h2. server.network-backend option
+server.network-backend+
The basic network interface for all platforms at the syscalls read() and write(). Every modern OS provides its own syscall to help network servers transfer files as fast as possible
* linux-sendfile - is recommended for small files.
* writev - is recommended for sending many large files
* gthread-aio - available from lighttpd 1.5. As of r1605, this is compiled in by default (ie, lighttpd will not compile without glib2 >= 2.4.0 installed). gthread is provided by glib2. The package in redhat is named "glib2" and in debian and ubuntu "libglib2.0-dev"
* posix-aio - uses librt (or libc on FreeBSD)
* linux-aio-sendfile - available when libaio is installed on the system. On Centos 4/RHEL4, you can install libaio by doing
yum -y install libaio-devel
Enabled when lighttpd is configured with <code>--with-linux-aio</code>
Note: (Note: linux-aio is disabled in lighttpd-1.5-svn but can be re-enabled by modifying several files. ( files http://trac.lighttpd.net/trac/changeset/2002 )
