Hi All,
i have a linux redhat 8.0 as my ftp server. when i
try retrieve file from ftp server from a winxp laptop i can get ~
30Mbps.
when i retrieve file from a Debian client with
kernel 2.6.9 i only can get ~ 7Mbps.
when i try retrieve file from a FC3 pc i have ~
85Mbps.
All machine are connected to a same switch and all
linux machine have optimized kernel turning as shown below,
#net.core.rmem_max = 67108864
echo 67108864 > /proc/sys/net/core/rmem_max #net.core.wmem_max = 67108864
echo 67108864 > /proc/sys/net/core/wmem_max #net.core.rmem_default = 65536
echo 65536 > /proc/sys/net/core/rmem_default #net.core.wmem_default = 65536
echo 65536 > /proc/sys/net/core/wmem_default #net.ipv4.tcp_rmem = 4096 87380 67108864
echo "4096 87380 67108864" > /proc/sys/net/ipv4/tcp_rmem #net.ipv4.tcp_wmem = 4096 65536 67108864
echo "4096 65536 67108864" > /proc/sys/net/ipv4/tcp_wmem #net.ipv4.tcp_mem = 8388608 8388608
67108864
echo "8388608 8388608 67108864" > /proc/sys/net/ipv4/tcp_mem I wish to know why so much different ?
thanks,
