Network performance under proxmox

[cnnie]

Hello,
we setup a proxmox server and created a RedHat kvm guest.
We are using the virtio driver for storage and network devices.
Our networkperformance is really poor. We used netio for the performance test.
On the physical proxmox server (debian) we strat "netio -s" (the server is waiting for client requests).
We start then "netio -t ip_address_of_proxmox" with the following results:
NETIO - Network Throughput Benchmark, Version 1.26

TCP connection established.
Packet size 1k bytes: 28493 KByte/s Tx, 18563 KByte/s Rx.
Packet size 2k bytes: 17531 KByte/s Tx, 25760 KByte/s Rx.
Packet size 4k bytes: 22431 KByte/s Tx, 38178 KByte/s Rx.
Packet size 8k bytes: 23378 KByte/s Tx, 57981 KByte/s Rx.
Packet size 16k bytes: 30291 KByte/s Tx, 38465 KByte/s Rx.
Packet size 32k bytes: 24924 KByte/s Tx, 19766 KByte/s Rx.
Done.

Regardless how nice and simple proxmox is, we can't work with such performance.

Is that a normal value?
If not, what went wrong?

Thx,
Clemens Niemeyer

pls use other benchmark tools, netio is not usable due to license restrictions of the author (no commercial use allowed).

so if you provide an easy howto others can also post their results. do not forget to post the guest settings (version, architecture, vm settings - post the /etc/qemu-server/VMID.conf).

I had the same problem with virtio-driver. The e1000e-driver is much faster. So you shoud use this.
