Performance measurement and tuning
- 1. High performance websites An introduction into xDebug profiling, Kcachegrind and JMeter
- 2. About Us Axel Jung Timo Schmidt Software Developer Software Developer AOE media GmbH AOE media GmbH
- 3. Preparation Install Virtualbox and import the t3dd2012 appliance (User & Password: t3dd2012) You will find: • Apache with xdebug and apc • Jmeter • Kcachegrind • PHPStorm There are two vhost: • typo3.t3dd2012 and playground.t3dd2012
- 5. Can you build a new Yes, we can! website for me?
- 6. But I expect a lot of visitors. Can you handle them? Yes, we can!
- 8. ...after inventing the next, cutting edge, enterprise architecture...
- 9. ...and some* days of development...
- 10. The servers are not fast enough for your application ;)
- 12. Install XDebug & KCachegrind ● Install xdebug (eg. apt-get install php5-xdebug) ● Install kcachegrind (eg. apt-get install kcachegrind)
- 13. Configure xDebug ● Configuration in (/etc/php5/conf.d/xdebug.ini on Ubuntu) ● xdebug.profiler_enable_trigger = 1 ● xdebug.profiler_output_dir = /..
- 14. Profiling ● By request: ?XDEBUG_PROFILE ● All requests by htaccess: php_value xdebug.profiler_enable 1
- 16. KCachegrind OPTIMIZE WITH IDE AND MIND
- 17. Analyzing Cachegrinds ●High self / medium self and many calls => High potential for optimization ● Early in call graph & not needed => High potential for optimization
- 18. Hands on ● There is an extension „slowstock“ in the VM. ● Open: „http://typo3.t3dd2012/index.php?id=2“ and analyze it with kcachegrind.
- 20. Total Time Cost 12769352 This code is very time consuming
- 21. Change 1 (SoapConversionRateProvider) SoapClient is instantiated everytime => move to constructor
- 22. Change 1 (SoapConversionRateProvider) Before: /** * @param string $fromCurrency * @param string $toCurrency * @return float */ public function getConversionRate($fromCurrency, $toCurrency) { $converter = new SoapClient($this->wsdl); $in = new stdClass(); $in->FromCurrency = $fromCurrency; $in->ToCurrency = $toCurrency; $out = $converter->ConversionRate($in); $result = $out->ConversionRateResult; return $result; }
- 23. Change 1 (SoapConversionRateProvider) After: /** @var SoapClient */ protected $converter; /** @return void */ public function __construct() { $this->converter = new SoapClient($this->wsdl); } /** * @param string $fromCurrency * @param string $toCurrency * @return float */ public function getConversionRate($fromCurrency, $toCurrency) { $in = new stdClass(); $in->FromCurrency = $fromCurrency; $in->ToCurrency = $toCurrency; $out = $this->converter->ConversionRate($in); $result = $out->ConversionRateResult; return $result; }
- 24. Total Time Cost 10910560 ( ~ -15%) 11,99 % is still much time :(
- 25. Change 2 (SoapConversionRateProvider) ● Conversion rates can be cached in APC cache to reduce webservice calls. – Inject „ConversionRateCache“ into SoapConversionRateProvider. – Use the cache in the convert method.
- 26. Change 2 (SoapConversionRateProvider) Before: /** @var SoapClient */ protected $converter; /** @return void */ public function __construct() { $this->converter = new SoapClient($this->wsdl); } /** * @param string $fromCurrency * @param string $toCurrency * @return float */ public function getConversionRate($fromCurrency, $toCurrency) { $in = new stdClass(); $in->FromCurrency = $fromCurrency; $in->ToCurrency = $toCurrency; $out = $this->converter->ConversionRate($in); $result = $out->ConversionRateResult; return $result; }
- 27. Change 2 (SoapConversionRateProvider) After: /** @var Tx_Slowstock_System_Cache_ConversionRateCache */ protected $cache; ... /** @param Tx_Slowstock_System_Cache_ConversionRateCache $cache */ public function injectRateCache(Tx_Slowstock_System_Cache_ConversionRateCache $cache) { $this->cache = $cache; } … public function getConversionRate($fromCurrency, $toCurrency) { $cacheKey = $fromCurrency.'-'.$toCurrency; if(!$this->cache->has($cacheKey)) { $in = new stdClass(); $in->FromCurrency = $fromCurrency; $in->ToCurrency = $toCurrency; $out = $this->converter->ConversionRate($in); $result = $out->ConversionRateResult; $this->cache->set($cacheKey, $result); } return $this->cache->get($cacheKey); }
- 28. Change 2 (SoapConversionRateProvider) After: /** @var Tx_Slowstock_System_Cache_ConversionRateCache */ protected $cache; ... /** @param Tx_Slowstock_System_Cache_ConversionRateCache $cache */ public function injectRateCache(Tx_Slowstock_System_Cache_ConversionRateCache $cache) { $this->cache = $cache; } … public function getConversionRate($fromCurrency, $toCurrency) { $cacheKey = $fromCurrency.'-'.$toCurrency; if(!$this->cache->has($cacheKey)) { $in = new stdClass(); $in->FromCurrency = $fromCurrency; $in->ToCurrency = $toCurrency; $out = $this->converter->ConversionRate($in); $result = $out->ConversionRateResult; $this->cache->set($cacheKey, $result); } return $this->cache->get($cacheKey); }
- 29. Total Time Cost 5187627 ( ~ -50%) Much better, but let's look on the call graph... do we need all that stuff?
- 30. The kcachegrind call graph
- 31. The kcachegrind call graph Do we need any TCA in Eid? No
- 32. Change 3 – Remove unneeded code: (Resources/Private/Eid/rates.php): Before: tslib_eidtools::connectDB(); tslib_eidtools::initTCA(); $TSFE = t3lib_div::makeInstance('tslib_fe', $GLOBALS['TYPO3_CONF_VARS'], ...); After: tslib_eidtools::connectDB(); $TSFE = t3lib_div::makeInstance('tslib_fe', $GLOBALS['TYPO3_CONF_VARS'], ...);
- 33. Total Time Cost 2877900 ( ~ -45%)
- 34. Summary ● From 12769352 => 2877900 (-77%) with three changes ● Additional Ideas: ● Reduce created fluid objects by implementing static fluid view helpers (examples in fluid core) ● Cache reverse conversion rate (1/rate) ● Use APC Cache Backend for TYPO3 and Extbase caches
