FPM
یا همون FastCGI Process Manager برای مدیریت پردازش های fast cgi هست
These features include:
- Adaptive process spawning (NEW!)
- Basic statistics (ala Apache's mod_status) (NEW!)
- Advanced process management with graceful stop/start
- Ability to start workers with different uid/gid/chroot/environment and different php.ini (replaces safe_mode)
- Stdout & stderr logging
- Emergency restart in case of accidental opcode cache destruction
- Accelerated upload support
- Support for a "slowlog"
- Enhancements to FastCGI, such as fastcgi_finish_request() - a special function to finish request & flush all data while continuing to do something time-consuming (video converting, stats processing, etc.)
