Using sendfile() system call you win by not copying data through FS - IO cache - user space - JVM streams - network sockets, system 'just' copies data from FS/IO cache to network socket. Much, much more faster.Still, since you can guarantee that everything is in memory if you customize your webapp, and apache httpd simply relies on the file system cache which has it's own behaviour, not designed for your webapp, a single filesystem "miss" will cost more time than you'll ever win by maybe saving some system calls.
You don't want to keep all static content in memory, for JVM to send it? ;-)
The less resource expensive your solution is, the more apps/servers/etc you can run on single machine. That means less money you have to spend, or more bussiness you can run.I also assume that a modern server will never reach its cpu limit before reaching the bandwith limit by simply writing out data.
