I have been using SubSonic3.0 for a while and have been looking for opportunities to test the paging speed of various queries and compare the query efficiency of the plug-in. So I wrote the test program yesterday, prepare data tables with records of 1 K, 1 W, 10 W, 50 W, and W, and perform a detailed test in the mornin
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

I. File Read speed
In Linux, reading files is implemented by calling sys_read (FD, Buf, count) by the system. Therefore, to increase the speed, it is the simplest way to call the sys_read encapsulation, for example, read () or fread () is used directly (). Below are some tests in Linux.

Run the dd command in CentOS to test the read/write speed of the USB flash disk.
1. Brief description of the dd command:
If = input file, of = output file, ibs = number of bytes read at a time, obs = number of bytes written at a time, bs = set the number of bytes read and write at a time, skip = number of bs skipped, count = number of copies

As mentioned earlier, it is possible to optimize only if we find code that affects speed. The Benchmark_timer class and Benchmark_iterate class in the Pear benchmark package can be used to easily test the speed of script execution. (For pear installation and configuration, please check the relevant information yourself).
First, use the Benchmark_iterate class to
