Test the file transfer speed comparison between HTTP and TCP bindings of WCF and non-WCF named Pipelines

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 ~ 0.23 seconds) 40 ~ 45 Mb/s stream mode (0.5 Mbit/s for 25 Mbit/s ~ 0.6 seconds)	50 ~ 60 Mb/s buffer Mode 7 ~ 10 Mb/s stream mode
TCP binding of WCF	290 ~ 370 Mbit/s buffer mode (0.07 s for 25 MB) (The name pipeline of WCF only needs 0.07 S) 60 ~ 70 MB/S stream mode	70 ~ 120 Mbit/s buffer mode (0.20 Mbit/s for 25 Mbit/s ~ 0.37 seconds) 2 ~ 3 Mb/s stream mode
Non-WCF named Pipeline	113 MB/S	10 Mb/s

The cache size used in the buffer mode is greater than the file size (that is, all files are put into the memory first). This is a way to exchange resources for speed. In actual use, it cannot consume too many resources.

The buffer layer is used for file write operations.

I hope you can communicate with others.

 

During the test, the buffer size of the read method is 15000. It is found that the buffer speed is too slow. To a certain extent, the data cannot be received and will be terminated in advance.

Test TCP and find that each read has a rule:

First obtain 255,

Second 4089,

Third 6,

Fourth and later 4089

Is this the legendary three-way handshake?

Test HTTP and find that each read operation is 4096
