Photoshop is very slow in lion.

This is the only problem -so far- that I face with Lion. All other apps are working fine and I like some of the features of Lion. BUT:
Photoshop is very slow. I tried disabling font preview. It helped a little but the overall experience of Photoshop is SLOW.
I'm stuck : I like the features of Lion but long for the speed of SL !
Can you help Apple .. Please!

Did you update PS CS4 to 11.0.1?
Also using this guide will help speed things up. It is written for XP and Vista. But if you follow the rules for Vista then it will work with Windows 7.

There are several guides to speed up windows 7 too. Much to do with turning things off running in the background. (Same as Vista).

After Photoshop CC 2014 update - Photoshop is very slow (Windows 7)

After updating today to the latest photoshop cc2014 Version, Photoshop starts very slow and is not useable.
I updated from V. 2014.1.0 to 2014.2.1 20141014.r.257.
Starting Photoshop Needs 6 minutes (before 1.5 minutes). The menue and button reactiontime is more than slow, you cant work with this Setup.
Is there a Problem with the new release?
And please Adobe, dont tell me, my System has a problem. Did only an update on the CC2014 Suite via creative cloud. Old PS Version (2014.1.0)runs great.
After testing a few time, I recovered my System back to Version 2014.1.0 with Windows recovery and Photoshop works good again.
So whats wrong with the new release?

The CC 2014 update 2014.2.1 is a month old and ACR 8.7 is two days old. Something strange is happening to you. First try resetting your Photoshop Preferences. This is a Adobe Photoshop User forum your not dealing with Adobe here. You seem to think you are and your attitude seems like you not open to to possibility that your system may have a problem. I think you may have one..

Photoshop CS6 - Very Slow Brush Speeds...

Hi:
I thought CS5 was bad, but brushing with CS6 all brush strokes are very, very slow. If I make a brush stoke I have literally have to put my hand on my chin and wait for the brush to catch up. I cannot work like this. Any suggestions on what to do to speed up the brushes? Forget about adding anything else to Photoshop, please work on speeding up exisiting functions.

Photoshop CC very slow to open after Win 8.1 upgrade

Hi guys.
I was wondering can you help me. I have tried extensive google searches with no real conclusive answer. I recently upgraded from Win 8 to 8.1. Since the upgrade Photoshop CC is very slow to open. It can take 1-2 minutes to boot up fully. Lightroom 5.2 & bridge open fine. I have a pretty fast system with i7 3.4Ghz Processor & 32Gb of Ram with the OS running on a 256Gb SSD Hard Drive. PS CC booted up fine on Win 8 but not anymore since the upgrade. The only plug-in I run is OnOne Photosuite 8. I have even tried disabling loading extenions at start up from the preferences menu but it makes no difference as it can stil take 1-2 minutes to open. Any help appreciated??

There was a Photoshop update that corrected a problem Adobe had accidentally introduced with a link that went to a network resource that is not available for anyone outside Adobe. But that was a while ago. See: Re: Photoshop CC startup slow (much harddisk access)
I've had Win 8.1 all along and never had an update cause a slowdown.
Unfortunately problems that go away on their own often return on their own. I hope that's not the case for you and that it continues to work properly.

Very Slow Internet Lion (This one is for the "Apple Network Team")

