mail also has its own trash area that needs to be emptied, too!
Delete any old or no longer needed emails and/or archive to disc, flash drives or external hard drive, older emails you want to save.
Look through your other Mailboxes and other Mail categories to see If there is other mail you can archive and/or delete.
STAY AWAY FROM DELETING ANY FILES FROM OS X SYSTEM FOLDER!
Look through your Documents folder and delete any type of old useless type files like "Read Me" type files.
Again, archive to disc, flash drives, ext. hard drives or delete any old documents you no longer use or immediately need.
Look in your Applications folder, if you have applications you haven't used in a long time, if the app doesn't have a dedicated uninstaller, then you can simply drag it into the OS X Trash icon. IF the application has an uninstaller app, then use it to completely delete the app from your Mac.
To find other large files, download an app called Omni Disk Sweeper.
Download an app called OnyX for your version of OS X.
When you install and launch it, let it do its initial automatic tests, then go to the cleaning and maintenance tabs and run the maintenance tabs that let OnyX clean out all web browser cache files, web browser histories, system cache files, delete old error log files.
Typically, iTunes and iPhoto libraries are the biggest users of HD space.
move these files/data off of your internal drive to the external hard drive and deleted off of the internal hard drive.
If you have any other large folders of personal data or projects, these should be archived or moved, also, to the optical discs, flash drives or external hard drive and then either archived to disc and/or deleted off your internal hard drive.
Good Luck!

Preview takes forever to open, much slower than on my old MacBook. It has been like this since I bought the computer last January. Why is Lion so much slower?

Preview takes forever to open, much slower than on my old MacBook running Snow Leopard. It has been like this since I bought the computer last January. Any ideas?

Take it to an Apple Store for testing. If you don't get immediate satisfaction, exchange it for another one, which you can do at no cost, no questions asked, within 14 days of delivery.

PS CS3 much slower than CS2 on Intel Mac. I don't get it.

Yes, very very strange.
I work with very large files, so I just got a spiffy new Mac Pro. It's my first Intel machine, so I expected that CS2 would drag a little bit, due to Rosetta. In fact, moving from one processor to eight of them seems to have much more than compensated. Nevertheless, I ordered CS4 and while I wait I downloaded the demo of CS3.
I expected that CS3 would fly (no Rosetta) but have found my test tasks taking an inordinate amount of time... much slower than CS2 on the same Xeon workstation, and slower than CS2 on my old iMac (single 2.1GHz G5)
Since I work with extremely large files, I got a hardware RAID5 made up of four 15,000RPM SAS drives. I can't get enough RAM to avoid using scratch disk, so I attacked the biggest performance bottleneck. I did get 8GB of RAM; would have gotten more, but I read that it won't matter until CS goes 64-bit in CS5 at the earliest.
The rest of it: dual quad-core 2.8GHz "Woodcrest" Xeon processors, NVIDIA GeForce 8800GT graphics card, OS X 10.5.5, all updates (Apple and Adobe) applied as of 6pm Wednesday October 8th.
I'm running two tests as my benchmark: open a file (PSD created with CS2, 75" x 75" at 400ppi, two layers, RGB with one additional channel) and resize to 75" x 75" at 800ppi. Once that is done, I rotate the new, massive file counterclockwise 18.5 degrees.
On my old setup, 2.1GHz SP G5 iMac with CS2, these tasks took 38m 30s and 1h 33m 22s respectively.
New machine with CS2: 10m 09s and 29m 14s respectively
New machine with CS3: 42m 38s and 1h 36m 24s
(above tests run repeatedly: these numbers are the fastest numbers for each configuration)
I have nothing else running for these tests, except for Activity Monitor. What I've observed with Activity Monitor: the old G5 was pegged at (or very near) 100% CPU the whole time. Mac Pro with CS2, Photoshop ran most of the time on one CPU at a time, but spiked up as high as 250% CPU usage just for Photoshop.
I haven't seen Photoshop CS3 use more than 80% of one processor the whole time on the Mac Pro. Mostly it sits around 35%.
One more informal test: if I open that same file and downsample from 400ppi to 200ppi, CS2 does it in 1m 40s. CS3: 6m 57s. I don't have the iMac any more so I can't tell you how long it would take there.
In both CS2 and CS3 the scratch disk is my startup volume, but it's a RAID. I can't add any more drives except for external drives. I could have configured it to one dedicated system drive and a second scratch volume made up of the remaining three drives, but I consulted with people who know RAID better than I do who agreed that since everything is going through the SCSI controller and everything gets written to multiple drives in order to make it faster that I'd get a performance hit by splitting the RAID into two volumes, even if multiple processes are trying to get at the same drive array. Even adding a Firewire 800 drive for scratch would be slower than using the RAID. Or so I've been told.
So, this seems absurd. CS3 is not using Rosetta, right? So it should be flying on my machine. What on earth could I have done to a fresh CS3 (demo) install to make it slower than CS2 on my old G5? Is the CS3 demo crippled? Is there a conflict having CS2 and the CS3 demo on the same machine?
I'm stumped.

