Typically, on both my local development environment, and on the servers I deploy most Magento sites on, I am running on the Apache web server. We recently decided to try installing Nginx on a server to see how well it ran Magento. The results were stunning.
I will probably have more posts on this eventually, so forgive the lack of information in this post. I just wanted to get the word out there at least that I am extremely impressed with Nginx. It is blazing fast. Just today I ran an import of just over 26,000 customer records, and it completed it (importing 5 records at a time) in under 30 minutes. That’s fast!
So you may want to check it out if you are interested in a much, much faster server environment for Magento (and for anything else for that matter).
