I think when they did benchmarks for Lighttpd, AIO was the fastest
solution. Is there any benefit to caching in VM? Files requested a lot
or small files?

Is there an easy way to check blocksize? I use XFS typically.

Also, since this is DIRECTIO, this is not really a good idea over NFS
right? I think I saw in the Linux kernel that DIO support in NFS was
experimental etc. but I'm not sure I'll get much benefit out of it...
