I know, but imagine how much memory you can save and use for file system cache if you are not running apache. Which can make fat more greater impact on your performance. You can't just say that nginx is the same as apache just because it's blocking on file I/O.
So still, it depends on the type of load you are having. And if you are not serving 100 megabytes of data to 500 clients but a lot more you are most likely to get better results with asynchronous server even with blocking file I/O.
