InDesign 5.5 scrolling very slow on Macbook Pro

Hi,
I am using InDesign CS 5.5 (7.5.3) on a Macbook Pro - 2.4 Ghz Intel Core i7 w/ 8GB Ram and a 250GB SSD and AMD Radeon HD 6770M graphic card - and it's incredibly slow when scrolling up and down in a document. Admittedly that document has lots of big tifs embedded but still it feels very slow and often hangs on the spinning wheel. I've tried a helper app to switch the graphic cards and have also turned preflight off and set live screen drawing to delayed after reading some threads on here. It's especially bad when I come from another application but doesn't seem to make a difference how many other apps are open. Is this normal? Does anyone have any ideas how to improve performance?
Thanks
Maak

What about the display perfomance ?
Go to View-->Diaply performance, set it to Fast or Typical.
Here are few link that could help :-

VERY SLOW, LAGS & FREEZES!!

Just got the phone I like it but it is very slow! is BB coming out with a software update or something to fix this soon?

I have noticed that during data intensive tasks (Viigo update), it will slow a lil bit
Other than that, I dont see the lag. maybe you are clicking on an icon too much and opening it up twice but relly canceling it and opening it up.

Very Slow / Lag When Screen Moves...

Hi Guys,
I’m really a newbie when it comes to AS3 – so really a total newbie when it comes to using it to develop iPhone games/apps, but I have used AS2 for years now
I’ve been trying to do a simple test – Just use mouse events to move a screen around depending on what is pressed. No Characters/hittests/etc.
What I have created works great on my pc – very smooth, and even on the iphone, the controls work as expected – but the problem is how SLOW everything is running. Pressing the "UP" arrow - makes the screen move, but very SLOW and Jumpy.
I have tried using onkeyframe and using a timer – but both are very slow.
Typically when I made games in AS2 – the “level” would just be a single BIG movieclip – as shown in “Example A” – but this was very slow on the iphone, so I tried a tile based approach (“Example B”), which reuses the same movieclips, it just moves them and renames them – trying to cut memory usage down, only loading what is needed - but still its slow. The total size of the "level" is only about 3x bigger than the iphone visible screen.
I have made sure all variables are done correctly: var thisVar:int = 10; etc and have enabled cache as bitmap. I have replaced all vector graphics with jpegs, and followed the guide on how to optimize code for iphone development – but nothing seems to work, everything just lags as the screen moves/updates – but everything works great on my pc.
Can someone please explain what I am doing wrong? Is there a way to cache the whole map before the game loads? Which is the correct way to make an iphone game where the level is bigger than the default screen - tile based or a large level graphic.
Thanks so much for any help! I’ve been trying to get this simple test working for 3 days now – but documentation is limited at the moment.
Cheers!

This should be better:
the function addPage() is what I used to test Bitmaps
import flash.display.Shape;
import flash.display.Sprite;;
Multitouch.inputMode = MultitouchInputMode.GESTURE;
var currentGalleryItem:Number = 1;
var totalGalleryItems:Number = 4;
var slideCounter:Number = 0;
var gallery_items:Sprite = new Sprite();
addChild(gallery_items);
addPages();
stage.addEventListener (TransformGestureEvent.GESTURE_SWIPE, fl_SwipeToGoToNextPreviousFrame);
// create pages
function addPages():void
addShape(0, 0, 0xff0000);
addShape(768, 0, 0x00ff00);
addShape(1536, 0, 0x0000ff);
function addPage(xPos:Number, yPos:Number):void
var p:Bitmap = new Bitmap(new bookPage());
p.x = xPos;
p.y = yPos;
gallery_items.addChild(p);
function addShape(xPos:Number, yPos:Number, col:uint):void
var s:Shape = new Shape();
s.graphics.beginFill(col);
s.graphics.drawRect(xPos, yPos, 768, 1028);
s.graphics.endFill();
gallery_items.addChild(s);
function fl_SwipeToGoToNextPreviousFrame(event:TransformGestureEvent):void
if(event.offsetX == 1)
if(currentGalleryItem > 1){
currentGalleryItem--;
slideRight();
else if(event.offsetX == -1)
if(currentGalleryItem < totalGalleryItems){
currentGalleryItem++;
slideLeft();
function slideLeft(){
gallery_items.addEventListener("enterFrame", moveGalleryLeft);
function slideRight(){
gallery_items.addEventListener("enterFrame", moveGalleryRight);
function moveGalleryLeft(evt:Event){
gallery_items.x -= 76.8;
slideCounter++;
if(slideCounter == 10){
gallery_items.removeEventListener("enterFrame", moveGalleryLeft);
slideCounter = 0;
function moveGalleryRight(evt:Event){
gallery_items.x += 76.8;
slideCounter++;
if(slideCounter == 10){
gallery_items.removeEventListener("enterFrame", moveGalleryRight);
slideCounter = 0;

