Usually very fast, Sometimes painfully slow. Why?

There probably is no simple answer to this, but I'll ask anyway.
I am test driving Aperture 2.0.1 and so far like it a lot. But every now and then, on particular photos, it seems to slow to a crawl. For example, I have one photo that I shot a couple of days ago that has a stone building and a tree (with lots of thin twigs and no leaves) in front of it. This photo is just plain painful to work on -- all adjustments are slow, the loupe takes a couple seconds to open and can't be moved smoothly (it seems to jump erratically, so it's even hard to move it slowly), and even if I zoom to 100% I can't move around in the photo (using the little red navigation box in the navigation overlay) without similar erratic behavior. Even Quick Preview mode is slow!
The odd thing is that with the majority of my photos everything is very quick. Using the loupe feels almost like moving a real, physical loupe over a real photo -- it's that fast. There are just a few images that seem to cause this painful slowness.
So now the question -- is there a reason for this, and a cure? The best explanation I can think of is that this photo, and a few others, has so many little details in it (the roughness of the stone, and the randomness of the many thin twigs on the tree) that it's straining Aperture's raw conversion to its limits. But if that were it, I'd think that Quick Preview would have worked OK. And while I hate to say it (because this is an honest question, not a thinly veiled jab at Aperture), Lightroom doesn't seem to have any problem with this photo.
Other particulars -- I'm using a Nikon D50, and the photo was shot in raw. I've tried quitting Aperture and restarting it, logging out and back on, and even restarting the computer.

I think I have tracked the problem down -- it's highlights and shadows. If I turn that adjustment off everything works fine. I went back and looked at some other images and sure enough, if I turn on highlights & shadows the performance bogs down considerably. It's more pronounced on the particular photo I wrote about yesterday -- until that photo it was just a curiosity and I never made the connection, but this one was so bad that I was forced to check it out further.

XP computer painfully slow when latest Firefox is installed

I have a win vista computer which has worked for years and run Firefox fine, Two weeks ago I upgraded firefox as usual and Firefox became painfully slow. A nerdy friend tried reloading the latest Firefox and concluded Firefox was much slower than Explorer or than Opera. My wife is very unhappy. What do I do now?

Well you could start with giving us the troubleshooting information from the Firefox installation that's having problems<br>
*Click the Firefox button at the top left, then click the ''Help'' menu and select ''Troubleshooting Information'' from the submenu. If you don't have a Firefox button, click the Help menu at the top and select ''Troubleshooting Information'' from the menu.
Now, a new tab containing your troubleshooting information should open.
*At the top of the page, you should see a button that says "Copy text to clipboard". Click it.
*Now, go back to your forum post and click inside the reply box. Press Ctrl+V to paste all the information you copied into the forum post.

I'm using Image Capture over one year, between my Epson XP-800 and iMac, sometimes very fast and quiet often very, very slow. I've tried to use Epson Scan 3.7.9fO but not compatible with OS X 10.9.5x Why, please..

I'm using Image Capture over one year now, using wireless between my iMac and Epson XP-800 and sometimes very fast scans and quiet often very, very slow scans. I have tried to use Epson Scan Software 3.7.9f0 but not compatible with OS X 10.9.5x. There is very little other wireless traffic and I have a fast broadband connection. Thanks

Mike,
Thanks, but, I don't want more software as I have used both Epson and Image Capture. Is there not a solution with existing Epson and Image Capture..?

Why my Illustrator CC is now very slow for opening a 2MB AI file (about 5 minutes), at the beginning (1 month ago) it was very fast (10 seconds).

Why my Illustrator CC is now very slow for opening a 2MB AI file (about 5 minutes), at the beginning (1 month ago) it was very fast (10 seconds).

Assuming that you system meets minimal requirements for CC, make sure you have enough space on your hard drive. By saying enough, I try not to cross 3/4 of its capacity but trivially saying, the more free space the better and the faster the drive the better (I've been considering an SSD drive but still running a regular HDD).
If you are on Windows, clean up the %TEMP% folder regularly and keep the disk neat using the defragmentation tool.
Click Start>Run>enter %temp% , wait for the files to load and select all, hit Shift+DEL to remove them permanently.
For the defrag tool, you can use either the defrag /? command from the command line or right-click the drive, click Properties > Tools > Defragmentation>Defragment Now
Other than that it requires deeper analysis to find performance bottleneck.

My computer is extremely slow, with the rainbow wheel appearing with every click. It is one year old, and has all the most recent updates. Why is it so painfully slow?

