Freenas domU network performance issue
Hi guys, I''m running a freenas domU (FreeBSD 8.3 based, ZFS v28, 2 vcpus mapped to the same HT capable core) to serve storage for all purpose including other domUs running on the same host. I did some study to understand how well it works and the result is kind of confusing. In summary, the network performance between domains on the same host is worse than expected. And NFS service to

poor throughput with tinc
Hi, I am testing tinc for a very large scale deployment. I am using tinc-1.1 for testing. test results below are for tinc in switch mode. all other settings are default. test is performed in LAN env. 2 different hosts. I am getting only 24.6 Mbits/sec when tinc is used. without tinc on the same hosts/link I get 95 to 100 Mbits/sec using iperf.

IFB0 throughput 3-4% lower than expected
I have two boxes for the purpose of testing traffic control and my knowledge thereof (which is at the inkling stage). The boxes are connected by 100Mbit ethernet cards via a switch. For egress traffic via eth0 I achieve a throughput that is close to the specified CEILing, particularly for values above 1mbit. Ingress traffic does not seem so well behaved. Above about 1mbit rates achieved are about 3-4% less than the CEILing. Has this been your e...

TC/CBQ shaping problems
...everyone, I''m a newbie experimenting with CBQ shaping and am facing a few problems. Can any of you please help?

Traffic from 10.0.0.103 to 10.0.0.102 port 2000 should always receive at least 60Mbit/s regardless of presence of other traffic. 2. In the absence of traffic to 10.0.0.102 port 2000, all other t...

Where is my bottleneck?
I'm running rsync via ssh on two machines connected with 100 Mbit/s Ethernet cards (at high speed) via a Linksys switch. It's all right here in a single closet. I'm sending large files (initial transfer, nothing preexists on the destination machine) and seeing transfer rates in the 2 Mbit/s range. The CPUs on both machines are more than 90% idle, and I...

I've also used 1.0.4 beforehand and experienced the same problem with it. 1) I initialize the bits, encoder, and decoder as normal (default settings seemed appropriate): speex_bits_init(&mBits); mEncode = speex_encoder_init(&speex_nb_mode); mDecode = speex_decoder_init(&speex_nb_mode); 2) I record my audio at mono 8000Hz, 16bits per sample. 3) I encode frame-sized (320 bytes) fragments.

VLANs with Xen - work with 1 Gbit, doesn''t with 100 Mbit cards?
...etwork-bridge" "$@" vifnum=1 netdev=eth0.100 bridge=xenbr100 "$dir/network-bridge" "$@" vifnum=2 netdev=eth0.200 bridge=xenbr200 If the server has a 1 Gbit network card (e1000, tg3 module), VLANs work flawlessly. If, however, I replace the card, and use a 100 Mbit one (Intel/e100 or Realtek/8139too module), and don''t change the scripts, VLANs are not working. Why is it so? What is so fundamental in Xen networking that VLANs behaviour change so much whether one uses a 1 Gbit, or 100 Mbit network cards? There is one difference between 1 Gbit and 1...

Another GPLPV pre-release 0.9.11-pre7
I''ve just uploaded 0.9.11-pre7. save/restore should be working for 32 bits on both SMP and UP, and maybe for 64 bits although it''s not tested. If someone could test migration it would be much appreciated. The installer seems to not install the drivers under 64 bit environment... but they can then be installed manually. Not sure why at this point.

Copy 100gb+ file over LAN?
...es (in the 4GB to 20GB range) and it seems to work well only transferring the changes over the internet. My usual method has been to map the Windows 2003 drive on the local linux server and then use rsync. When trying this with this system, the transfer speed is super slow from the beginning, at 6 mbit per second on a 10/100 mbit network. If I try the copy using smbclient and get, I actually get 60 mbit p/sec for the first 30gb, then it seems to slow to 6 mbit. A regular cp does basically the same thing as it starts out fast and then slows all of a sudden. This obviously will not be very practica...
