search for: 300mbps

...To inicial test I've create script, using qemu commands, to build two VM's and test the nic speed. Each VM has one nic, using virtio, into it own bridge. In this bridge we associate one 10gbe physical nic. They can communicate each other. When we try do a copy, through SCP, the speed is 300mbps. And if we open another copy this speed been the half. What we are using: S.O: CentOS 7 Kernel 3.10.0-123.el7.x86_64 qemu-kvm.x86_64 10:1.5.3-60.el7 libvirt-daemon.x86_64 1.1.1-29.el7 Hardware: Dell PowerEdge R720 16GB RAM 2TB SAS Two Broadcom Corporation NetXtreme II BCM57810 10...

...the traffic through L1 and L2. Every interface is gigabit. (Realtek NICs) I''m using IMQ on L1 and L2, to separate the traffic into 2 zones, international and local, with HTB for shaping. The system works fine for some time, but when the traffic hits 200Mbps, and ocassionally bursts to 250-300Mbps, L1 and L2 behave strangely (packet loss > 30%, increased latency +20ms), sometimes they even hang, leaving me with the only solution: rebooting them. I''ve checked the CPU usage, it stays around 80% during the highest traffic. I''ve examined the logs, and here is what i'...

Hello listmates, I would like to build a 12-15 TB RAID 5 data server to run under ContOS. Any recommendations as far as hardware, configuration, etc? Thanks. Boris.

...e between these two files and other files I think that the problem is with number of rules. Is there any limits for sfq and can I increase them? router hardware configuration: dual p4 xeon 2.4Ghz ; 1GB/ram ; two nics e1000/64bit running kernel is 2.4.27 traffic that pass through router is about 300mbps 40-50kpkt/sec Any help, suggestions or comments on that will be appreciated.

...me <remote_ip> doveadm dsync-server -uuser at host.com -U It happened around 2am. I restarted the new server dovecot process and it started to copy back up again, and then happened about four hours later. I have about 10,000 accounts, and it chugs through the list to replicate pretty well (~300Mbps), so I know it's working. Just not sure why it's failing after it's working so great. Running 2.2.13 on both on FreeBSD. Both show this: # doveadm replicator status Queued 'sync' requests 0 Queued 'high' requests 0 Queued 'low' requests 0 Queued 'failed...

I tried compression levels 0,1,9,10 and 1,9 did slow down transmission by 20-40% (360Mbps to 250-300Mbps), 0,10 were about the same. I do not think compression could greatly benefit me, as most transmitted data will already be compressed. If tinc is not fast enough, I was thinking about using a second VPN like wireguard point-to-point between each server where possible (even an SSH tunnel would get n...

Hello listmates, We are working on setting up two private networks linked by a public network which is fast (1 Gbit/s) but potentially insecure. Since the hosts on our two networks need to talk to each other, and do so securely, we have decided to use OpenVPN to connect them, making one gateway a server and the other a client. The connectivity part was easy to establish and worked like a charm.

...s a hostap for my home. I am thinking to use an Alfa (http://www.alfa.com.tw) usb wireless adapter or TP-Link. BUt there is not much information in Alfa's or TP-Link's web sites about which of them can run as a HostAP. If I can find any adapter that supports ac with a throughput of 150 Mbps/300Mbps, it would be great. Any recommendation? Maybe AWUS036ACH and TP-TLW722N can supports this functionality, but I am not sure ... Thanks. -- Greetings, C. L. Martinez

...In test case, ICMP packets going through boxes have normally about 5ms latency. When running nft (regardless command for listing set with few items or with several thousand items) latencies go up to 30-100ms. This is observed when router throughput is from 600Mbps to 2Gbps. When throughput is about 300Mbps, latecies go up too, but to 8-12ms. Routers are using multiple NICs queues with affinity to CPU cores, maximum load when tests were performed was about 10-20%. Userspace processes (including nft) are affined to other cores than NICs queues. Older boxes with iptables but similar ruleset have no su...
