HTB performance improvement Hi all ! i''m looking at the performance of the HTB algorithm/implementation because i would like more packets/sec !! this is the scenario of the performance test: i''m using an embedded system with: SPEED CPU: 399,999 MHz RAM: 128 MByte FLASH: 16 MByte EEPROM: 8Kbyte PROCESSOR MPC8272 a lan to lan 10/100 and in particular we are sending

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

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

hello. i have following setup: a machine (winChip 200mhz cpu, 32mb ram, linux 2.4.28) acting like a bridge with 2 interfaces (eth0 - to our ISP, eth1 - to our network) machine does not have any IP there is a 802.1q vlan eth0.2 eth0.2 and eth1 are bridged in br0 i have one 4mbit link which i share with my friend, i have 3mbit and he has 1mbit all our IP addresses are public and we have the

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 have configured my server with cbq and gred. The problem is that the cbq doesnt drop packets. The cbq is configured at a rate of 500Kbit "qdisc cbq 4: rate 500000bit (bounded,isolated) prio no-transmit Sent 100103048 bytes 73933 pkts (dropped 0, overlimits 0) borrowed 0 overactions 0 avgidle 24000 undertime 0 " The traffic that being generated is more than 5Mbit with the

Hi, I am trying to implement a simple scaled-down version of the AF traffic class type. As such I basically want to remark non-conforming AF11 packets to AF13. Here is m script that I have been using on the ingress router of my network: ---------------------------------------- Link=''dev eth1'' Rate1=''rate 800Kbit'' Rate2=''rate 2500Kbit''

Hi, I am trying to do the simplest configuration of traffic shaping. So I did: shorewall.conf TC_ENABLED=Simple tcinterfaces eth0.2 External 500kbit tcdevices eth0.2 500kbit 200kbit And I am testing the speed on that interface - whether I did it ok or not, and my speed is still 4mbit/512kbit. So the question is - How to reduce the speed on interface connected

Hi all, Supposedly my router is itself streaming traffic to clients. Is it possible for it to mark its packets before going through dsmark?? I have gone through the examples in iproute2/examples, i noticed that there''s always an ingress and egress of which these are 2 different dev. Is it possible for before ingress and egress be the same dev?? I tried the script below but

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

Hello list I have a problem with classifying traffic from two providers, and about 600 users. I have the following situation: P1-\ | linux | --eth0-| box |-eth1 P2-/ | | P1 and P2 are coming from VLANs. I have 4 type traffic which I want to classify. The traffic is divided as follows: P1 - 100mbit from realm 0x70000 10mbit from realm ! 0x70000

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, 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
