Hi,
How can I control the size of the block requests the sendfile() syscall
performs
against the disk?
I'm using sendfile (on a 2.6.18 kernel) to copy 1M file chunks into a
socket. The
socket send buffer size is 2MB, and I verify that its empty before
making the call.
Indeed, 1M chunk is being sent, but from iostat, I can tell that the
average request
size is around 128KB. Are there any kernel configuration variables that
could change that?
Help will be appreciated.
