OJS3: getRemoteDomain: Slow browsing

Software Support

Hi :slight_smile:
I’ve upgraded to OJS3 and every page build takes minutes!

I’ve created an slowlog and this function caused it:

	/**
	 * Get the remote domain of the current request
	 * @return string
	 */
	function getRemoteDomain() {
		$_this =& PKPRequest::_checkThis();

		static $remoteDomain;
		if (!isset($remoteDomain)) {
			$remoteDomain = null;
			$remoteDomain = @getHostByAddr($_this->getRemoteAddr());
			HookRegistry::call('Request::getRemoteDomain', array(&$remoteDomain));
		}
		return $remoteDomain;
	}

Why does OJS need this? Is there a way to disable this?

My slowlog:

Thanks in advance :wink:

Hi @Commifreak,

Does some of your content require a subscription to access it? OJS 3.0.x doesn’t support subscriptions (including domain-based authorization) but some of the back-end code is in place to check access. It may be that your content’s access configuration is set in a way that triggers the domain checking code in preparation for access control checking.
