Upgrating yourls - shortest time to create new url

I'm thinking how to alter yourls to make new shorten urls faster. I don't really see where it is in the code, but when "yourls" is making new shorten url, it adds title to the database, so I assume that it has to open given url and parses it to get url. I don't need it and maybe it causes that short url creates slowly. I thought about making my own url shortener, but I am really out of time.

What do you think, is it anything that I can change in the yourls script, and where I can find in the code where it's searching it (i would just set title to "" constantly, cause this column can stay in the database for now).

If you just want a lightweight URL shortener, writing your own is probably the easiest way to go. Have a look at my super simple shortener script using DBM.

<?php

header('Content-Type: text/plain');

// Add url
if (isset($_GET['add'])) {
    $db = dba_open("/tmp/shortner.db", "c", "db4");
    if (!$db) trigger_error("dba_open failed", E_USER_ERROR);

    $key = substr(base_convert(md5($_GET['add']), 10, 36), 0, 5);
    dba_insert($key, $_GET['add'], $db);
    dba_close($db);

    echo "http://{$_SERVER['HTTP_HOST']}/$key";
    exit();
}

// Get url
$db = dba_open("/tmp/shortner.db", "r", "db4");
if (!$db) trigger_error("dba_open failed", E_USER_ERROR);

if (isset($_GET['key']) && dba_exists($_GET['key'], $db)) {
    $url = dba_fetch($_GET['key'], $db);
}
dba_close($db);

if (!isset($url)) {
    header("HTTP/1.0 404 Not Found");
    echo "Not found $_GET[key]";
    exit();
}

header("Location: $url");
echo $url;

With .htaccess

RewriteEngine On
RewriteRule ^(\w{5})$ /index.php?key=$1

You can easily add a hit counter if you need it, just before doing the direct. (In that case open the DB in 'w' mode).

Note that the key is based on a hash of the URL, so if the same URL is added again it just gets the same key (thus shortened URL).

Without actually doing a desc on the query that you are talking about I don't think you can assume that it's the problem. You'd need to profile the whole script to find where it's running slowly.
