压力测试
压测脚本中创建了一个 PyDict ,分别读写 PHP 代码和 Python 代码执行 1000 万次。
PHP 版本:PHP 8.2.3 (cli) (built: Mar 17 2023 15:06:57) (NTS)Python 版本:Python 3.11.5- 操作系统:
Ubuntu 20.04 GCC 版本:gcc version 9.4.0 (Ubuntu 9.4.0-1ubuntu1~20.04.2)
请注意设需要构造一个
1000HashTable,需要至少2G以上内存空间才可以运行此测试
PHP
<?php $dict = new PyDict(); const COUNT = 10000000; $n = COUNT; $s = microtime(true); while ($n--) { $dict['key-' . $n] = $n * 3; } echo 'dict set: ' . round(microtime(true) - $s, 6) . ' seconds' . PHP_EOL; $c = 0; $n = COUNT; $s = microtime(true); while ($n--) { $c += $dict['key-' . $n]; } echo 'dict get: ' . round(microtime(true) - $s, 6) . ' seconds' . PHP_EOL; Python
import time my_dict = {} COUNT = 10000000 n = COUNT start_time = time.time() for i in range(n): my_dict["key-" + str(i)] = i * 3 elapsed_time = time.time() - start_time print(f"dict set: {elapsed_time:.6f} seconds") n = COUNT total = 0 start_time_get = time.time() for i in range(n): total += my_dict["key-" + str(i)] elapsed_time_get = time.time() - start_time_get print(f"dict get: {elapsed_time_get:.6f} seconds") PHP 数组
<?php ini_set('memory_limit', '2G'); $dict = []; const COUNT = 10000000; $n = COUNT; $s = microtime(true); while ($n--) { $dict['key-' . $n] = $n * 3; } echo 'array set: ' . round(microtime(true) - $s, 6) . ' seconds' . PHP_EOL; $c = 0; $n = COUNT; $s = microtime(true); while ($n--) { $c += $dict['key-' . $n]; } echo 'array get: ' . round(microtime(true) - $s, 6) . ' seconds' . PHP_EOL; 结果对比
(base) htf@swoole-12:~/workspace/python-php/docs/benchmark$ php dict.php dict set: 4.663758 seconds dict get: 3.980076 seconds (base) htf@swoole-12:~/workspace/python-php/docs/benchmark$ php array.php array set: 1.578963 seconds array get: 0.831129 seconds (base) htf@swoole-12:~/workspace/python-php/docs/benchmark$ python dict.py dict set: 5.321664 seconds dict get: 4.969081 seconds (base) htf@swoole-12:~/workspace/python-php/docs/benchmark$ 以 Python 测试为基准:
| 脚本名称 | Set | Get |
|---|---|---|
| dict.php | 114% | 125% |
| array.php | 337% | 599% |
phpy以PHP代码写入PyDict的性能比原生Python高14%,读取性能高25%PHP写入PHP Array的性能比Python 写入 Dict高237%,读取高出了近500%
其他
phpy 这个项目已经进化到可以调用任何 python 内置常量、函数、模块,包括 print 、compile 、eval 、exec 等等,也就是说你完全可以用 php 的语法来写 python ,比如
https://docs.python.org/zh-cn/3/library/ast.html#module-ast 示例代码:print(ast.dump(ast.parse('x = 1'), indent=4)) php 写法: $py = PyCore::import('builtins'); $ast = PyCore::import('ast'); $py->print($ast->dump($ast->parse('x = 1'), indent: 4)); 以上只是写着玩,phpy 的初衷是用 python 来弥补 php 生态上的不足,现在你可以用 php 来跑大模型了
