Hi, I noticed something odd. It is definately reproducable, in fact: it happens EACH attempt. Tested with kernel 2.6.36.
What happens: - 1 system running both nbd client and server - nbd connection is set up, not mounted or so, only the connection between the server and client - then th server proces is shot down - after that nbd-client -d /dev/nbd0 is invoked Then, again if nbd-client + server is running and iozone3 is tested, the performance drops around 30% or more! It then stays that way until rebooted. Folkert van Heusden -- MultiTail รจ uno flexible tool per seguire di logfiles e effettuazione di commissioni.