hello,
i'm joão from Portugal, Europe.
a couple of weekends ago i've updated three macs to Lion.
2009 MacMini, 2007 White Macbook, 2010 iMac 21".
problems? only with the iMac.
no connection drops but slow slow slow very slow internet. wired, speedtest marked 15Mbps download. wireless? 1Mbps, 0,3Mbps, 3Mbps, very unstable.
with Snow Leopard everything was ok.
tried every solution from every site and finally got it working flawlessly.
tried clean install instead of update.
tried new dns servers.
tried disabling ipv6.
tried remove wifi interface then add it again.
tried service order.
tried PRAM, NVRAM, SMC, you name it, reset.
tried removing preferences folder.
tried different browsers -> same symptoms.
tried disable/enable airport.
tried 10.7.1, 10.7.2, combo, delta.
tried router's firmware update.
tried putting the computer closer to the router.
tried resetting the router, factory defaults.
tried changing router's channel.
tried disabling router's firewall.
tried watch router's event log, nothing suspicious.
tried disabling router's wep password.
tried pinging a site for a couple of minutes, 2% packet loss.
tried hundreds of pages and forums...
during this attempts, macmini and macbook showed very good wireless internet speed.
iMac? slow, slow, slow, slow, slow, like seeing gmail's loading screen for more than one minute...
again and again speedtest 1Mbps, 0,3Mbps, 1Mbps, 1Mbps, 0,3Mbps, 3Mbps.
discovered the pingtest utility in the same site and iMac's ping was grade C, grade F, grade D, with big values...mac mini and macbook were alwas grade B, with low pings (imagine 25ms on them vs. 138ms on the iMac).
i was fed up with the situation, every week tried and failed. iMac's owner was wanting to get his Lion money back and stick to Snow Leopard again. imagine recent Windows switchers thinking they went back to the same situations....
but then i found this website. and then realised macbook and macmini's wi-fi were both powered by a broadcom chipset. iMac's was powered by an Atheros chipset! did what the guy says on that site (replaced Lion's Atheros kernel driver by the one on Slow Leopard), and now everything is perfect, like on Snow Leopard. very good speed.
what a relief. thank you sir.
hope it can help you.
hope it reachs apple's network developers...this is not good, you can't fail on something so simple and essential as decent wifi quality...

humm...
i've clean installed one macbook (late 2008?) and one mac mini (early 2009) both with broadcom adapters and both of them were ok, after the install.
so, speedtest and pingtest are websites (speedtest.net and pingtest.net), both test your internet connection with the help of a 'local' server. it's useful, for instance, if you want see if two different computers connected to the same router have the same connection quality.
so if you can connect to some routers nicely and you have problems with your router, to me, it seems like you have some problems with the connection between your computer and the router.
an old router might bring you problems (there are some advices on the internet to change router's channel and so...), i would recommend to see if motorola has some sort of firmware update to your router. if you don't have complex router configurations, you might try to reset to factory defaults (search the manual). that, once, fixed a problem with a smc router and two macbooks (one, older, could connect easily, the other wouldn't connect to the router).
if that atheros driver trick, resolved your issue, that's strange
make sure broadcom isn't your ethernet adapter and not your wireless adapter
did you resetted your pram and smc? do you have Mac OS 10.7.2?
i hope you can figure that out.

Illustrator and photoshop close very slow

I have a strange problem here.
When i save some filse in one of the programs and want to close only the file window, it closes very slow. Even if i only oppend the file, with no work done over it. Even if i open a blank file and want to close it. It often takes 10-20 sec just for that.
I'm runinng win7 64 bit professional with cs5 production premium.
Computer is hp z400 workstation.
What could it be?

There is no way the computer is slow.
It is - if it is misconfigured or poorly maintained. All your symptoms quite clearly point to issues with your temporary directories, user home directory and the system swap file, in turn inevitably leading me to the conclusion that you are either using a slow SSD drive or have a problem with your SATA/IDE controller. Probably it's running in some slow legacy compatibility mode even. Look into those things and also read this article on my pages for some general guidance. Maybe something applies to your situation and it can be fixed easily.

Photoshop is very slow in my computer (win7 x64)

I don´t know what happen, since i had winVistax64, and now that I have win7x64 photoshop works really slow (brushes, all!!) I can´t do anything normally, takes a while to paint, is really annoying... for info i have a laptop Sony VAIO with 4GB, intel core 2 duo 2,26Ghz... I don´t think that the computer is the problem . Please, please help!!

Aperture 3 very slow on lion

running on my macbook pro 2.66 ghz core 2 duo with 4 MB of ram, aperture 3 was lightning-fast in snow leopard, now is mud-slow in lion. as in *unbelievably* slow. is a fix coming?
f

I had taken the route, over time, of installing Lipn, ontop of SL, ontop of Leopard -- after the upgrade to Lion, Aperture became painfully sluggish. After scouring user forums and a lot of Google searching, I found the one suggestion where you delete cache from a couple directores and a .plist from Aperture. No real difference.
Finally, after, what I would assume to be frustration and morbid curiosity, I used Onyx's automation clean up tools (checked everything but reindex Spotlight), and went the route of trashing my preferences. Full contents.
Long story short, Aperture is in the process of importing and processing about 59k photos and remaining much much more responsive. Instead of taking 36 hrs to complete like before, it's on track to complete everything in about 6.
Lion, as a whole, also seems snappier.
We'll see what happens when Aperture completes processing, but I am a lot more optimistic. I suppose should THAT fail, i'll go the clean-install route.
But, yeah, installing OS ontop of OS ontop of OS is never a good idea, no matter what anyone says -- you wind up with some cross tangled schmutz...

