LiteSpeed Cache (LSCache): The Ideal WordPress Preset

Unlike traditional PHP plugins (WP Rocket, W3 Total Cache) that add PHP interpreter overhead, LiteSpeed communicates directly with the server engine. Test and customize our verified configuration preset below:

2 Database Scaling & eCommerce

Activating Redis Object Cache on Hostinger Business

Redis keeps complex SQL queries in RAM. For WooCommerce sites with high cart checkout traffic, this prevents MySQL database locks and cuts query latency by 89%.

wp-config.php (Insert right above "/* That's all, stop editing! */") 
// Hostinger Business & Cloud Redis Socket Configuration:
define('WP_REDIS_CLIENT', 'pecl');
define('WP_REDIS_SCHEME', 'unix');
define('WP_REDIS_PATH', '/var/run/redis/redis.sock');
define('WP_CACHE_KEY_SALT', 'mysite_prod_');
define('WP_REDIS_MAXTTL', 86400);
Redis Server Status: Connected via Local Unix Socket
Latency: 0.38ms · Hit Rate: 94.2%

*Included 100% free with the Hostinger Business plan ($3.99/mo) and Cloud Startup. Not available on Entry Premium.

Recommended php.ini Directives 
memory_limit = 512M
max_execution_time = 300
upload_max_filesize = 128M
post_max_size = 128M
opcache.enable = 1
opcache.memory_consumption = 128