Converting .docx merges to PDF is very slow.

Hi all first post, so hello!
As the thread question states, I am trying to figure out creating PDFs from docx merges are very very slow to complete. We are using Adobe Acrobat 8, and Microsoft Word 2007 on Windows XP.
Before we upgraded to MS Office 2007 and the docx format, Acrobat 8 created PDF merges in the the 2003 .doc format just fine and was very quick. We can even created PDFs from .doc merges through Office 2007 and it is still works great and is super fast. But once we try a creating a PDF from a .docx merge, it crawls and is very slow, and is starting to be time consuming for the users. I checked out the 3-4 people that perform this function, and they all seem to have the same issue. So i would guess this would have something to do with the .docx format and the way Adobe 8 interprets the format to create a PDF from it. The documents normally fall within the 1200-1500 page range.
Acrobat 8 has been updated with the latest program updates, but I am a loss as to why .doc's create so fast, but docx's are very very slow.
Any input would be greatly appreciated. I tried to include all pertinent info you would need, if I left something out, please let me know.
Thanks!

Bookmarking some pdf is very slow

I found the bookmarking action for some pdf in Sony T1 is very slow. It could take about 30 seconds before the bookmark triangle appears. With epub book it only take about 2 seconds.
Press back to return to booklist then open the book again may make it looks more responsive.
The pdf I was reading is a text based pdf with some chinese fonts embeded, no cropped view, just in regular view.

Hello,
Thank you for your post.
PDF files have everything embedded, such as the Text font, pictures, and file structure therefore it takes longer to read the file prior to marking it. this is why you can read a PDF with Chinese fonts, but cannot read an Epub Book with Chinese characters.

Building PDF file very slow when pmd file contains many eps files

I have a 64 page publication which contains a placed .eps file on each page. (The .eps files are the output of a music notation program and average about 60KB).   I have a new computer with a fast quad pentium processor. It takes 10 minutes to export a pdf file (It took 45 minutes on my old computer!).
The time is spent in the first phase, where the little window says "Sending page 1,2...etc. The pages crawl by. PageMaker is CPU bound.
PDF export option or distiller settings appear to have little affect on this.
It was my understanding that eps files, ps files, and pdf files are all similar in structure. What is taking so long here?
10 minutes is not a lot in the scheme of things right now but this is part of a much bigger book and I am concerend about how much time this process is going to take when we are up to 600 pages.

Well if you don't know, I doubly don't know.
I looked at that lon g list of possible reasons for the Courier substitution, and most or all of them don't seem to apply. I have no PostScript printer, just an inkjet for drafts. We NEVER print from PageMaker for any of our work. We make PDFs. We either print the PDFs here for draft work, or send them out to the printer when we are done.   All the fonts involved are TT fonts. Whe n I make a .ps file I use PrinterStyles->Acrobat, and actually I've only been doing that to investigate this performance problem to isola te what phase of the process is slow.   Normally I just use the PageMaker Export PDF function and it has worked fine with many customers, many publications, over 10 years.
I'm going to try to fiddle with some of these embedding options to see what arises.
It is suspicious that posting this problem in the Sibelius forum elicits no response. This cannot be an uncommon workflow in music publishing - use PageMaker for the book framework and place Sibelius scores when needed.   Any kind of music textbook would have this flow.
Do you by any chance know the algorithm for locating fonts when some are referenced and/or imbedded in placed .eps files, and others, possible duplicates, are referenced by the PageMaker document. Understanding that would be the key to unlocking this puzzle.
Also Jay Chevako asked for the .pdf files. I will get around to that when I can, I'm not sure what you will infer - the first one will be correct but slow to export and the second will be fast but with the Courier substitution.
Thanks