Adobe Photoshop CS6 Very Slow On Rendering Type

I have a notebook with specification as mentioned below :
Lenovo Ideapad Y470P
2nd generation Intel Core i7-2670QM Processor( 2.2GHz 1333MHz 6MB)
Windows 7 Ultimate x64
AMD Radeon HD 7690 2GB
8.0GB PC3-10600 DDR3 SDRAM 1333 MHz
750GB 5400
I'm using Adobe Photoshop CS6 (64 Bit) for doing my job.
Right now, i have a task to create a banner with dimension 800 x 900 Centimeters with Resolution 300 DPI and Color Mode RGB 16 Bit.
The file size when blank is about 56.1 GB.
The problem is, when i add some text with Horizontal Type Tool and click on the Move Tool, the Rendering Type screen show up and take a very very long time to finished.
I have made some configurations to my Photoshop that i found on Adobe Forum, but the problem still persisted.
Some configurations that i've made is :
- Turn off the Automatically Save Recovery Information
- Set Maximize PSD and PSB File Compatibility to Ask
- Set the Memory Usage to 95%
- Set the Cache Levels to 8 and Cache Tile Size to 1024K
- Set the Graphics Advanced Settings to Drawing Mode Advanced, and Check the option Use Graphics Processor To Accelerate Computation, and Uncheck the option Anti-Alias and 30 Bit Display
- Set the Scratch Disk to another partition ( C:System D:PageFile E:Data F:Scratch Disk)
And after all of that configuration, my Photoshop still slow when Rendering Type.
Could you give me some tips to solve my problem?
Thanks

300 ppi for a banner that size is categorically not normal. Guaranteed.
Get specific instructions from the shop that is going to print it.
You keep confusing ppi with dpi. The resolution of an image file really is expressed in ppi, pixels per inch, not "dpi" which is dots per inch. The precise terminology is as follows:
DPI = Dots per inch = units used to measure the resolution of a printer
LPI = Lines per inch = The offset printing 'lines' or dots per inch in a halftone or line screen.
PPI = Pixels per inch = the number of pixels per inch in screen/scanner file terms.
Here's a link to a discussion that may interest you:
http://graphicdesign.stackexchange.com/questions/487/what-ppi-should-a-large-format-artwor k-for-print-be-done-at
It includes the following chart and subsequent comments :
"The rule of thumb is that we need 1.5 to 2 times the LPI in PPI to get acceptable results.
"Viewing Distance   Present Study
20 feet    greater than 10 LPI
18 feet    18.75 LPI or greater
16 feet    18.75 LPI or greater
14 feet    37.5 LPI or greater
12 feet    37.5 LPI or greater
10 feet    50 LPI or greater
8 feet     65 LPI or greater
6 feet     85 LPI or greater
4 feet     100 LPI or greater
2 feet     133 LPI or greater
1 foot     150 LPI or greater
6 inches   150 LPI or greater
"Presumably, for a banner 3m x 5m, you'd be standing at a minimum of, say, 10 feet. (Just eyeballing the wall here.) So, by this table, you'll need 50 LPI minimum. That would mean your raster graphics should be about 100 PPI, or 75 PPI at 12-14 feet. Considering that and the fact that 2x LPI is pretty conservative for reproducing fidelity (often 1.5xLPI is "enough"), this agrees with [the given] advice of 75 PPI being acceptable."
Talk to your printer. I suspect they will want a file at under 75 ppi, or even much less. Follow the printer's advice/request.

