PHP 8 alpha 1 was released on June 25th, and php 8 alpha 2 was released on July 9th. Generally, alpha 2 is a slightly usable version, so I evaluated it over the weekend. What is the php8 JIT?
Let’s take a look at the results first:
When JIT is not turned on
php -d opcache.jit_buffer_size=0 Zend/bench.php simple 0.025simplecall 0.012simpleucall 0.012simpleudcall 0.012mandel 0.135mandel2 0.211ackermann(7) 0.082ary(50000) 0.012ary2(50000) 0.010ary3(2000) 0.186fibo(30) 0.283hash1(50000) 0.039hash2(500) 0.041heapsort(20000) 0.089matrix(20) 0.110nestedloop(12) 0.096sieve(30) 0.045strcat(200000) 0.019------------------------ Total 1.419
When JIT is turned on:
php -d -d opcache.jit_buffer_size=64M -d opcache.jit=1205 Zend/bench.php simple 0.001simplecall 0.000simpleucall 0.000simpleudcall 0.000mandel 0.005mandel2 0.006ackermann(7) 0.010ary(50000) 0.005ary2(50000) 0.004ary3(2000) 0.011fibo(30) 0.027hash1(50000) 0.027hash2(500) 0.018heapsort(20000) 0.011matrix(20) 0.011nestedloop(12) 0.006sieve(30) 0.004strcat(200000) 0.009------------------------ Total 0.155
There are also cases where Opcache is not turned on Next:
php Zend/bench.php simple 0.051simplecall 0.017simpleucall 0.083simpleudcall 0.089mandel 0.506mandel2 0.409ackermann(7) 0.095ary(50000) 0.012ary2(50000) 0.010ary3(2000) 0.187fibo(30) 0.367hash1(50000) 0.040hash2(500) 0.041heapsort(20000) 0.097matrix(20) 0.122nestedloop(12) 0.093sieve(30) 0.063strcat(200000) 0.018------------------------ Total 2.299
Do not enable Opcache: 2.299s When Opcache is enabled but JIT is not enabled: 1.419s When Opcache is turned on and JIT is turned on: 0.155s
With JIT turned on, it is close to 9.15 times that without JIT turned on. After multiple tests, this value is stable between 8 times and 10 times.
In order to be close to our business, we test under the mpf framework
aliyun centos 6.9
php7.test.com php-fpm one process php8.test.com php-fpm one process
Mpf two interfaces
/v1/hello/wzh/index1
public function index1() { $this->output('123'); }
/v1/hello/wzh/index2
public function index2() { $a = 0; for ($i = 0; $i < 1000000; $i++) $a++; $this->output($a); }
Let’s do a stress test
php7 When there is less calculation

php7 When there is too much calculation

13times, and the more calculations, the more obvious the optimization. When there are many calculations, php8JIT is25.7times the performance of php7.
