slow linux network file transfer, file copy - centos v4.8, v5.3, v5.5
Hello,
I am seeing very slow linux-to-linux or windows-to-linux file transfer rates. It's about 7kb/sec vs windows-to-windows tranfer rates of approximately 49kb/sec.
I have a large number of Linux servers and several windows servers on a layer 2 gigabit network. No servers have firewall or SElinux. OS is mostly Centos v4.8 and v5.3 with some v5.5. I have checked each server and they show eth0 as gigabit full duplex, no or very low lost packets. I'm also running Capsa and it doesnt show a lot of collisions. I've tested dns, reverse dns, etc.
I've also pulled two of the Linux servers and placed it on a small 5-port linksys gigabit switch with my windows laptop and a windows server with the same results as above. Is there something basic I am missing? Does Linux have some sort of encryption going on that I can turn off?
Authentication is by Files then NIS but this happens even when I login root.
