这是重写为我domain.conf中的php文件的问题
location / {
location ~* ^.+\.(jpeg|jpg|png|gif|bmp|ico|svg|css|js)$ {

}

fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
if (!-f $document_root$fastcgi_script_name) {
return 404;

问题是，当许多用户连接到服务器时，nginx worker进程的cpu负载增加到100％
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND

20109 nginx 20 0 71260 5200 952 S 17.5 0.1 0:22.48 nginx: worker process
php脚本使用readfile（）函数并根据几个参数（geo，用户代理等）返回数据
有人可以解决nginx cpu高负载的问题吗？
更新-php代码：
<?php
$time = 10e6;
$uid = 'uid';
$config_aa = 'aa/config_aa.js';
$config_bb = 'bb/config_bb.js';
$config_cc = 'cc/config_cc.js';
$config_other = 'other/config_other.json';
$COUNTRY_CODE = isset($_SERVER["HTTP_CF_IPCOUNTRY"]) ? $_SERVER["HTTP_CF_IPCOUNTRY"] : $COUNTRY_CODE = 'UNDEFINED';
if ($COUNTRY_CODE == 'AA' || $COUNTRY_CODE == 'UNDEFINED') {
if (round(microtime(true) * 1000) - $_GET[$uid] > $time ) {
header('Content-type: application/javascript');
readfile($config_aa);
readfile($config_bb);
exit;
}
else {
header('Content-type: application/javascript');
readfile($config_cc);
exit;
}
}
if ($COUNTRY_CODE == 'BB') {
if (round(microtime(true) * 1000) - $_GET[$uid] > $time ) {
header('Content-type: application/javascript');
readfile($config_aa);
readfile($config_bb);
