Part 1: memory usage, special effects and APIs Thoughts on memory usageLet's think about how to use the 3D graphics card memory and how to use it in the future. Today, most 3D graphics cards handle 32-bit color, 8-bit red, 8-bit blue, 8-Bit green, and 8-bit transparency. The red, blue, and green colors of these combina

The program exits after normal execution. the SQL Server occupies 1.7 GB of memory and is not released. For fear that other applications on the server may be a

Today, Kingston's 1g memory stick is ready. In addition to the original 1.5 m memory, a total of GB memory is allocated, and MB is used as the virtual hard disk. The swap files, temporary system files, and temporary webpage files are all placed on it. It's really cool. It's faster to open files and browse the Internet, especially for

Problem: memory usage Someone wrote a function to convert integers into strings: Char * ITOA (int n){Char retbuf [20];Sprintf (retbuf, "% d", N );Return retbuf;} If I call this function: char * str5 = ITOA (5), what is the result of str5? Answer analysis: The answer is uncertainty. We can be sure that it is definitely not the "5" we want ". The retbuf is defined in the funct

assigns the address of A to P. To copy the contents of a, you can use the library function malloc for p to request a piece of memory with a capacity of strlen (a) + 1 characters, and then use strcpy for string copying. Similarly, the statement if (p==a) comparison is not the content but the address, should be compared with the library function strcmp.Array...Char a[] = "Hello";Char b[10];strcpy (b, a); Cannot use B = A;if (strcmp (b, a) = = 0)//canno

In the last two weeks, the memory of the DB server has not been used up, and 32 GB is used. As a result, the memory usage has been around 4 GB, which is really confusing. Normally, around 17 GB should be used. After troubleshooting for half a day, it turned out that awe didn't restart the service after it was turned on. It was really too difficult, so I had to fi

We are concerned about how to optimize memory management, improve memory usage efficiency, and increase the running speed as much as possible. The following describes how to improve memory usage and optimize memory management in w

The Linux server allocates real and virtual memory to the processor and manages memory usage through swap. Understanding the Linux memory type and how the processor shares memory helps optimize memory

Some web pages do not look big, but they are very slow to open. Some web pages are long but smooth to use, which affects the memory and CPU usage of users' computers. Browser problems may be affected by the memory processing problems of their respective browsers, but there is almost no way to control them. For Windows: middot; IE series, refresh is not much coll

The PHP built-in function memory_get_usage () returns the amount of memory currently allocated to the PHP script in bytes (byte). In the actual development of the web, these functions are very useful, and we can use it to debug PHP code performance.The Memory_get_usage () function returns memory usage, the Memory_get_peak_usage () function returns the peak

Through buffers, you can reduce the numb

When the number of concurrent TCP connections for a server is timed at 100,000, we are interested in how much memory a TCP connection consumes on the operating system kernel. The socket programming method provides interfaces such as SO_SNDBUF, SO_RCVBUF to set the read/write cache for the connection, and Linux also provides the following system-level configuration to set up the TCP memory

Using the top tool, we can see that SuSE Linux has a high memory usage, which may be more than 97%. I know this is a Linux memory usage mechanism. First, we can manage the entire memory, when necessary, it is allocated to a single process. However, if I need to check the rea
