Pick a PHP process mode.
LiteSpeed offers three suEXEC process modes so shared hosts can balance memory, speed and flexibility.
➜ ~
Which Mode Is For You?
| Mode | How it works | Recommended for |
|---|---|---|
| Worker | Standard LSAPI; creates processes when needed. | Hosts with limited resources who need custom php.ini files. |
| Daemon | Forks every process from a constantly running daemon. | Shared hosts that don't need custom php.ini files. |
| ProcessGroup | Each account gets its own parent process to fork from. | Hosts with spare RAM who want the strongest opcode caching. |
