Test on slow table data deletion: recently, I was bored with my watch and found that data deletion is far from faster than query. As a result, I made an experiment. The experiment content is as follows, and the level is limited. I hope it will serve as an example to help you understand this problem as much as possible! I hope that our predecessors can clearly and relentlessly correct the unreasonable operations and incorrect ideas of our younger sibli

Now the person who wrote the book is a bit of a sense of responsibility, recently read a few books, where the code is wrong.Recently obsessed with Python games, bought "Getting started with Python game programming" [US] Jonathan S. Harbour a book to see.In the fourth chapter: Bomb catcher game, the program code to test typing speed is seriously wrong.Change the program screen randomly display a letter, the

Speedtest.net provides the command line tool speedtest-cli. in Linux, we can use speedtest-cli to test the broadband speed. speedtest-cli is a lightweight Linux command line tool compiled by Python based on Speedtest.net. architecture to measure the network's upstream/downstream speed running environment: python2.4-3.4 github: https://github.com/siv Speedtest.net

As mentioned above, we can only optimize the code that affects the speed. The Benchmark_Timer class and Benchmark_Iterate class in the benchmark package of PEAR can be used to conveniently test the speed of script execution. (For installation and configuration of PEAR, see relevant information ). First, use the Benchmark_Iterate class to

Ubuntu11.10 is coming soon. On the eve of its arrival, foreign Netizens found that its (OneiricOcelot version) boot speed was unsatisfactory. Whether it's PC or laptop, Intel CPU or AMDCPU, or traditional hard disks or SSD, Ubuntu11.10 is not as fast as previous versions. On Multiple test platforms, the boot speed of Ubuntu11.10 is better than that of Ubuntu11.04

1. DD Command Brief:if= input file, of= output file, ibs= bytes read at a time, obs= write bytes at a time, bs= set the number of bytes written at one time, skip= skipped BS number, count= copy block number2. Using/dev/null and/dev/zero　　1. Treat/dev/null as a "black hole", which is equivalent to a write-only file, and all content written to it will be lost forever2./dev/zero is a pseudo-file, but it actually produces a continuous stream of NULL3.
