je viens de modifier le fichier /etc/php/8.4/fpm/php-fpm.conf

# cat /etc/php/8.4/fpm/php-fpm.conf | grep -v "^$" 
;;;;;;;;;;;;;;;;;;;;;
; FPM Configuration ;
;;;;;;;;;;;;;;;;;;;;;
; All relative paths in this configuration file are relative to PHP's install
; prefix (/usr). This prefix can be dynamically changed by using the
; '-p' argument from the command line.
;;;;;;;;;;;;;;;;;;
; Global Options ;
;;;;;;;;;;;;;;;;;;
[global]
; Pid file
; Note: the default prefix is /var
; Default Value: none
; Warning: if you change the value here, you need to modify systemd
; service PIDFile= setting to match the value here.
pid = /run/php/php8.4-fpm.pid
; Error log file
; If it's set to "syslog", log is sent to syslogd instead of being written
; into a local file.
; Note: the default prefix is /var
; Default Value: log/php-fpm.log
error_log = /var/log/php8.4-fpm.log
; syslog_facility is used to specify what type of program is logging the
; message. This lets syslogd specify that messages from different facilities
; will be handled differently.
; See syslog(3) for possible values (ex daemon equiv LOG_DAEMON)
; Default Value: daemon
;syslog.facility = daemon
; syslog_ident is prepended to every message. If you have multiple FPM
; instances running on the same server, you can change the default value
; which must suit common needs.
; Default Value: php-fpm
;syslog.ident = php-fpm
; Log level
; Possible Values: alert, error, warning, notice, debug
; Default Value: notice
;log_level = notice
; Log limit on number of characters in the single line (log entry). If the
; line is over the limit, it is wrapped on multiple lines. The limit is for
; all logged characters including message prefix and suffix if present. However
; the new line character does not count into it as it is present only when
; logging to a file descriptor. It means the new line character is not present
; when logging to syslog.
; Default Value: 1024
;log_limit = 4096
; Log buffering specifies if the log line is buffered which means that the
; line is written in a single write operation. If the value is false, then the
; data is written directly into the file descriptor. It is an experimental
; option that can potentially improve logging performance and memory usage
; for some heavy logging scenarios. This option is ignored if logging to syslog
; as it has to be always buffered.
; Default value: yes
;log_buffering = no
; If this number of child processes exit with SIGSEGV or SIGBUS within the time
; interval set by emergency_restart_interval then FPM will restart. A value
; of '0' means 'Off'.
; Default Value: 0
;emergency_restart_threshold = 0
; Interval of time used by emergency_restart_interval to determine when
; a graceful restart will be initiated.  This can be useful to work around
; accidental corruptions in an accelerator's shared memory.
; Available Units: s(econds), m(inutes), h(ours), or d(ays)
; Default Unit: seconds
; Default Value: 0
;emergency_restart_interval = 0
; Time limit for child processes to wait for a reaction on signals from master.
; Available units: s(econds), m(inutes), h(ours), or d(ays)
; Default Unit: seconds
; Default Value: 0
;process_control_timeout = 0
; The maximum number of processes FPM will fork. This has been designed to control
; the global number of processes when using dynamic PM within a lot of pools.
; Use it with caution.
; Note: A value of 0 indicates no limit
; Default Value: 0
process.max = 128
; Specify the nice(2) priority to apply to the master process (only if set)
; The value can vary from -19 (highest priority) to 20 (lowest priority)
; Note: - It will only work if the FPM master process is launched as root
;       - The pool process will inherit the master process priority
;         unless specified otherwise
; Default Value: no set
; process.priority = -19
; Send FPM to background. Set to 'no' to keep FPM in foreground for debugging.
; Default Value: yes
;daemonize = yes
; Set open file descriptor rlimit for the master process.
; Default Value: system defined value
rlimit_files = 2048
; Set max core size rlimit for the master process.
; Possible Values: 'unlimited' or an integer greater or equal to 0
; Default Value: system defined value
;rlimit_core = 0
; Specify the event mechanism FPM will use. The following is available:
; - select     (any POSIX os)
; - poll       (any POSIX os)
; - epoll      (linux >= 2.5.44)
; - kqueue     (FreeBSD >= 4.1, OpenBSD >= 2.9, NetBSD >= 2.0)
; - port       (Solaris >= 10)
; Default Value: not set (auto detection)
;events.mechanism = epoll
; When FPM is built with systemd integration, specify the interval,
; in seconds, between health report notification to systemd.
; Set to 0 to disable.
; Available Units: s(econds), m(inutes), h(ours)
; Default Unit: seconds
; Default value: 10
;systemd_interval = 10
;;;;;;;;;;;;;;;;;;;;
; Pool Definitions ;
;;;;;;;;;;;;;;;;;;;;
; Multiple pools of child processes may be started with different listening
; ports and different management options.  The name of the pool will be
; used in logs and stats. There is no limitation on the number of pools which
; FPM can handle. Your system will tell you anyway :)
; Include one or more files. If glob(3) exists, it is used to include a bunch of
; files from a glob(3) pattern. This directive can be used everywhere in the
; file.
; Relative path can also be used. They will be prefixed by:
;  - the global prefix if it's been set (-p argument)
;  - /usr otherwise

-------- Recommendations ---------------------------------------------------------------------------
General recommendations:
    MySQL was started within the last 24 hours: recommendations may be inaccurate
    We will suggest raising the 'join_buffer_size' until JOINs not using indexes are found.
             See https://dev.mysql.com/doc/refman/8.0/en/server-system-variables.html#sysvar_join_buffer_size
    Temporary table size is already large: reduce result set size
    Reduce your SELECT DISTINCT queries without LIMIT clauses
    MyISAM engine is deprecated, consider migrating to InnoDB
    Before changing innodb_log_file_size and/or innodb_log_files_in_group read this: https://bit.ly/2TcGgtU
Variables to adjust:
    join_buffer_size (> 256.0K, or always use indexes with JOINs)
    key_buffer_size (~ 24M)
    innodb_log_buffer_size (> 24M)
