The Apache Software Foundation officially released the Apache 2.4 today as the first major update to this leading open-source web-server in more than a half-decade. Apache 2.4 is slated to deliver superior performance to its 2.2 predecessor and better compete with the growingly-popular NGINX web-server.

Besides much faster performance, among the many enhancements to the Apache 2.4 HTTP Server is better a-synchronous support in its core, run-time loadable MPMs, reduced memory usage compared to Apache 2.2.x, several new modules, enhancements to existing modules, and much more.

Apache HTTP Server 2.4 provides a number of improvements and enhancements over the 2.2 version.
