title: myslqimport --use-threads
body: <p>I have a large database I'm copying to a slave server.  Trying to import it (about 15GB) via a regular mysqldump took 2 days and failed.  So I'm trying the mysqldump --tab trick.</p>
  
  <p>I also want to import using --use-threads - but it doesn't seem to be doing multiple tables at once.  Is there any way to tell if it's even working?</p>
  
  <pre><code>mysqldump --single-transaction --quick --hex-blob --master-data=1 --tab=/tmp/backup/ apm
  </code></pre>
  
  <p>on slave:</p>
  
  <pre><code>cat *.sql | mysql apm
  mysqlimport --lock-tables --use-threads=4 apm /tmp/backup/*.txt
  </code></pre>
  
  <p>Also: Any idea how to disable binlog without editing the conf file and restarting the server?  Seems kinda dumb &amp; slow that mysql's copying all the data into the binlog again too.</p>
