[Qemu-devel] [PATCH 0/3] nbd: use TCP_NODELAY

2013-04-15 Thread Stefan Hajnoczi
The nbd block driver should use TCP_NODELAY. Nick Thomas measured a 40 millisecond latency added by the Naggle algorithm. This series turns on TCP_NODELAY. This requires that we use TCP_CORK to efficiently send NBD requests that contain a payload after the header. Finally, fix a bug where we f
