Yes, Zend_Json is slower than ext/json, even when it proxies directly to ext/json. That said, there are a number of situations where you might wish to use Zend_Json over ext/json:
* If you have to encode JS lambdas as JSON * If you want support for additional charset encodings Finally, for most datasets developers will utilize, the amount of time spent in de/serialization is negligible -- if you're working on datasets of 100k+ items, you're likely doing something wrong anyways. -- whisher <[email protected]> wrote (on Friday, 10 December 2010, 08:44 AM -0800): > > $memoryNativeStart = memory_get_peak_usage (true); > > $start = microtime( true ); > > $native = json_decode(json_encode( $data )); > > $memoryNative = memory_get_peak_usage (true) - $memoryNativeStart; > > $jsonNativeTime = microtime( true ) - $start; > > $msgNative = 'Native php > '; > > $msgNative .= 'time '.$jsonNativeTime.' memory '.$memoryNative.' > '; > > echo $msgNative; > > sleep(3); > > $memoryZendStart = memory_get_peak_usage (true); > > $start = microtime( true ); > > $zend = Zend_Json::decode(Zend_Json::encode( $data )); > > $memoryZend = memory_get_peak_usage (true) - $memoryZendStart; > > $jsonZendTime = microtime( true ) - $start; > > $msgZend = 'Zend > '; > > $msgZend .= 'time '.$jsonZendTime.' memory '.$memoryZend; > > echo $msgZend; > > inside data there is about 130,000 records (with a result set) > > I get > > Native php > > time 2.24236011505 memory 158072832 > > Zend > > time 3.50552582741 memory 109051904 > -- > View this message in context: > http://zend-framework-community.634137.n4.nabble.com/json-encode-json-decode-vs-Zend-Json-encode-Zend-Json-decode-tp3080647p3082295.html > Sent from the Zend Framework mailing list archive at Nabble.com. > -- Matthew Weier O'Phinney Project Lead | [email protected] Zend Framework | http://framework.zend.com/ PGP key: http://framework.zend.com/zf-matthew-pgp-key.asc
