Wade Arnold comes with some very good news for us that use Zend_Amf, he writes; Mark Reidenbach from everytruckjob.com has submitted a awesome patch for Zend Amf that creates a huge performance increase. Thanks so much Mark! I have also added a reference check optimization that uses SPL_object_hash to quickly see if an object has been seen before or not. Overall you should see a big performance increase. The test case I used was the James Ward’s census data from my ZendCon talk which consists of random people objects ranging from 1 – 100 duplicates totaling 5k total rows. Xdebug profiling analyzed by KCacheGrind showed roughly a 10X increase in performance!
The question is did all of these changes introduce any bugs? I have not been able to find anything and all of the tests pass. However with such a major change I would really appreciate you downloading the attached file and overwriting Zend/Amf/* with it’s contents. Please report any issues in the comments here or better yet on the actual bug ZF-7493 If all goes well we will try and get this into the 1.10 release.
