Modern LAMP Stack Configuration

The LAMP stack powers over 30% of the web. Modern versions offer significant performance gains.

PHP 8.3 JIT Compilation

PHP 8 introduced the Just-In-Time compiler. Enable it in `php.ini`:

opcache.enable=1
opcache.jit_buffer_size=100M
opcache.jit=tracing

Apache HTTP/2

HTTP/2 multiplexing reduces latency.

sudo a2enmod http2
sudo a2enmod ssl

Update your virtual host config:

<VirtualHost *:443>
    Protocols h2 http/1.1
    ServerName mysite.com
    # ... SSL configuration
</VirtualHost>
