Hello, i hope somebody has an idea for my problem and may point me to the right direction. Alle servers run kernel 3.18.14.
My problem is that i can't archieve more than 20Mbit/s using a single TCP stream and i've no further ideas how to solve it. reduced Network Map Server A | Linux GW Server | Brocade Router - Server B | Internet | Server C The Linux GW Server does nothing more than being an ip forwarding GW. (no iptables / packet filtering). I've done the following Tests while the Linux GW has a traffic of around 500-600Mbit/s: Download file from Server A to C: 10-20Mbit/s Download file from Server A to B: 100Mbit/s Download file from Server B to C: 100Mbit/s 4 parallel downloads from Server A to C: 80-100Mbit/s Same test with no other traffic on the Linux GW: Download file from Server A to C: 100Mbit/s Download file from Server A to B: 100Mbit/s Download file from Server B to C: 100Mbit/s 4 parallel downloads from Server A to C: 100Mbit/s Same test with net.ipv4.tcp_congestion_control=bic on Server A: Download file from Server A to C: 70Mbit/s Download file from Server A to B: 100Mbit/s Download file from Server B to C: 100Mbit/s 4 parallel downloads from Server A to C: 80-100Mbit/s ehtootl -S shows no errors for eth0 and eth1 on the linux gw. I've no further ideas. Thanks a lot.