Web pages containing flash run/scroll very slow, help plz

hi guys,
complete first timer on here so be gentle,
i have a very annoying problem with flash player and my
firefox web browser.
what happens is,
normal browsing is all ok with no problems, but as soon as a
flash ad or anything with flash appears , it basically brings that
web page to a stand still.
meaning, you know when you use your scroll wheel under normal
circumstances, to scroll down a page, well when the problem
happens, the page just virtually freezes up, and scrolling just
becomes impossible.
i figured this out to be a flash player problem, when i was
on IGN'S web site, and they have small ads appearing at regular
intervals, and i noticed that as soon as ads appeared, the
scrolling problem happened.
so can anybody give me any ideas as to why or how to stop
this happening.
i have firefox 2.0.0.3 and flash player 9,0,28,0
thanks for any help.

aghh right,
basically on both the links above, i have no problems,
my problems are whenever there is flash ads or flash movie
streams, my scrolling is so bad, i have to go back to the old
fashion drag the bar.
i did actually think i had cured it with a reinstall of flash
player, but its back again.
as much as it pains me to say this....iam real tempted to go
back to the dreaded I.E.
as my main interests are gaming, virtually all my sites i
visit are every flash orientated, so to be honest, i dont know what
to do.
one thing for sure its dam annoying.

Export to PDF is very slow

Hi all,
I am using the following script to export an indd document to PDF file. But the process takes long time. Is there any configurations that can be made to reduce the processing time.
app.documents.item(0).exportFile(ExportFormat.pdfType,File(<pdfFileName>),app.pdfExportPre sets.item("[Press Quality]"));
Please provide me some way to reduce the processing time taken for exporting PDF.
Thanks,
Anitha

Tiago,
For exporting Discoverer has to bring all the data into memory, format it and then export it to the client. It does not use the data cache, so possibly you are running low on memory and your swap/disk is being used -- something to check
For Discoverer 10g Desktop, the aggregation registry keys are not there by default so that could also cause a slow export and cpu utilization if you have aggregation. See MetaLink document 313444.1 -- it may apply to 9.0.4 as well
SS,
You have not provided which component you are exporting from (Desktop, Plus, Viewer) and the versions. There could be several possibilities depending upon the component and the version. The above also applies.
I also recall and issue with spanish office 2003 in some prior versions -- not sure if that applies to your situation(s)

Print to PDF is very slow showing "save as" dialog when printing from Outlook 2013

Hello,
I'm having a problem with one of my users. The problem is intermittent. At first when I was looking at the issue, here is what I saw:
In Outlook 2013, I opened an e-mail. I then selected Print, selected the Adobe PDF printer, and hit the print button. There was over a 1 minute delay before the "save as" dialog appeared to ask me where to save the document and what to name it. I did this for several different e-mails with and without attachments and the problem was consistent. I saved the e-mail to a local e-mail file and the problem was the same. This process was over 30 or 40 minutes. I was pulled away for another issue and now the "save as" dialog pops up within seconds. The user is complaining that this happens regularly. I tried a repair, cleared temp files, and was going to try printing from other apps, but then it started temporarily behaving itself, so I can't tell you if the same delay existed in other apps. I didn't see anything obvious in the event viewer logs.
Has anyone else seen this? Anyone have an idea on how to troubleshoot this?
Thanks,
Jeffery Smith

Thank for your help Bill, but changing settings in the distiller did not seem to work. As my application prints directly to the default application without using anything specific to Acrobat, I was hoping there was a simple way forward. A colleague suggested copying registry entries from the account I logged on as to the S-1-5-18 entry, then rebooting. This had no effect as the prompt still comes up.
Aandi, I don't have the Acrobat SDK or any experience of it.
Also I'm not sure where any code/script would sit since the application is stable and so I would rather not change it.
If it amounts to a few lines of javascript sitting outside the application then that would be of interest.

