SSD and NVMe improve I/O operations
Solid state storage reduces latency for file reads, CMS work, logs, file cache and database operations. NVMe is especially useful with many parallel input/output operations, but disk speed alone will not fix slow code, heavy plugins or unindexed SQL queries.
LSAPI lowers PHP handling overhead
LSAPI is an optimized way for the web server to communicate with applications. In practice it can shorten the request path to PHP, use memory efficiently and work with cache mechanisms. In cPanel/CloudLinux environments the exact handler available depends on account and server configuration, so we treat LSAPI as one optimization layer next to PHP-FPM.
Cache and interpreter matter as much as storage
OPcache keeps compiled PHP code in memory, LSCache can serve a page without running the full application path, and Redis or Memcached can reduce database queries. Fast hosting is a combination of I/O, PHP, cache, databases, LVE isolation and application quality.
When should you ask support?
If a website has high TTFB, a slow WordPress panel, heavy SQL queries, a plugin update problem or weak PageSpeed results, Hostilla.pl support can help check PHP, cache, databases, LVE limits and application components.
