title: Improving Performance on massive IndexedDB Insert
body: <p>We are trying to pre-cache a large sum of data on load of our web application into indexed db. From my performance testing the speed is decent on a desktop browser (e.g. Internet Explorer) where I can insert 10,000 records in around 2 seconds. But comparing the exact same functionality on the iPad it drops to 30 seconds. That comparison just blew my mind.</p>
  
  <p>Does anyone know of any hints or tricks to inserting large data sets into indexedDB. I dont know if it is possible at all but if we could build up a copy of an indexedDB server side with all the data prepopulated and then just shoot it over to the client and it just stores it down to the browser. Is anything along these lines doable? </p>
  
  <p>Thanks</p>
