I wish there was more input as to why Apache 2.4 isn't suitable. It's been 3 years since its event driven model was released and it is a perfectly acceptable web server even for static content.

Apache 2.4 isn't event driven. The Apache's Even MPM only handles keep-alive connections asynchronously, while the whole request processing is still synchronous. It solves only one problem of Apache, but it still doesn't make it as scalable as nginx.

  Hi, I'm one of the main authors (along with others, it is a community driven project) of the Event MPM for Apache. On Benchmarks and timelines: I agree that 2.2+ was not widely available for many years due to the update cycle of linux distributions, but at the time nginx wasn't in the distros... so it become a thing where people would yum install apache2, get a 2-5 year old version, and they would benchmark that against an ngnix from their latest dev download. The original work for the Event MPM started around 2004: http://mail-archives.apache.org/mod_mbox/httpd-dev/200411.mbox/%3C41868F73.9010602@force-elite.com%3E http://mail-archives.apache.org/mod_mbox/httpd-dev/200411.mb... The version in 2.2 was mostly focused on Keep-Alive requests. Apache 2.2.0 was first kicked out on December 1, 2005. To go beyond Keep-Alive requests, is a set of features/patches called "Async Write Completion". Much of this work was done in 2006-2007 by Graham Leggett: https://mail-archives.apache.org/mod_mbox/httpd-dev/201510.mbox/%3C28641C04-8936-4004-BA40-C889C8B7846A@sharp.fm%3E https://mail-archives.apache.org/mod_mbox/httpd-dev/201510.m... Timing wise, most of that work did not find its way into a stable release until 2.4, which came out February 17, 2012. This is the date the article references.

    Thanks for your work on Apache. Do you recommend any published benchmarks of modern Apache vs. modern Nginx?

      There are a few benchmarks of Apache 2.4: 1. http://www.eschrade.com/page/performance-of-apache-2-4-with-the-event-mpm-compared-to-nginx/ http://www.eschrade.com/page/performance-of-apache-2-4-with-... 2. http://mondotech.blogspot.ru/2012/02/apache-24-vs-nginx-benchmark-showdown.html http://mondotech.blogspot.ru/2012/02/apache-24-vs-nginx-benc... 3. http://blog.zhuzhaoyuan.com/2012/02/apache-24-faster-than-nginx/ http://blog.zhuzhaoyuan.com/2012/02/apache-24-faster-than-ng...

        Those look to be a few years old. :-)
