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
6. But I expect a lot of
visitors. Can you handle
them?
Yes, we can!
12. Install XDebug & KCachegrind
● Install xdebug
(eg. apt-get install php5-xdebug)
● Install kcachegrind
(eg. apt-get install kcachegrind)
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.
22. 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;
}
Change 1 (SoapConversionRateProvider)
23. 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;
}
Change 1 (SoapConversionRateProvider)
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?
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'], ...);
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
