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. Over Tinc: iperf -c 192.168.9.9 -b 100m -l 32k -w

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

Hi, below are some test results from implementing a prio qdisc ''that is also below''. The qdisc is attacted to a vlan interface for my external network. Both tests were run at the same time. The links are policed at 6.0M ''by our provider''. 192.168.70.1 --> 192.168.30.1 My question is: If using a prio qdisc should''nt the iperf run with a tos of b8 have

connection will remain a TCP connection unless it is broken and restarted. Usually if I stop the client and wait for about 30 seconds to reconnect, there is a much greater chance that the MTU probes work fine, and in about 30 seconds MTU is fixed to 1416. Every time when the MTU probing fails, I see latency between 700 - 1000 ms with 32 byte pings over a LAN. Every time when the MTU probing does

I have a Dell server with four bonded, gigabit interfaces. Bonding mode is 802.3ad, xmit_hash_policy=layer3+4. When testing this setup with iperf, I never get more than a total of about 3Gbps throughput. Is there anything to tweak to get better throughput? Or am I running into other limits (e.g. was reading about tcp retransmit limits for mode 0). The iperf test was run with iperf -s on the

Hi, I am seeing a performance degradation while using libvirt to start my vm (kvm). vm is fedora 12 and host is also fedora 12, both with 2.6.32.10-90.fc12.i686. Here are the statistics from iperf : >From VM: [ 3] 0.0-30.0 sec 199 MBytes 55.7 Mbits/sec >From host : [ 3] 0.0-30.0 sec 331 MBytes 92.6 Mbits/sec libvirt command as seen from ps output : /usr/bin/qemu-kvm -S -M

Hello list, I have two differents installation Xen Hypervisor on two identical physical server, on the same switch : The problem is on my new server (Xen 4.0.1 with pvops kernel 2.6.32.24), I have bad performance on bandwidth I have test with a files copy and "iperf". Result iperf average: Transfert Bandwidth XEN-A -> Windows

Hi all, I set up a samba server into Debian 3.2.0-4-amd64. This runs as guest OS into VirtualBox machine over OS X host OS. Connection seems pretty good: $ iperf -s ------------------------------------------------------------ Server listening on TCP port 5001 TCP window size: 85.3 KByte (default) ------------------------------------------------------------ [ 4] local 192.168.0.21 port 5001

Hi, I want to do some analysis of NTOP data. Currently I have installed NTOP on Centos 5.1 and I am able to see some network data being graphed. But there is no documentation given whether NTOP is showing Network Throughput in MBytes or MBits for ex I am getting Throughput Min: 163.7k , Max: 3.0 M and Last 859.4k and there are some options like anomalia, upper,lower and trend (30min). Under

Hi, I'm having some weird problem with the setup of the QoS on a bridged network. As the docs states, outbound/inbound average speed should be expressed in KBps (KBytes per second) but in order to get a maximum speed of 10Mbps (megabits per second) surprising enough I have to use 2560 on the guest (not 1280 as expected). Using 1280 units I get a speed og 5Mbps. I'm aware of peak and

I did some testing using samba-3.0.0 as a server and two identical clients one Running W2K and other running Win XP pro. If I write a big file using the W2K client, I'm getting about 25 Mbytes/sec but if I run the same testing using the Win XP Pro, this client only is able to get 12.5 Mbytes/sec. There is a problem between XP and samba?

Hi, I have a problem with a large data set wrapped in a reference class. I do that to access the data by reference from within various functions in a script. # The class definition: setRefClass("data", fields = list(h5_df = "list", training_data = "array",

Hi, In a setup where OpenVSwitch is used with GRE tunels on top of an interface provided by tinc, I'm experiencing significant performance degradation problems (from 100Mb/s down to 1Mb/s in the worst case) and I'm not sure how to fix this. The manifestation of the problem is, from the user point of view, iperf reports ~100Mb/s and rsync reports ~1Mb/s: $ iperf -c 91.224.149.132

Hi, I'm using R to collect data for a number of exchanges through a socket connection and constantly running into memory problems even though task I believe is not that memory consuming. I guess there is a miscommunication between R and WinXP about freeing up memory. So this is the code: for (x in 1:length(exchanges.to.get)) { tickers<-sqlQuery(channel,paste("SELECT Symbol

Hi, I have some network problems with my DomUs (etch) on a debian etch running xen 3.0.3. The domain0 is a DL360 G5 with tg3 network card If i download something from outside my dom0 box to a domU, i get this network rate: ~865kbits ... and it must be ~ 10Mbits, i think. Doing some tests with iperf i get this: [ 4] local outside_server port 5001 connected with _domU_ port 54889 [ 4]

Hello everybody. We had a Samba 3.024 on a old computer. It's disks begun to fail and we decided to replace the computer with a new one. I installed a Lenny and a Samba 3.2.5. I've two problems of slowness : * If I open a large pdf ( around 5 Mbytes ) on any computer and if I want to print it ( directly from the computer to the printer, we do not use Samba as a print server )