>Ya see, this is the attitude you really, really should get over. The Photoshop CS3 (10.0.1) code is just fine... it's your system (hardware/software) which, for some reason is not providing an optimal environment.
Jeff, I agree completely. You seem to be assuming that I actually think Adobe wrote bad code. In fact, I believe Adobe did NOT write bad code (and I wrote that) but that the condition that you are suggesting (CS3 being slowed by having having scratch and system on the same volume to a far greater extent than CS2) could only be caused by bad code by Adobe. Since I believe that, as you say, a universal difference of this magnitude between CS2 and CS3 would be noticed by huge numbers of users, I doubt that what I am seeing is the result of having scratch and system on the same volume.
In case I'm being less than clear:
Scratch and system were on the same volume for CS2.
Scratch and system were on the same volume for CS3.
On my system CS2 performs tasks three to four times faster than CS3.
ergo, either there is some problem other than scratch and system being on the same volume (perhaps something that exacerbates the scratch/system/same volume issue, OK, I accept that possibility) or else the change has been between CS2s and CS3s handling of scratch disks.
If for the sake of argument we rule out the possibility that CS3 handles the condition of scratch and system being on the same volume worse than CS2 does, the only possibility left is that there is SOMETHING ELSE WRONG WITH MY SYSTEM.
I am trying to find out what that other thing is. You're the one insisting that scratch and system being on the same volume is the cause of the CS3 slowdown. Accusing me of not believing that there's something wrong with my system misses the mark entirely. I ABSOLUTELY believe there is something wrong with my system.
> Your RAM tests sound pretty thorough, but if I had your large-files workflow I would buy two (or preferably 4) 4-GB sized matched RAM DIMMs, remove all the existing RAM, and install only the new RAM to further test whether or not the old RAM is anomalous.
Thanks Allen,
Actually, this is exactly what I've done, though in a different order. My system shipped with two 1GB chips. I bought two 4GB chips from OWC and installed them, and found my CS2 performance to increase significantly. It was only then that I tried installing the CS3 demo. When I found CS3 running my tests more slowly than expected, I pulled the new RAM out and tried with just the original 2GB and tested both CS2 and CS3 again. Then I took the original 2GB out, put only the new RAM in and tested CS2 and CS3 again, finding the same results. Currently I have all 10GB in the system and for the moment I'm setting aside the possibility of a problem with the RAM (or at least setting aside the possibility that the RAM chips are just plain bad) because that would indicate that both the new and the old RAM are both bad in the same way. That seems unlikely.
So I guess I'll have to drag the system down to the Genius Bar if I don't see an improvement from rearranging my hard drives.
The update there is that last night I backed up my system, and this morning I deleted my RAID5 set, blowing away everything on my system until I can restore from backup. The new configuration is 1 JBOD drive plus three drives attached as RAID0.
Unfortunately, neither of the new volumes is visible when I go to restore from backup. For the moment, this little experiment has cost me my entire system. The upshot is that it may be some more time before I have any more information to share. Even when I do get it working again, I can expect restoring to take the same 12 hours that backing up did.
I will certainly post here when I've got my system back.

Firefox much slower connecting to all web sites than Internet Explorer. Why?

Over the last few weeks, Firefox has become much slower connecting to virtually all web sites that I frequent than does Internet Explorer. Nothing has changed on my computer other than occasional downloads of Firefox "improvements".

A possible cause is security software (firewall) that blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.
Remove all rules for Firefox and the plugin-container from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process and the updater process.
See:

Start Firefox in <u>[[Safe Mode]]</u> to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance/Themes).
*Don't make any changes on the Safe mode start window.

To run a piece of PL/SQL code, in TT is much slower than in ORACLE.

A piece of PL/SQL code , about 1500 lines, package is named rtmon_event, function in it is named rtmon_SHOLD_CUS_RPT;
the PL/SQL code is run in ORACLE.
Now I want to get fast speed, I think of TT.
I rewrite the PL/SQL code by grammer in TT.
But the speed in TT is much slower than the speed in ORACLE.
In ORACLE, to run the PL/SQL code, it need 80 seconds; but In TT, to run the PL/SQL code, it need 183 seconds;
How can I resolve the problem?
Btw: there are some joins of 2 tables, or 3 tables in rtmon_event.rtmon_SHOLD_CUS_RPT, and some complex DML in it.
The run method is :
declare
a number;
begin
a := rtmon_event.rtmon_SHOLD_CUS_RPT ;
end;
Thanks a lot.

The easiest way to view a plan is to use ttIsql and issue the command:
explain SQL-statement;
For example:
explain select a.ol1, b.col2 from taba a, tab b where a.key = b.key;
See the documentation that 'hitgon' pointed you to to help you interpret the plans.

In CS6, JavaScript Running MUCH Slower than ActionScript

Hi All,
I am finding that in CS6, JS code runs MUCH slower than ActionScript code. I don't want to double-post here - Full details may be found where I posted them in the InDesign Scripting forum at - CS6 JavaScript Running Much Slower than ActionScript, before I realized that this forum might be more appropriate.
The basic gist of it is that I had a Flex/ActionScript Extension, which I obviously needed to start converting to JavaScript in advance of the next version not supporting ActionScript. I converted 20,000 lines of my business logic code from ActionScript to JavaScript (grrr...) - only to find that it now runs 5 times slower than it did in ActionScript.
What has been the experience of others who have converted large Extensions from ActionScript to JavaScript?
I would greatly appreciate any and all suggestions.
TIA,
mlavie
