我按照所有的指示在这里：
https://github.com/laravel/valet/issues/315
我注意到了更好的性能，特别是在更新了Valet的PM池配置之后。（现在一些执行开始完成，因为所需的时间不到60秒）。
但是对于更长的执行，仍然在60秒之后显示错误。
实际上我的确认文件是这样的：

• • 代客-fpm.配置**

; FPM pool configuration for Valet

[valet]
user = xxx
group = staff
listen = /Users/xxx/.config/valet/valet.sock
listen.owner = xxx
listen.group = staff
listen.mode = 0777

;; When uncommented, the following values will take precedence over settings declared elsewhere
;php_admin_value[memory_limit] = 512M
;php_admin_value[upload_max_filesize] = 128M
;php_admin_value[post_max_size] = 128M

;php_admin_value[error_log] = /Users/xxx/.config/valet/Log/php-fpm.log
;php_admin_flag[log_errors] = on

;; Note: increasing these values will increase the demand on your CPU and RAM resources
pm = dynamic
;pm.max_children = 5
;pm.start_servers = 2
;pm.min_spare_servers = 1
;pm.max_spare_servers = 3

pm.max_children = 200
pm.start_servers = 20
pm.min_spare_servers = 10
pm.max_spare_servers = 20
pm.process_idle_timeout = 10s
pm.max_requests = 500

我还需要修改什么？先谢了