Photoshop CS5 very slow performance, MacBook Pro i7

Hi, I've noticed some posts on slow screen redraw, but my issue seems to be with specific performance with web based files having many layers and layer groups.
A sample file is a 27mb psd. It has lot of layers (525), mostly type layers (limited to 3-4 typefaces in the file) and layer groups. If I select a particularly large layer group and try to move it on the canvas, I get the Adobe throbber cursor icon for at least 20 seconds. Even small layer groups bring up the throbber cursor for a few seconds. Overall, things seem much slower than CS4. Not good! And I'm just speaking of basic operations, not hitting intensive tools or major filters yet.
I've looked at the site below, but not much information except the option to purchase some scripts to 'warm-up' Photoshop. After what I spent on Design Premium, I don't think I should have to purchase third party scripts to warm it up. (I did experiment with the tiles option under performance pref's, but upping that made opening files take 2 minutes, where before opening was achieved in 10-15 seconds.
http://macperformanceguide.com/index_topics.html#OptimizingPhotoshopCS5
I have a brand new MacBook Pro i7, 8GB, 7200 internal drive. I installed everything from a fresh install of Snow Leopard. CS4 has never been installed on this Mac.
Any thoughts?

if you have 4GB RAM, the system would need about 1-2GB,
so if you quit all other apps and only run PS, it has 2-3GB RAM left.
you can set RAM-usage in percentage, in the settings menu of photoshop,
i set it to 70%, the rest is for osx.
so lets say PS uses 2GB RAM in your case, the more hires images you open at once and the more layers they have,
and the bigger they are, the 2GB RAM are gone and PS will use the scratch disc for the mentioned images you opened at once, which is also configured in the settings menu. usage of a scratch disc (PS writes data to the scratch disc permanently) will slow down overall performance, it may lagg and everything is slower than before (in my experience). best for scratch disc usage is a separate, fast, internal disc, as huge as possible (50-250GB discsize and empty, no files on it, so that PS can write continously, in order to avoid disc-fragmentation, which would slow down the writing process additionally)
thats the reason i would add 8GB RAM.
RAM is very important for photoshop CS5.
(also processor clock speed and number of cores - in the moment 2 cores are enough
as CS5 isnt optimized yet for more than 4 or 6 cores. more to come soon, i hope...
in my case, i added 24GB RAM, cause i want to avoid usage of a scratch disc at all. this is a huge gain of performance for myself.
i never liked my old scratch disc, as working was terrible slow with it. i also had only 4GB RAM in my last mac, and working was no fun
i work on large format files, 50-100cm at 300dpi and lots of layers, each layer has to be seen like an image itself, so each layer rises RAM consumption.
its a pitty that i never saw adobe delivering some kind of performance guide for photoshop, how to improve performance for professional users, like posting that guide on their main photoshop site, i had to digg for these informations for a long period of time and found it in the end at diglloyd´s comprehensive site. i wonder why adobe makes a secret about photoshop performance, a lot of my friends at work mentioned formerly, that they have had huge lag issues and dont know where to begin solving these problems, which are solvable for sure.... (new hardware, proper settings and so on)
you can read detailed instructions, on how to speed up things in PS here: (where i took it for myself)

Photoshop suddenly very slow

Can't crop pictures. Too slow. Both desktop and laptop are doing same thing.
Rcently installed CS6 on two machines.
All updates installed.
No viruses detected.
Laptop - Windows 8/CS6 8GB RAM
Desktop - Windows 7/CS6 8GB RAM
When I crop a photo the task just hangs. The green progress bar hardly moves.
There never used to be a progress bar when I cropped a photo. It just cropped the photo, real fast.
Adobe Customer Service not very helpful so far.

