The box is a p2-300/128M, one 10mbit NIC. During a testload of a client doing a streaming write (storing a single large file) the server experiences userspace loads (as expressed by top) of ~45% cpu by the smbd process. The write rate sustains at ~430-450 kbytes/s. samba-2.2.3a linux-2.5.64 glibc-2.3.1 read-raw=yes/no (no diff) write-raw=yes/no (no diff) kernel oplocks=yes blocking locks=yes fake oplocks=no level2 oplocks=yes socket options=(|TCP_NODELAY) (|SO_SNDBUF=8192) (|SO_RCVBUF=8192) (no diff) regards, Samium Gromoff
