    <p><strong>(IMPORTANT) EDIT 3:</strong> Running the testajax2.php by itself and NOT AJAX. The duration is about the same, 1.02-1.03s. So I guess that means the problem is in PHP-MYSQL or XAMPP?? When ran through phpmyadmin query, here's the result: Showing rows 0 - 29 ( ~50 total , Query took <strong>0.0015 sec</strong>). It appears the problem lies not in Ajax after all, but perhaps in PHP. Help please... (I've also just edited the question title.)</p> <p><strong>Answer:</strong> Add the following line in the hosts file located in <code>”C:\Windows\System32\drivers\etc”</code></p> <pre><code> 127.0.0.1 localhost </code></pre> <p><hr><hr> <em>The question before:</em> Is it normal for Jquery Ajax with sql queries on the other side have the <strong>minimum duration of 1 sec</strong>? I've tried <code>$.get</code>, <code>$.post</code>,<code>$.getjson</code>,<code>$.ajax({type:'POST'})</code>, <code>$.ajax({type:'GET'})</code>. As I've said, it's the minimum, it could get worse to about 3 sec even. I doubt it's the sql queries though, as when I try them in phpmyadmin, the results come up extremely fast.</p> <p>It doesn't matter also if the queries are very simple and the table only has 2 elements, it would still follow the 1 sec minimum. I'm using the latest XAMPP, and I don't know if it matters, but I'm accessing the files through localhost and 127.0.0.1. Thanks!</p> <p>EDIT: Thanks for the reply, guys. I'm running it on a local environment, on the same laptop I made these files on. Jquery is updated. The returned value/array is json_encoded. I'm using mysqli. The database is in InnoDB, and within are only about 5 tables, and there are hardly anything on them. Here's a very simple sample query:<br></p> <p><strong>index.php</strong></p> <pre><code> var test_id =2; testcall(); function testcall(){ $.ajax({ url: 'testajax2.php', type: 'POST', data: {test_id: test_id}, success: function(data){ } }); } </code></pre> <p><strong>testajax2.php</strong></p> <pre><code> $mysqli = new mysqli('localhost', 'root', '', 'testdb'); $mysqli-&gt;set_charset("utf8"); if(mysqli_connect_errno()) { echo "Connection Failed: " . mysqli_connect_errno(); exit(); } $testreceive = $_POST['test_id']; $query = "SELECT First_Name from tblperson"; $result = $mysqli-&gt;query($query); $row = $result-&gt;fetch_all(MYSQLI_ASSOC); echo json_encode($row); </code></pre> <p>The tblperson contains 50 records, and there are only 4 columns. According to Firebug, it took 1.03s to do that extremely simple task. I'm not sure what it really means, but viewing through Net tab in Firebug, the bar is entirely violet. 0 and 1.03s Waiting. +1.03s and 0 Receiving.</p> <p>EDIT 2: It also doesn't matter if I send them as <code>json_encode($row)</code> or <code>foreach($row as $value){ echo $value['First_Name']; }</code>. It would still be about at least 1 sec. I've tried on Chrome and Safari, and though I can't have the exact duration, I can tell that it's about the same. But for simple ajax call with NO SQL QUERIES. If I remember correctly, it's very fast. I'd be back with a sample and duration output.</p>

    1. COWe require more info, your context is too vague. Do you have a link where we can try it? How much ajax calls do you have simultaneously? Is your environment local or remote? ....

    3. COFor me / my setup this is not normal no.. locally my ajax requests (on average, according to firebug) are completed within 140ms. But as the other comment says.. we have no idea what's happening on your machine, how complex the scripts are.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
