PHP Configuration

OPcache Settings

[opcache]
opcache.enable=1
opcache.memory_consumption=256
opcache.interned_strings_buffer=64
opcache.max_accelerated_files=30000
opcache.validate_timestamps=0
opcache.save_comments=1
opcache.jit_buffer_size=256M
opcache.jit=1255

validate_timestamps=0 disables file modification checks. Config/route/view caches must be rebuilt on deploy.

Memory Settings

memory_limit=512M
post_max_size=100M
upload_max_filesize=100M
max_execution_time=60
max_input_time=60

PHP-FPM Pool

[www]
user = www-data
group = www-data
listen = 127.0.0.1:9000

pm = dynamic
pm.max_children = 50
pm.start_servers = 5
pm.min_spare_servers = 5
pm.max_spare_servers = 35
pm.max_requests = 500

Process Manager Modes

Mode	Behavior
static	Fixed number of children
dynamic	Scale between min/max
ondemand	Spawn on request

dynamic balances memory usage and response time.

Recommended Tuning

For production, adjust based on available memory:

max_children = (Total RAM - OS overhead) / Average PHP process size

Typical PHP process: 30-50MB. On a 4GB server:

max_children = (4000 - 500) / 40 = ~87

Start conservative and monitor memory usage.
