Hi Alan,
- Have you tried to use the TCP_CORK feature? According to the
sendpage man page you can use it to fine tune the transmission;
Yes, I tried that, but it didn't change the read sizes.
- Have you tried to increase the sending and receiving output thru'
the SO_SNDBUF and SO_RCVBUF setsockopt parameters?
Yes, I use 2MB send and receive buffer sizes, which is 4x times the size
of the read operations I intend to do, but it does not change the file
system read sizes either, which are still ~128K.
