Have you noticed that IE will automatically load the default homepage path at startup, which wastes a lot of time. Even if you select "Use blank page" in "Tools"> "Settings" on the IE menu bar, there will be a time delay. In fact, there is a quicker way to start IE browser. The method is as follows:
1. Right-click the blank area of the Windows desktop, and select "new"> "shortcut" from the function menu that appears later ".
2. Enter ["C: Program FilesInternet ‑eriexplore. EXE"-nohome] in the
But What surprised me was that, one of the following netizens replied that the sort method of Array itself in javascript was the fastest, faster than the fast sorting algorithm. At that time, I was very depressed, because it took a long time on the Sorting Algorithm, I forgot the sort method of Array.But is the built-in sort method in javascript faster than the quick sorting algorithm?Haha, I don't know after testing.Let's talk about the environment I

I would like to tell you that, although the author only uses one version for writing this book, the reader can be changed to several versions. Although there are many Linux versions, there are not many books required. You only need to find a few good books, understand the basic essence of Linux, and read every Linux operating system in the same way, this is the fastest way to learn the Linu

Problem descriptionin our daily life we often use 233 to express our feelings. actually, we may say 2333,233 33, or 233333... in the same meaning. and here is the question: Suppose we have a matrix called 233 matrix. in the first line, it wocould be 233,233 3, 23333... (It means A0, 1 = 233, A0, 2 = 2333, A0, 3 = 23333 ...) besides, in 233 matrix, we

This book was moved between the lab and the dormitory. One was CERNET, and the other was Nb's Netcom. To install something, we had to manually change the new software source!
It is estimated that you will be worried about moving between different networks!How can I know which is the fastest software source for my network?How can I automatically change the software source eas
How can I use the simplest and fastest way to determine whether a BMP image is a black/white image? It is too slow for me to analyze the full image scanline. Is there any direct function to do this? Delphi/Windows SDK/API

Thank you!
Look at the file header structure of BMP ..It contains information about color bits. If you do not have such information, search for it.

register modifiers that really work depends on the machine that runs the program, and any extra register modifiers are ignored by the compiler. In some cases, saving a variable in a register will slow down the program. Because the occupied registers can no longer be used for other purposes , or the variable is not used enough, it is not enough to load and store the additional overhead of the variable. The early C compiler does not keep the variable in the register unless you command it to do so

A few questions can be seen from above.
Running programs on Linux platforms is generally faster than on Windows.
Programs compiled under Windows VC generally run faster than MinGW (MINimal Gcc for Windows).
The VC is not sensitive to CIN canceling synchronization or not, and the efficiency is the same. In turn, the MinGW is very sensitive , 8 times times the efficiency difference.
Read is a Linux system function, MinGW may have some ki
