tcp throughput test

The fastest speed is that non-WCF named pipelines on the local machine have 113 MB/S The fastest speed for local network machines to transfer files is to use TCP binding of WCF, with a speed of 70 ~ 120 MB/S Test speed comparison: Local Data Transfer Mutual transmission of LAN machines HTTP binding for WCF 104 ~ 116 Mbit/s buffer mode (0.21 Mbit/s for 25 Mbit/s ~ 0

After the installation of network hardware and network protocol, we generally have to do the TCP/IP protocol testing, then how to test is a more comprehensive test? We believe that comprehensive testing should include two aspects of local area network and Internet, so it should be tested in two aspects of LAN and Internet, the following is the steps we use to

connections is much higher, the program consumes less CPU resources. The average CPU occupancy rate is about 7%. The memory footprint of the server is about 2.6G, and the actual operating system's memory is full.SummarizeDue to the limitations of memory in these tests can not run to 100w connection a little pity (but after the idle time to add memory and then will be bored to brush again) ...; As a result, it is possible to further illustrate a very important

In some scenarios, a large number of message broadcast forwarding exists. net socket TCP performance in this regard, so a relatively extreme information broadcast forwarding strength test. the test scenario is to use 400 pieces of connection information to broadcast each other as a test case. When one connection sends

number of connections is much higher, the program consumes less CPU resources. The average CPU occupancy rate is about 7%. the memory footprint of the server is around 2.6G, because the memory of the actual operating system that does not control the socket level is full. SummarizeDue to memory limitations in these tests can not run to 100w connection a little pity. A very important question has been further explained from the results The ability to measur

UNIX Domain Socket IPCThe socket API was originally designed for network communication, but later developed an IPC mechanism on the socket's framework, UNIX Domain socket. Although the network socket can also be used for interprocess communication with the same host (via loopback address 127.0.0.1), the UNIX Domain socket is more efficient for IPC: it does not need to go through the network protocol stack, does not need to package unpacking, calculate checksum, maintain serial number and answer,

Httping is an HTTP request client that simulates ping output. The Fastopen request is supported from 1.5 and the current version is 2.3.4. I compiled the Nginx 1.5.13,yum on Fedora 20 (kernel version 3.13) and installed httping 2.3.3 version. Open two terminals, one running tcpdump, and then another running httping as follows: Httping-f-G http://www.google.com.hk/url-c 1This is when you see the output of the previous terminal: [chenlin.rao@com21-100 tfo]$ sudo tcpdump-i p5p1-vvnxxs 0

How to analyze the HTTP or TCP packets captured by the packet capture tool during the test Http://www.docin.com/p-101479451.htmlC/S communication interface testing often causes many problems due to incorrect request structure or packet sending errors. Usually, you need to use the packet capture tool to capture the sent packets, after further analysis, we can easily see the existing errors. Based on my own s
