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

Hi, what is Samba speed limit? I usually get maximum throughoutput about 3-4 MBytes/s reading from Samba, 2-3 MB/s writing to Samba server. (IDE discs, but 256 MB memory, Athlon 900 MHz, one 500 MB file, 100 Mbit network). What are your results? Does anybody knows about some performance tunings? I have adjusted only this: socket options = TCP_NODELAY SO_RCVBUF=16384 SO_SNDBUF=16384 write cache

about 30mbits/s (3750kBytes/s) from a Windows NT Workstation to the Samba server, and, as strange as it may be, 25mbits/s (3175kBytes/s) from the Samba server to the NT Workstation. Using FTP, I get the same both ways (30mbits/s)... I don't know why my from Samba to Windows speed is slower than the other direction, but the speed is not bad for a Pentium 100, so i'm not complaining. What

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

2.4.18 kernel) using 3 x 60GB WD 7200 IDE drives on a 7500-4 controller I could get peak I/O of 452 MBytes/sec, and a sustainable I/O rate of over 100 MBytes/sec. That is not exactly a 'dunno' performance situation. These tests were done using dbench and RAID5. Let's get that right: 100 MBytes/sec == 800 Mbits/sec, which is just a tad over 100 Mbits/sec (the bottleneck if you use

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

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 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).

Hi, I am trying to set up my linux box on an NT Domain, I can connect to the NT servers if I specity my NT Domain password on the command line i.e. smbclient \\SERVER\NETLOGON -uid%password but if I just do a smbclient \\SERVER\NETLOGON then enter my password when requested it gets rejected. Also I have shares on my linux samba box but when I try to connect to the linux box using my NT
