Hi. We might need more context ; e.g. pool configuration, what kind of web application could it be, was cpu usage significantly lower with previous php releases .. etc ...

php.ini:
[opcache]
opcache.enable=1
opcache.enable_cli=1
opcache.interned_strings_buffer=128
opcache.max_accelerated_files=20000
opcache.save_comments=1
opcache.jit=1235
opcache.revalidate_freq=0
opcache.validate_timestamps=1
opcache.max_accelerated_files=10000
opcache.memory_consumption=192
opcache.max_wasted_percentage=10
opcache.interned_strings_buffer=16
opcache.fast_shutdown=1
opcache.jit_buffer_size=500000000

and php-fpm pool:

pm.status_path = /fpm-status
slowlog = log/$pool.log.slow
security.limit_extensions = .php .php3 .php4 .php5 .php7 .php8
php_admin_value[upload_max_filesize] = 5M
php_admin_value[error_reporting] = E_ALL & ~E_NOTICE & ~E_WARNING & ~E_STRICT & ~E_DEPRECATED
php_admin_value[mysqli.allow_local_infile] = 1

pm = dynamic
pm.max_children = 16
pm.start_servers = 2
pm.min_spare_servers = 2
pm.max_spare_servers = 5
pm.max_requests = 1000
pm.process_idle_timeout = 60s
rlimit_files = 131072
rlimit_core = unlimited
catch_workers_output = yes

Thanks.

was cpu usage significantly lower with previous php releases

The reason I ask, often this kind of report comes from major migrations e.g. from 8.2 to 8.4 when behavior differences could be witnessed.

i'm experiencing issues since 8.3 that was the reason to try 8.4 and it performs like that since that moment. Only way to lower cpu usage is just restart service via service php_fpm restart.