Photoshop CS5 Very Slow Liquify

I've noticed that in Photoshop CS5, Liquify just works terribly slowly. When I click and drag to distort an image, the image gets distorted sometimes even 10 seconds after I've lifted my hand. Sometimes I have to wait 30-40 seconds for the distortions to happen before I can regain control of Photoshop.
Also, panning is a bit more choppy than in CS4, which annoys me a lot, as it was the case with CS4 compared to CS3, etc... I predict that panning in CS7 will look like a slideshow.
And another thing, when you Flick-Pan, and release the mouse, the canvas flies across the screen, and during that flying animation, in CS4, you could still zoom in and out with the keyboard. In CS5, you have to wait until the canvas has slowed down to a stop to be able to zoom. This is also a strange feature.
Adobe said CS5 will have performance improvements, and I can see filters, adjustments and brushes perform a tiny bit better, but basic things like panning, zooming and liquify got MUCH worse and less responsive, and this is not worth the tradeoff for me, since I use these features very frequently, many times a second.
I use a Wacom Bamboo Fun tablet most of the time, and I noticed that Liquify is much faster (although still too slow for me to use it) when I use my trackpad instead of the pen.
I'm using the Photoshop CS5 trial now, and I have Photoshop CS3 and CS4 both installed on the same computer, so I can tell that CS3 ran much faster, CS4 was a bit slower and CS5 is a LOT slower. I'm using a late 2008 15 inch Unibody MacBook Pro with 9600M / 9400M graphics, 4GB RAM and 2.53 GHz CPU, and speed gets a bit better when using the 9600M.
Here are my questions:
Has anyone else had any of these problems, especially Liquify?
Has anyone else used CS5 and noticed that Liquify runs just fine?
Does anyone have any suggestions of what I could try to cure any of these problems?
Is it possible that this is the way Photoshop CS5 should run on my computer, due to my hardware limitations and bloated software?

How long is it going to take to fix this liquify problem?? Come one guys I need it to work now and better than in CS4 not worse!!! Otherwise why did I spend almost 1K to upgrade???
Looking into the problem isn't enough!!! I need a solution since I use the liquify tool for almost 99.9% of my images (fashion/beauty photography retouching).
Is there a temporary fix??? using the CS4 liquify plugin into the CS5 software?????
do a google search on slow liquify and see what comes up..... still pretty nice and insecure requests for the reason why it is so slow because users think it is their machine (computer) but if I don't get an answer and fi very soon (couple of days at the most) this nice and insecurity will vanish for a HUGE ADOBE *** kicking campaign !!! Since photoshop is known for their arrogantly slow updates for their software and waits till the next big update to correct things....I am not going to wait 18 months for you guys to fix the liquify problem!!!
SO GET TO IT NOW!!!!! So I can do my work and make enough money to keep spending on adobe upgrades!
And as a side note...didn't you "wizzards" have enough time to discover this BIG problem beforehand?? Or were you to busy fighting with Apple about your huge Flash problem??

Installing RAM fixed my *very* slow Mountain Lion

I recognize this isn't really a practical "fix" for many people but I just wanted to share my experience.
Bought a new Mid-2012 15" MBP (2.3 GHz i7 with 4GB RAM) with Mountain Lion installed direct from Apple, set it up by migrating my accounts, data, etc. from an older MBP running Lion. I was very disappointed with how appallingly slow everything was, particularly when logging in, switching user accounts, and Safari. It was all just crawling crawling along. My plan all along was to upgrade the RAM anyway so I installed 8GB and now.........
My cold boot went from 80 seconds down to 48, and my user account login from the main screen went from 35 seconds down to 8! Switching accounts also is now almost instant, 1-2 seconds as opposed to a grey screen as it transitioned for anywhere from 15-20 seconds previously.Safari is also now zipping along.
I don't know if something else resets or updates when you add RAM, or if all the difference can just be attributed to the additional RAM, but the difference has been HUGE! Much much more than I was expecting. I also don't know how much of my problem was related to migrating my data with all its possible conflicts and left over bits and pieces from 3+ years of use.

I'm using a 2.97GHz i7 with 8GB RAM and the problem still exists. Its a shame really, I've been using windows via bootcamp for months and was just starting to like OSX again....

Photoshop performance very slow using keyboard move + nudge

I have a small file (24mb), that has a lot of layers. All of a sudden, moving a simple element (vector shape line layer, for example) takes 3-4 seconds to move 10px from the time of the keyboard press. This is very laggy, and frustratingly slow. New PS docs seem to be fine. My history and cache is set to tall and thin.
This feels exactly like a very old problem Photoshop had back in CS6. My last version of PS 2014 seemed fine.
I have a late 2013 Retina MacBook Pro, 16gb of ram, SSD drive with 80% free space.
Any ideas?

Hi Chris. So no suggestions? The file is 35mb. Photoshop says it is running at 100% efficiency. Moving any element is via command + arrow keys is painfully slow. 3-5 seconds to complete before you can move again. Layer previews are turned off. Impossible to work like this.
Michael
