We're using the Magento SOAP v2 API with WS-I.

The problem is, that the SOAP calls are extremly slow (7-10 seconds per product!). We're calling catalogProductUpdate without images. The shop itself runs fine, just the SOAP call is slow. We activated the Cache and deaktivated the Index for performance boosting (that helpend on many other shops when the SOAP import was slow).

I put log-messages in various files to find out where it goes wrong. This is the combination log from function calls and dispatch events:

The interesting part is:

20.03.2013 14:17:43: Mage::run
20.03.2013 14:17:51: dispatchEvent: resource_get_tablename
...
20.03.2013 14:17:51: Mage_Core_Controller_Varien_Front

There are always 7-10 seconds between Mage::run and the next event/function call in Mage_Core_Controller_Varien_Front. Any ideas what can go wrong here?

We have the same problem with another shop (on another server, different customer) with the same settings, where an update takes 15 seconds.

  • Have you tried to debug config load times? That seems like most likely reason for a delay – Petar Dzhambazov Mar 20 '13 at 15:52
  • Could you please explain what you mean by "debug config load times"? – Anna Völkl Mar 20 '13 at 15:54
  • I guess Petar is talking about the time it takes to compile the config node tree. – Matthias Zeis Mar 20 '13 at 16:10
  • Yes, I mean time it takes to bootstrap Magento before actual request is processed. Also, why is Mage::run in the log at all? I do not see such call in api.php – Petar Dzhambazov Mar 20 '13 at 18:04
  • I've got a quick performance tip below, but if you/your developers are interested in getting elbows deep in the API, this API series covers the dispatch in detail and may help track down performance problems: alanstorm.com/category/magento#magento_api – Alan Storm Mar 20 '13 at 19:13

Do you have PHP setup to cache the WSDL files? PHP's SoapServer implementation (used by Magento) needs to examine the WSDL file at least once during a SOAP call, sometimes more than once. This can create exponential growth in your request times. Check the setting at

System -> Configuration -> Magento Core Api -> Enable WSDL Cache

and make sure its set to yes. This will instruct PHP to cache the WSDL file, which should improve your performance.

    I'm also working on the same project, so I know that yes, we have already enabled the WSDL cache. It made about 1 second difference but that's stil not at lot considering that the whole update call takes 8-10 seconds... – Daniel Lang Mar 20 '13 at 19:29
  • 2
    Right, Enable WSDL Cache in the Backend is set to "Yes". – Anna Völkl Mar 21 '13 at 8:56
  • Even though this was not the real solution, I select this answer to close the question. – Anna Völkl Apr 9 '13 at 11:29
  • This brought me from 30 seconds to do an update to 4 seconds. Win. – dgig May 2 '14 at 15:04
