After setting it, I am getting steady 2.9MB/s on write via 100MBit network. The problem has been solved! Futhermore, I examined sysctl -a output and set "sysctl -w net.inet.tcp.delayed_ack=0". After that, Samba rocked! (850KB/s on write via 10MBit/s network). Is there any good source of information about sysctls? manpages are very brief and do not cover all sysctls. --------------------------------------------------------------------------- Dr. Sergey Ayukov Sternberg Astronomical Institute http://www.ayukov.com Moscow, Russia http://crydee.sai.msu.ru/index-asv.html To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