Slow PDF Scrolling

On my 15" rMBP, my PDFs are very slow to scroll. It will be the only PDF open and I have open each file in it's own window checked.
Any help will be appreciated!

Back up all data. Quit Preview if it's running.
Hold down the option key and select Go ▹ Library from the Finder menu bar. From the Library folder, delete the following items, if they exist:
Caches/com.apple.Preview
Containers/com.apple.Preview
Preferences/com.apple.Preview.LSSharedFileList.plist

Launch the application and test.

Musca scrolling webpage is very slow and a little freezing

Hi guys !
I installed Musca on yaourt ,my os is x86_64,
when I scrolled in firefox ,the web page scrolled very slow and with some freezing.:(
but the termial (urxvt) and other apps was working without this problem.
my video driver is x86_video_radeonhd ,
my video card is ATI HD3650.
when I use fvwm ,all things works well!
thanks for your help!!!:D

Hi, I see you're pretty new to the forums. Unfortunately, I don't know what could be causing your problem. So, let me first direct you to the thread about musca here. You may also want to look at the ATI thread (no idea). Have you tried enabling/disenabling compositing?
Secondly, let me direct you to the Forum Etiquette guide, especially the part about bumping. Usually you should only "bump" your thread after 3-5 days and after you have tried more, researched more, and only to tell us any new information you have, like "XYZ doesn't help either, it makes Firefox segfault."

PDF Scrolling in Safari

Pdfs scroll very badly in Safari. It is jerky, very sensitive, too fast. This has come up before in the Communities, but the solutions I've found either don't work or aren't relevant after OSX updates. In preview scrolling is well behaved. Any update solutions?
I am using a Magic Mouse on an iMac running OSX 10.9.1, Safari Version 7.0.1 (9537.73.11).
Same problem on a MBP (same setup).
Thanks

Back up all data before making any changes. Please take each of the following steps until the problem is resolved.
Step 1
If Adobe Reader or Acrobat is installed, and the problem is just that you can't print PDF's displayed in Safari, you may be able to print by moving the cursor to the the bottom edge of the page, somewhere near the middle. A black toolbar may appear under the cursor. Click the printer icon.
Step 2
There should be a setting in its preferences of the Adobe application such as Display PDF in Browser. I don't use those applications myself, so I can't be more precise. Deselect that setting, if it's selected.
Step 3
If you get a message such as ""Adobe Reader blocked for this website," then from the Safari menu bar, select
Safari ▹ Preferences... ▹ Security
and check the box marked
Allow Plug-ins
Then click
Manage Website Settings...
and make any required changes to the security settings for the Adobe PDF plugin.
Step 4
Triple-click anywhere in the line of text below on this page to select it, the copy the selected text to the Clipboard by pressing the key combination command-C:
/Library/Internet Plug-ins
In the Finder, select
Go ▹ Go to Folder
from the menu bar, or press the key combination shift-command-G. Paste into the text box that opens (command-V), then press return.
From the folder that opens, move to the Trash any items that have "Adobe" or “PDF” in the name. You may be prompted for your login password. Then quit and relaunch Safari.
Step 5
The "Silverlight" web plugin distributed by Microsoft can interfere with PDF display in Safari, so you may need to remove it, if it's present. The same goes for a plugin called "iGetter," and perhaps others — I don't have a complete list. Don't remove Silverlight if you use the "Netflix" video-streaming service.
Step 6
Do as in Step 4 with this line:
~/Library/Internet Plug-ins
If you don’t like the results of this procedure, restore the items from the backup you made before you started. Relaunch Safari.
