Run the application faster with Run Query at Start


Run the application faster with Run Query at Start

seems to work fine When the application runs, multiple queries run. , Don't load the entire table into memory:
code :
var query = db.Schools.ToList();
txtScCount.Text = query.Count().ToString();
txtScCount.Text = db.Schools.Count().ToString();
catch (Exception)
{
}

it fixes the issue , Try this
code :
$contain = array('Comment');

$posts = $this->Post->find('all', array('contain'=>$contain));

$posts_with_comments = array_filter($posts, 'ten_or_more');
uasort($posts_with_comments, 'order_by_comment_count');    

$this->set('postsWithmostComments',$posts_with_comments);

function order_by_comment_count($a, $b) {
    if (count($a['Comment'] == $b['Comment']) 
       return 0;
    return ($a['Comment'] < $b['Comment']) ? -1 : 1;
}

function ten_or_more($post) {
   return (count($post['Comment']) >= 10);
}

Are you sure there isn't any API that provides the Google Play version much faster?

Any of those help I need a timer for a game I am building and what it basically does is fire up an event that moves and object a square every second when I hit play. Now either I let the game take its course(the game finishes or the object moves out of bounds) or press play once again, the timer seems to be triggering the object to move faster than previously and so on, going faster and faster every time I restart the time. ,
but I can see the arrow moving faster and faster every time.

wish help you to fix your issue Try the following, which eliminates your count(*) and instead uses exists.
code :
 with dupe as ( 
   select id, 
     json_document->'Firstname'->0->'Content' as first_name, 
     json_document->'Lastname'->0->'Content' as last_name, 
     identifiers->'RecordID' as record_id 
   from 
     (select 
       *, 
       jsonb_array_elements(json_document->'Identifiers') as identifiers 
      from staging ) sub 
      group by
        id,
        record_id, 
        json_document 
      order by last_name ) 
 select * from dupe da 
   where exists 
     (select * 
       from dupe db 
       where 
         db.record_id = da.record_id 
         and db.id != da.id
     )

Any of those help Given an array having .length 100 containing elements having values 0 to 99 at the respective indexes, where the requirement is to find element of of array equal to n : 51. , The answer is pretty obvious:
More operations take more time.
code :
               |  forwards  | forwards and backwards
---------------+------------+------------------------
>=/===/<       |       100  |                   200
++/--          |        50  |                   100
a[b]           |        50  |                   100
&&/||/if/for   |       100  |                   200
