search for: 40mbps

Hello I have a 3 node experiment as detailed below to estimate the bridged networking performance in para-virtualized Xen 3.0 on Emulab (https://www.emulab.net/) Here is how the 3-node topology looks (This topology is specified by means of an NS-2 file) topology: _______________________________ | | Node0:eth0 ------|Node1:eth0

Hi, I have a server and ten clients in a Gigabit network. The server has 125mbps network bandwidth. I want that the server has 40Mbps bandwidth reserved for client 1 (IP 192.168.5.141), and the rest bandwidth is for all other clients. My script looks like this (I use IFB for incoming traffic): #!/bin/bash export TC="/sbin/tc" $TC qdisc add dev ifb0 root handle 1: htb default 30 r2q 100 $TC class add dev ifb0 paren...

Hi all, I dont know if this problem is related to shorewall, but as here we have a lot of firewall experts ... :) We are using a Leaf box (1GHz 256MB RAM) for a network with normal traffic of about 6Mbps but peaks of up to 40Mbps. The chipset of the ethernets is a Realtek. We are experiencing some high latency high CPU usage issues (the CPU is at 90%) and we discovered the process ksoftirqd_CPU0 could consume up to 50% of that. We are using a 2.4.26 kernel and have NOT compiled any optimization regarding network besid...

Hi all: I use Charito to test xen default network(pcnet), and ne2000 performance, to my surpise, the average throughput of the default is 40Mbps, but the average throughput of ne2000 is 18Mbps, how can this happen? Besides, I see from xen wiki that : "The default network card which QEMU uses in Vt-x is AMD PCnet-PCI II Ethernet Controller. (*file tools/ioemu/hw/pcnet.c*). The reason to prefer this nic emulation to the other alterna...

...setup a linux fileserver, and used the SMB protocol to share the data. Right now I'm just trying to work all the kinks out, so both the fileserver and the client run linux, but in the future I will have Windows clients. Transfering files between the same two computers is very fast with NFS (~20-40MBps... gigabit ethernet, switched... no hubs) but with Samba its very slow at ~2MBps, and the latency is a bitch sometimes. For example, if I watch an AVI off of my fileserver, and try to fast forward, it takes tens of seconds for it to update, compared to virtually instantanious if the AVI is stored l...

Hi All, I started a 501c3 (not-for-profit) organization back in February 2011 to deal with information archival. A long vision here, I wont bore you with the details (if you really want to know, e-mail me privately) but the gist is I need to build an infrastructure to accommodate about 2PB of data that is database stuff, stored video, crawl data, static data sets, etc. Right now in my testing of

I can't seem to get the read and write performance better than approximately 40MB/s on an ext2 file system. IMO, this is horrible performance for a 6-drive, hardware RAID 5 array. Please have a look at what I'm doing and let me know if anybody has any suggestions on how to improve the performance...

Hi all, First, let me say I''ve been most impressed with how quickly and professionally people on this list ask and answer questions. Next, let me say that with which I need help is properly configuring strict PQ, and gathering certain stats. Specifically: - I need to create a priority queue with four queues (let''s say they are of high, medium, normal, and low priority) - I

Hi, I want to configure CentOS on powerful server with gigabit adapters as transparent bridge and deploy it in front of server farm. Can you tell how to optimize the OS for hight packet processing? What configurations I need to do to achieve very hight speeds and thousands of packets? -------------- next part -------------- An HTML attachment was scrubbed... URL:

Greetings, Can anyone relate experience(s) installing CentOS on Compaq rack mount servers units please? Easy no problem, easy some issues, or ghastly do not do it under any circumstances... ;) Basically, I'm looking at some used/refurb dual PIII units and will run RAID on Compaq built in SCSI or is it easy to pop in some 3ware SATA in them? Let me know in terms of CentOS 3 and/or 4 please.

...$7c6e21d0$5964a8c0@SalimSi> Content-Type: text/plain; charset="us-ascii" I tested on wireless link. It could give a maximum of 45Mbps. And I sent 30Mbps of both low prio and high prio traffic. Total of 60Mbps. My test was done with UDP, using tcpdump. When I increased the bandwidth to 40Mbps each, the high priority class got lesser bandwidth. (maybe the effect of the known issue that large amount of low prio traffic can starve high prio traffic) > -----Original Message----- > From: lartc-bounces@mailman.ds9a.nl [mailto:lartc-bounces@mailman.ds9a.nl] > On Behalf Of Christian B...

The GEM and PRIME related callbacks in struct drm_driver are deprecated in favor of GEM object functions in struct drm_gem_object_funcs. This patchset converts the remaining drivers to object functions and removes most of the obsolete interfaces. Patches #1 to #16 and #18 to #19 convert DRM drivers to GEM object functions, one by one. Each patch moves existing callbacks from struct drm_driver to
