Adobe Reader Speed Launch、Adobe Reader Synchronizer

Adobe为了加快程序的打开速度，在开机时预加了一个叫Speed Launch的软件

貌似又一个花而不实的功能：好象是什么同步之类的，没有看懂。具体看下边：

The Adobe SynchronizerAdobe Acrobat 8 and Reader 8 ship with a helper application called the Adobe Synchronizer. Synchronizer is a small application that runs in the background, providing synchronization of document reviews and Tracker subscriptions so that your data is available when you need it. On OS X, the process is called AdobeResourceSynchronizer and on Windows, it's called AdobeCollabSync.exe.

Platform	Process Name	Startup Method
Windows	AdobeCollabSync.exe	Startup Menu
OS X	AdobeResourceSynchronizer	Login Item

UPDATE: Removing the OS X Login Item is a little tricky because the Self Heal code that repairs the Reader install puts it back. See the note at the bottom of this post about how to disable self heal for this part of the install.
When does it run? One of the design goals of Synchronizer was to make it as unobtrusive as possible for users especially when it is not needed.

• Synchronizer runs briefly on user login - if there is nothing to synchronize then it will exit immediatly.
• Synchronizer will run in the background if you are participating in a Shared Review or add a subscription to the Tracker.
• Synchronizer runs while Acrobat or Reader runs if you participate in a Shared Review or use specific features such as the Reviewing preferences panel or Tracker.
• Synchronizer will not run if you remove all Shared Reviews and subscriptions from the Tracker.

What does it do?The Adobe Synchronizer is a networking agent that is used to build disconnection tolerant applications. The Synchronizer provides a local copy of data on a server so that applications can utilize it regardless of network connectivity. As data changes on the server, Synchronizer updates the local copy and as the user publishes changes made locally, Synchronizer makes the modifications to the server. If the client is disconnected from the network, Synchronizer will continue trying.

• Shared Review Workflows - Synchronizer sends and receives document comments and metadata in an XML file format (RSS 2.0 with some extensions) to a shared review location - either a Network Folder, a Sharepoint workspace, or WebDAV server.
• Review Tracker Subscriptions - The Synchronizer fetches any RSS / ATOM subscriptions that you add through the Review Tracker including attachments (such as in a PDFCast).

Where is the Synchronizer data stored?Synchronizer stores a local copy of the data in your Acrobat user data directoryusing a combination of a small database (SQLite) and the filesystem. On Windows, data is stored here:
C:\Documents and Settings\<USERNAME>\Application Data\Adobe\Acrobat\8.0\Synchronizer On OS X, this is:
~/Library/Acrobat User Data/8.0_<ppc or x86>/Synchronizer How do I make the Synchronizer Stop Synchronizing?Synchronizer will no longer synchronize shared reviews or subscriptions once they are removed from Tracker. Once there is nothing to synchronize, it will no longer run in the background.
Stop Tracking Shared ReviewsTo stop tracking a Shared Review, open the Review Tracker ("Comments->Review Tracker" menu). Click on the first tab item in the left-hand tab pane. Right click on the document that you no longer wish to track and select "Remove From Review Tracker". If you want to resume tracking the review, just open the shared review document again.

Removing a Subscription To remove a subscription, open the Review Tracker ("Comments->Review Tracker" menu). Click on the "RSS" tab in the left pane. Right click on the feed you'd like to unsubscribe from and choose "Remove"

Remember, removing all RSS feeds and Reviews from the Review Tracker will cause Synchronizer to stop the next time you quit Acrobat or Reader. Alternatively, you can delete all of the folders described above to accomplish the same thing. IMPORTANT - this DELETES all of your local Review and RSS data. It is a permanent operation that cannot be undone.
UPDATE - Removing the OS X LoginItem permanentlyThings are a bit more complicated than we initially thought - if you remove the LoginItem the code that repairs the Reader install will put it back. Until this is fixed, here's how you can work around the issue. Note that this will prevent all synchronization of RSS and Review data using Synchronizer while Reader is not running. Also note that this is an unsupported work-around, so you're mileage may vary. Please backup the file we're modifying before you edit it!

• Close Reader
• Navigate to /Library/Application Support/Adobe/Acrobat/ on your boot drive
• Back up the RdrENU80SelfHeal.xml file to some other place. (ENU refers to the English version of Reader so it may be a different name if you are using a non-english version)
• Open the RdrENU80SelfHeal.xml file in a text editor
• Search for AdobeResourceSynchronizer.app. You should see a section that looks like:
  <key>from</key>
  <string>Contents/Support/AdobeResourceSynchronizer.app</string>
  <key>isappassociated</key>
  <false/>
  <key>iscolorprofile</key>
  <false/>
  <key>isinstalled</key>
  <true/>
  <key>isloginitem</key>
  <true/>
  
• On the line after <key>isloginitem</key>, change <true/> to <false/>.
• Save the file
• Remove the login item from the Accounts System Preferences
• Launch Reader. You should no longer have the login item added on restart of Adobe Reader.

好像没有啥太大作用

同感，觉得没什么用处

其实是垃圾,现在的cpu都跑的很快,用不着

个人认为用处不大，我一般都是禁掉。
