tcp throughput test

Preface You can use the test TCP Program (TTCP) to measure the TCP throughput through the IP path. Use it to start the receiver at one end of the path, and then start the transmitter on the other side. The transmitting end sends the specified number of the TCP information pa

When I finish writing a TCP Service, do I really want to immediately test the performance of this service? What kind of request processing can it handle? What is its performance. I believe the following small tool can help you with your small business. It is a small tool based on beetle. You only need to set the parameters to perform a simple throughput performan

If you are writing a socket TCP Service and want to know whether the current write service has good performance in data sending and receiving, you can use this tool to test it. This tool will establish 1000 connections to the server, and send information to the service according to the interval you set and the packet size. The service only needs to send the data back. The delay is just a reference, becau

In Internet search engines, the most commonly used keyword for network testing is "network speed testing". From the log of an Heng website, statistics on the access volume of this keyword can account for 30% of the keywords of network testing technology. This shows how much people are concerned about the speed test of the network. This article discusses the methods and applications for testing network and inter-network

, confirm to the end received, in order to continue to slide the window to send new data. You can see that the window size has a significant impact on throughput, while the ACK response is closely related to system latency. It is necessary to note that if the sending side of the window over the assembly caused the receiver to close the window, processing not to the contrary, if the window settings are small, the result is not enough bandwidth, so care

Maximum TCP Throughput = Valid data for a RTT transfer/RTT line Efficiency = maximum throughput/channel bandwidth Channel efficiency can be understood as: the ratio of the bandwidth that is actually utilized to be provided. So you can see a problem. In a TCP connection, the channel bandwidth is 1gb/s, the sending w

Valve Game company Open source Gamenetworkingsockets[1], both support reliable data transmission, but also support unreliable data transmission, its data transmission is based on UDP, the implementation of TCP-friendly congestion control mechanism to ensure the fairness of bandwidth occupancy. [2] Its rate-control formula is based on a famous paper. Now, record its bandwidth calculation program here for a rainy time: Const Int64 k_nmillion = 1000000;

perform the Iperf function test as a client at this point.1. Testing TCP ThroughputTo determine the maximum throughput of a network card, you can run the Iperf command on any client, and Iperf will attempt to send data requests to the server as quickly as possible from the client and output the amount of data sent and the average bandwidth of the NIC. Figure 1 i

It is very important to improve the throughput performance of multi-core servers. Because servers are different from desktops and workstations, the channel for dealing with the outside world is the network. No matter what complicated computing operations the processor performs, the results must be returned to the request object through the NIC. In a sense, the NIC is the "throat" component of the server for external contact and communication. To some

between them to guide the data packet transmission direction. 1. Chariot introduction: Chariot is currently the only application-layer IP network and network device testing software recognized in the world. It provides end-to-end, multi-operating systems, multi-protocol testing, and multi-application simulation testing. Its application scope includes wired, wireless, local area, wide area networks and network devices; Network Fault Locating, user complaint analysis, system evaluation, netwo

PS: The following is the main concept and calculation formula of performance test, note: A System Swallowing metric elements: A system's swallowing metric (pressure-bearing capability) is closely associated with the request's CPU consumption, external interface, IO, and so on. The higher the CPU consumption of a single reqeust, the slower the external system interface and IO impact, the lower the system throughput
