 Description: 
 
i5-3230m Dual Core Four thread,%CPU maximum value can reach 400%.
 
PHP has built a web Server from 5.4.0 to facilitate phper testing and development, and Linux is a single-threaded application, so the CPU usage of the PHP process is always under 100%.
And Tomcat is a multithreaded Java application, CPU consumption is very strong, high peak even 330%!
 
PHP test after the memory only up 0.5MB, and Java process memory up 1 time times, memory fluctuation is very large, up to 180 MB, PHP memory consumption of more than 9 times times!
 
PHP CLI Server has more processing requests per second than Java Tomcat1500, while memory and CPU usage is much smaller than Java Tomcat, is Java too low-energy, or PHP very fast?