That sounds horrible. There are a number of reasons it could occur.
The first thing to do is ensure you have adequate backups, because what you describe can be a symptom of impending disk failure.
To help determine the possible causes of this behaviour read the following. None of what follows is intended to fix anything, but it will provide the additional information required to advance troubleshooting. There are four separate parts to it; read everything first.
Boot OS X Recovery by holding ⌘ and r (two fingers) while you start your Mac. At the Mac OS X Utilities screen, select Disk Utility. Select your startup volume (usually named "Macintosh HD") and click the Repair Disk button. Describe any errors it reports in red. If Disk Utility reports "The volume Macintosh HD appears to be OK" in green then you can be reasonably (though not completely) assured your hard disk is in good working order.
When it finishes restart your Mac and test again for operation. If it's still not behaving as you expect it should, please post the results of EtreCheck in accordance with the following instructions:
Apple Support Communities contributor etresoft wrote a very useful app to quickly gather certain system information that may help point to a cause of this problem. Read about it here. It contains a link to download EtreCheck. Don't download it from anywhere else (such as may be found by following the results of an Internet search).
Click Open - etresoft contributes to this forum frequently and can be considered a trustworthy developer.
It will take a moment to run as it collects its data.
Copy and paste its output in a reply.
Do not be concerned about anything that says "Problem" or “failed” or anything else that may appear in red.
EtreCheck was designed to remove any personal information (such as your computer's name and serial numbers) but if you see anything that looks like an email address or any other personal information that should not be divulged to others, please delete or obscure that information when you post the reply.
When you are finished with EtreCheck, quit the program. It occupies very little space, and you can keep it or drag it to the Trash as you wish.
After completing the above please determine if the problems also occur in "Safe Mode":
Safe Mode or "Safe Boot" is a troubleshooting mode that bypasses all third party system extensions and loads only required system components. Read about it: Starting up in Safe Mode
You must disable FileVault before you can start your Mac in Safe Mode.
Starting your Mac in Safe Mode will take longer than usual, graphics will not render smoothly, audio is disabled on some Macs, and some programs (iTunes for example) may not work at all.
Merely starting your Mac in Safe Mode is not intended to resolve the problem, it's to observe its performance without certain additional components.
To end Safe Mode restart your Mac normally. Shutdown will take longer as well.
System performance problems for reasons that cannot be isolated to any other cause justify an SMC reset. Be sure to read the procedure carefully and follow all the steps exactly as written, even if they seem inapplicable or trivial.

Contacts app is very very slow; why?

With my Z1, searching for contacts was very fast. It was real-time as I type the characters.
With my Z2, it is unacceptably slow. It can be a few minutes to search for contacts. Even when I go to Favouites where I have only eight contacts, the page takes a while to load. When I go to Contacts and search for a contact it can take a few minutes for the contact to be found. Then, when I select that contact, it can take a few minutes again to display the content.
Why is that?
Yes, I have many contacts (maybe 4,000+) and many are duplicates linked from Exchange and LinkedIn. But even when I turn off Auto-Sync, it can still be unacceptably slow.
And I don't keep many apps open at the same time.
What are the possible things I can try?
Thanks,
CWL88

I'm afraid it's not possible to disable the online search. Even if you disable synchronization of contacts it will still search against the server. I will forward this as feedback internally but currently you would need to remove the ActiveSync account to stop online search. A workaround may be to use another client instead like Moxier, RoadSync or Nitrodesk.
The more contacts you have the longer it will take to load all contacts if it's no longer stored in RAM. You can force contacts to stay in RAM but to avoid it being closed, close other apps when you're not using them by pressing the lower right icon and swipe them away. But Z2 has 3GB RAM so usually this is not needed but it depends on what other apps you have any how much RAM they use.

Q 10 became extremely slow in responding after update to 10.2.1.537 - battery draining very fast since, too

Hi,
my Q10 now got very slow after the update to 10.2.1.537
It takes ages for switching from e.g. text to E-Mail Inboxes, from Hub to oriority Hub view or just to opening an email or an app. Also, it s draining the batterry very fast. Down to 20% after only 3 hrs , and than it is switching off. Even in Aircraft mode the battery is down after 5 hrs without me even touching the device.
Any clue what went wrong?

I am also experiencing all kinds of problems since the 10.2.1.537 upgrade. I now have to reboot my Q10 constantly as it will just freeze intermittently! After making a call I sometimes have to wait 5 minutes+ untill I can make another call. My battery also drains very fast - I have to charge it everyday.

Is it a slow motion video? iPhoto does not understand the slow motion tags created by some cameras, eg.g. the iPhone back camera.

Why is Firefox Painfully Slow After Upgrade?

