| |
Hi,
Can someone give me a pointer to a FAQ on how to tune a 2.4 machine to achieve high throughput (approx i/f speed 100Mbits/sec) on a link with the following characteristics:
Latency Throughput
9-10ms 3.8 MByte/s 3-4ms 7-8MByte/s
I have implemented:
echo "4096 87380 4194304" > /proc/sys/net/ipv4/tcp_rmem echo "4096 65536 4194304" > /proc/sys/net/ipv4/tcp_wmem
from http://www-didc.lbl.gov/tcp-wan.html
this lifted the performance from ~1MByte/s to the 3.8 above.
When the receiving machine is freebsd I get 10.05 MBytes/s which is interesting - but when sending from BSD I get the same rate.
cheers Mark
