title: php doing curl in loop will slow down server?
body: <p>If I have a loop with a lot of curl executions happening, will that slow down the server that is running that process? I realize that when this process runs, and I open a new tab to access some other page on the website, it doesn't load until this curl process that's happening finishes, is there a way for this process to run without interfering with the performance of the site?</p>
  
  <p>For example this is what I'm doing:</p>
  
  <pre><code>foreach ($chs as $ch) {
      $content = curl_exec($ch);
      ... do random stuff...
  }
  </code></pre>
  
  <p>I know I can do multi curl, but for the purposes of what I'm doing, I need to do it like this.</p>
  
  <p><strong>Edit:</strong></p>
  
  <p>Okay, maybe this might change things a bit but I actually want this process to run using WordPress cron. If this is running as a WordPress "cron", would it hinder the page performance of the WordPress site? So in essence, if the process is running, and people try to access the site, will they be lagged up?</p>