Ever since Firefox went from version 3 to version 4 it has gotten worse and worse! I kept upgrading up to version 6 hoping it would somehow get better, but it has not! It was SO painfully slow that it would bring my whole system to a screeching halt. I am a long-time Firefox user and have promoted it to everyone who's still stuck in IE - but now I myself have switched to Google Chrome just because it WORKS and works FAST! Please, whatever you have to do to make Firefox work as fast as it used to - please fix this problem!! I've just downgraded back to version 3 just so I can use Firefox for some web development I need to do using Firebug...

I run very few or no extensions with the exception of Java and Flash. I never, '''NEVER''' use stupid toolbars. The problem with FireFox on OS X Lion seems to be related to the OS. The speed of my Internet connection never changed and it continues to be fast for all of my computers, both Mac and Windoze 7.
If you change your default DNS on the Mac to something like the IP address of the Google DNS servers, FireFox and Chrome will run at normal speeds. If anyone needs help with this, please post another message and I will post instructions.

Scrolling slow with initial marquee selection, but very fast when adding to selection

I've found that when I zoom in and try to make a selection that requires me to scroll beyond the viewable area, the scrolling becomes very slow when I scroll down. And if I add to the selection (via shift) the scroll becomes very fast, as if the shift key nudges the screen by x number of pixels, just as if I were to shift-move a layer. Is this the intended behavior?

Ramon, my apologies. I own a MacBook Pro running OS 10.5.6, 2.4 GHz prcoessor with 2 GB of RAM, and 256 MB of VRAM. I'm using Photoshop CS4.
So I ran a couple tests and I think I know what's occurring. The scroll speed seems dependent on how close or far the cursor is from the canvas edge (the axis in between the image and the scrollbar). So for example, if I were to do a max zoom the window would expand to the very edge of the desktop. When I start the marquee and move my cursor to scroll it's unable to move any further from the axis because of the desktop edge. This would cause it to scroll more slowly.
Here are a couple of test vids (The zoom is at 3200% and I set up the camera to focus on the top right of the screen):
Window right up against desktop edge (automatically positioned via Photoshop max zoom)
http://s87.photobucket.com/albums/k156/darthsauce/mac/?action=view&current=horiz01.flv
Window edge moved a little away from desktop edge
http://s87.photobucket.com/albums/k156/darthsauce/mac/?action=view&current=horiz03.flv
Window edge moved past the desktop edge (but axis is still visible)
http://s87.photobucket.com/albums/k156/darthsauce/mac/?action=view&current=horiz00.flv
Could this be considered an oversight in the design since zoom automatically resizes the window for us (of course, this would affect users differently depending on their zoom ratio and display resolution)? This means that I'll have to resize the window each time the zoom fills the desktop in order to scroll at a proper rate.

Updated to LR 5.4, images now importing extremely slow. After importing and rendering images are still very slow to go through and develop. No issues in LR 5.3 which was very fast.

After importing and rendering images are still very slow to go through and develop. No issues in LR 5.3 which was very fast. Canon,Nikon, Leica and Fuji files all rendering slow. iMac 2.9 ghz 16gb RAM OSX 10.8.5. Catalogs and images are kept on external drives. Drives running fine. Really need a fix on this since I'm norally imported and processing at least 4,000 images per LR Catalog. Is there way to revert back to 5.3? I can't use 5.4 is its current state. Thanks.

Download LR 5.3 and install it
By the way, lots of people have this complaint about LR 5.4, and the advice I give is to use LR 5.3 unless you need one of the new camera models supported by LR 5.4

None of my pictures that I uploaded into iPhoto are in my Finder under Pictures. Should I copy and paste my folders from iPhoto into here, in case something happens to my iPhoto program (in addition to backing them up onto an external hard drive like I already do)?
No, that's just wasting space. A back up needs to be on a different disk.
Your photos are within the iPhoto Library.

Painfully slow startup - any suggestions how to make it faster?

Hi Everyone,
Just thought I'd ask people - my 17" iMac G5 1.9GHz PowerPC with 512MB ram is painfully slow at start-up. Seems to take forever! Does anyone know how I could clear a lot of rubbish from my computer and someone make it faster.
Would anyone recommend a complete re-install - would that improve speed?
Any help appreciated, cheers,
Mark

Mark, you can clear space on your drive and speed it up by moving a lot of sound and video files to a DVD, or even better, to an external; Firewire drive that you can partition and also use as a clone boot disk.
Go through your applications folder and look for stuff that you never use, then get AppZapper to remove all traces of them. You can also use Monolingual to remove the tons of extra languages installed with Word and OS X, just make sure you uncheck English and any other language you might use.
Hope some of this helps,
Miriam
