Ros Fetch number Threading analysis (4): Without assembly: socket option SO_SNDBUF,SO_RCVBUF effects on bandwidth and CPU

Yesterday, with Ros, Iperf, Nettest tested the bandwidth and CPU occupancy of the CMM02NODE06-->CMM02NODE01, sending a packet length of 2KB, the test results are:Bandwidth send-side CPU utilization at the receiving end CPU usageROS 4.42gb/s, 80% 100%Iperf 4.66gb/s, 100% 70%Nettest 4.38gb/s, 100% 71%found that both Iperf and nettest are send-side CPU reached 100%, and the receiving end only accounted for the 70%;ros is the receiving end CPU reached 100

See how dynamic routing protocols save network bandwidth

It is very important to know about dynamic routing protocols. Here we mainly introduce how dynamic routing protocols save network bandwidth and manage network bandwidth. In a network without other routers, it is meaningless to route the Broadcast Communication outbound from the network interface. This is very inefficient for your network bandwidth and vro resourc

Use a router to limit the bandwidth traffic of a LAN

When using a router to limit the bandwidth traffic of a LAN, sometimes the bandwidth is not very high at work, but the speed of normal internet access is slow due to the excessive use of bandwidth by others, normal operations cannot be carried out, so managing the bandwidth traffic of hosts in the LAN is essential. Www

Calculate the bandwidth of a Cisco switch Backboard

Calculate the bandwidth of the backboard of a Cisco switch. It is the maximum amount of data that can be transferred between the vswitch interface processor, interface card, and data bus. The higher the bandwidth of the backboard of A vswitch, the stronger the ability to process data, but the design cost will also rise. Www.2cto.com but how can we check whether the band

Relationship between PV traffic and bandwidth

. IP address is a concept that reflects virtual address objects in the network. An independent user is a concept that reflects the actual user. Each independent user is more accurate to a visitor than each IP address. Using Independent users as statistics, you can more accurately understand how many visitors actually come to the corresponding page per unit time. One independent IP Address can generate multiple PVS, so the number of PVS is greater than or equal to the number of IP addresses. P

Testing for Azure Bandwidth

See before customers often meet some customers ask us your azure bandwidth is how much, each answer this question we can only vaguely tell the customer a approximate value, this will leave the customer to think we are very unprofessional impression, in fact, standing in the customer's perspective, we can understand, Even such a question you can not accurately answer, how can I believe that you can help me to carry out, so I and my colleague time measu

How to Use the Router Protocol to save network bandwidth

Using the vro protocol is very important for the use of routing, and it can also get a lot of convenience, So I studied how to use the vro protocol to save network bandwidth, I would like to share it with you here and hope it will be useful to you. Managing network bandwidth is becoming increasingly important. In a network without other routers, it is meaningless to route the Broadcast Communication outboun

Typical Fault solution for eliminating ADSL bandwidth

Error 678 during dialing Fault performance: Windows XP SP2 operating system, ADSL virtual dialing user. The error 678 is displayed when you click "Broadband connection. According to

Learn how to extend the bandwidth access server

Broadband Access Servers are still commonly used. So I have studied the extended functions of broadband access servers. I will share them with you here, hoping they will be useful to you. The above section briefly introduces the system structure and access functions of the broadband access server. In fact, the broadband access server function is far from the same. In terms of specific network implementation, the bandwidth access server has changed the

NetLimiter: allows network bandwidth to be used in the cutting edge

Chat, email sending, download, online video ...... Many of my friends perform these operations at the same time. How can I allocate a limited bandwidth? In this case, we only need to use NetLimiter to allocate bandwidth reasonably. First install the installation program at http://www.netlimiter.com/download/nl_v130.exe. When the software is installed for the first time, a network configuration window will

The relationship between bandwidth and download rate

Before today, it is always considered that the 2M bandwidth download speed should be 2m/s, but this is not true. The following is an example of the 1M bandwidth to explain the relationship between the bandwidth and download speed that you just understood.Bandwidth is the "highest data rate" that can be passed from one point in a network to another.1M==1MB? The an
