On FreeBSD 7.2 with the patch
http://sysoev.ru/html/freebsd/patch.readahead.txt

sendfile    on;
tcp_nopush  on;
aio         sendfile;
read_ahead  512k;

On Linux:

sendfile    on;
read_ahead  1;

On Linux nginx calls
posix_fadvise(0, 0, 0, POSIX_FADV_SEQUENTIAL);
and the read_ahead value is ignored.

perl_modules  /path1/to/modules;
perl_modules  /path2/to/modules;
perl_modules  /path3/to/modules;

limit_req_log_level  [info|notice|warn|error];
limit_conn_log_level  [info|notice|warn|error];

The directives set log level for messages about limiting requests and
connections.
