Quoting from the Wiki: http://wiki2.dovecot.org/Plugins/FTS/Squat

NOTE: The Squat code is quite slow for large mailboxes. There are also  
a few bugs that are unlikely to be fixed. In v2.1+ it's recommended to  
use fts-lucene instead.

So you should do what the wiki does suggest, either switching to  
Lucene or Solr.
