connection, request, and bandwidth.

HTTP/2 performance. HTTP2 server push
ESI (Edge Side Include) Cache
Punch holes for private/changeable data on
public pages using ESI. Together with
LSCache, ESI lets you serve the entire
mixed-content page from cache.
Brotli compression (superior to gzip) available
for both static and dynamic content.
TFO (TCP Fast OPEN)
Speeds up TCP connections.
Cutting Edge Technologies
Better than cPnginx
No need for messy NGINX-Apache hybrid
setups. Removes one layer of proxy, which
means faster serving of dynamic content.
No more Varnish needed
LSCache is faster and uses less
CPU/memory compared to Varnish. No
extra layer for HTTPS termination
No need to migrate to NGINX
No need to deal with NGINX rewrites. Stop
harassing your sys-admins.
No more wasting time tuning your Apache
LiteSpeed has an event-driven architecture like
NGINX. Apache is a multi-process, multi-
threaded server, which cannot come close to the
performance of an event-driven server, no
matter how you tune it.
No additional complex setup required
