ID5fe16888d33af7aca0d613d888c161af68c755c3

Added by Laurent Vivier over 13 years ago

Improve qemu-nbd performance by 4400 %

This patch allows to reduce the boot time from an NBD server from 225 seconds to
5 seconds (time between the "boot cd:0" and the kernel init) for the
following command lines:

./qemu-nbd -t ../ISO/debian-500-powerpc-netinst.iso
and
./ppc-softmmu/qemu-system-ppc -cdrom nbd:localhost:1024

This patch combines the reply header and payload send operation.
