====== Thunderbird Performance ======

http://kb.mozillazine.org/Application_not_responding

===== Performance Enhancing Tips =====

==== Delete and Re-Create Mail Summary Files ====

  - Exit Thunderbird.
  - Find your profile folder.
  - Open the folder containing your stored messages.
  - Select the *.msf files and delete them.
  - Restart Thunderbird.
  - Wait for Thunderbird to recreate the mail summary file(s).

For example, if you are using the Global Inbox, this would be the ''Local Folders'' folder inside the ''Mail'' folder. Otherwise, it may be a folder named after the mail server inside the ''Mail'' or ''ImapMail'' folder. For example, "pop.gmail.com" if you're using gmail.

=== Linux ===

<file>
find ~/.thunderbird/*.default/ -name *.msf -exec rm -f {} \;
</file>

==== Expunge (compact) Folders ====

http://kb.mozillazine.org/Compacting_folders

=== Manually ===

Tools -> Account Settings -> Server Settings -> "When I delete a message"

In TB, select a top-level account on the left, then:

File -> Compact Folders

=== Automatically ===

Account Settings -> Server Settings -> Clean up ("Expunge") Inbox on Exit

Preferences -> Advanced -> Network & Disk Space -> "Compact folders when it will save over X MB"

  * The TB UI may 'hang' noticeably during expunge operations
  * Enable automatic expunging of all folders
    * Smaller numbers will cause TB to compact folders more often
    * Larger numbers will cause TB to compact folders less often
    * 20MB is the default
    * 1MB is often recommended

==== Turn Off Indexing ====

Preferences -> Advanced -> General -> Advanced Configuration -> Enable Global Search and Indexer

==== Turn Off Junk Filtering ====

Account Settings -> (each account) -> Junk Settings

Preferences -> Security -> Junk

''Reset Training Data'' can fix some problems and is global affecting all accounts.

===== Find the Cause of Hanging =====

Try using Process Monitor from Sysinternals to see what it's doing when it hangs.

Try using Safe Mode to disable all add-ons: http://kb.mozillazine.org/Safe_mode.

===== Move Mail Storage Folder Out of Roaming Profile =====

:!: The intent here is to speed up logon and logoff times.

:!: If you are on a Windows Domain network, implement **[[networking:windows:active_directory:folder_redirection|folder redirection]]** instead.
