Last week, we posted some data from developers who have been seeing very slow performance with basic parts of Facebook’s new Graph API with the latest version of Facebook’s PHP SDK. Since then, Facebook has let us know that they are working on resolving the problems, and yesterday Facebook Platform engineer Naitik Shah let us know that he has committed a fix to the Facebook PHP SDK that addresses a key issue slowing the SDK down.

According to Naitik:

We found the key issue slowing the new SDK down, which seems to be related to curl handling the serialization. When we do the serialization ourselves, the issue does not manifest itself. It’s fixed in v2.0.5 of the SDK. Here’s the change: [link].

This means developers interested in using the new Graph APIs should see some meaningful performance improvements. Before the fix, basic FQL functions were taking many seconds.
