title: SQL Server on Azure has slowed to half speed
body: <p>We recently ran out space on a Azure database. After deleting a lot of unused tables, (none of which had indexes, or even keys,) Transact queries take almost exactly twice as long. SSIS imports seem to be completely unaffected.</p>
  
  <p>After the obvious step of shrinking the log file, I'm now totally baffled.</p>
  
  <p>Any advice would be greatly appreciated.</p>
