Specifically on my local 100Mbits network the samba read speed on the server (athlon 1700) is < 1Mbit/sec, while the write speed is much much worse. If I ftp to that machine I have read speed of minimum 7Mbits/sec. I am puzzled why the samba has so much worse performance. Is anyone that using samba on his freebsd machine without any performance loss? Or what typical read/write speeds do usually achieve on your samba +freebsd machine? Also if you have extra tips and tricks about samba and freebsd that can boost the performance, they would be much appreciated. About tunning parameters and so on....This machine will be the main server of a laboratory of the university, and its not acceptable to have a low speed. Thanks very much in advance!! P.s. I searched the net and I saw the people suggested changing the net.inet.tcp.delayed_ack value, or measuring with tcpdump the MSS window size and trying to put a formula on it to calculate the parameter SO_RCVBUF Of the samba and various other tricks....Do they have a point? P.s.2 I am also mounting with SUIDDIR the filesystems. Does this make a performance loss?
