Pasi Kallinen cb406f72b0 Bug 21288: Slowness in acquisition caused by GetInvoices ... The SQL query done by GetInvoices is quite slow on our production server, taking about a minute. In the query, there's this join: LEFT JOIN subscription ON biblio.biblionumber = subscription.biblionumber but there's no index on subscription.biblionumber. Adding the index speeds up the query so it only takes up about 3 seconds.
