You should insert all 20K records in single sqllite transaction.

Something like this:

    public static void AddOrUpdateTickRecords( ObservableCollection tickRecords )
        {
        // Create a new connection
        using ( var db = new SQLiteConnection( new SQLitePlatformWinRT(), DbPath ) )
            {
            db.BeginTransaction();
            try
                {
                foreach ( var tickRecord in tickRecords )
                    {
                    if ( tickRecord.Id == 0 )
                        {
                        // New
                        db.Insert( tickRecord );
                        }
                    else
                        {
                        // Update
                        db.Update( tickRecord );
                        }
                    }

                db.Commit();
                }
            catch ( Exception )
                {
                db.Rollback();
                }
            }
        }
