¿Por qué el performance importa?
Meetups
● Dejar un mundo más verde.○ Menos recursos necesarios.○ Menos energía gastada.
● $$$$○ Otra forma de ver el punto anterior.
● Happy users ⟹ More users (SEO)○ 40% of users abandon a website that takes more than 3 seconds to load.
● Fama.○ http://www.techempower.com/benchmarks/○ http://benchmarksgame.alioth.debian.org/u64q/php.html
¿Como se consigue performance?
Meetups
● Cliente: Optimizar assets (guetzli), JS, Chrome DevTools...● Red: HTTP/2, comprimir tráfico (TLS 1.3 0-RTT)...● Servidor: cache, optimizar servidor, optimizar aplicación.● Base de datos: saltar ORM/ODM, desnormalizar esquema, cache...
¿Como se consigue performance en PHP?
Meetups
Usa PHP7 (Con OPcache)
¿Como se consigue performance en PHP?
Meetups
Usa PHP7 (Con OPcache y sin Xdebug)
Sobre performance
Meetups
Antes de optimizar, mide mucho y bien. (blackfire.io)
¿Que es blackfire.io?
Meetups
● Profiler para PHP● Mejora la UX de XHProf (y de var_dump([microtime(), memory_get_usage()]);)● De los creadores de Symfony ● Saas● Instalar servicio linux (docker) y zend_extension● Vale para peticiones HTTP y para CLI● Blackfire puede ser usado en cualquier fase del ciclo de video de tu aplicación: durante el
desarrollo, test, pre-produccion and produccion, para medir, test, debug y optimizar su performance.

consumes 90% less memory!● Optimizing league/commonmark with Blackfire.io: Two simple changes led to a whopping 52.5%
performance boost!● Pomm: A two hours run with Blackfire.io: "35% performance improvement is a major enhancement in
such a test case."● ownCloud: Recent Performance Optimizations: "Enthusiasm around the tool is becoming very visible,

Consejos
Meetups
● Primero usa PHP7 (y OPCache).● Antes de optimizar, mide mucho y bien. (blackfire.io)● Conoce tus herramientas (time) (@igrigorik). ● PHP no vale para todo. (@julienPauli)● La optimización prematura es la raíz de todos los males. (Donald Knuth)● You can optimise for execution speed. You can optimise for space.
But the most precious thing you should optimise for is understandability
