svchost high memory usage

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

are only taking up less memory2. When the request arrives, the thread pool allocates an idle thread to the request and processes the request into the thread3. When the thread pool pre-sets the number of threads that do not meet the requirements too much or too little, you can manually adjustBenefits of the ③ thread pool1. Reduces the number of times a thread is created and destroyed, and each worker thread can be reused to perform multiple tasks.2. You can adjust the number of threads in the th

that it does not meet your requirements. sizeof can only tell you the memory size occupied by the pointer. The memory pointed to by the pointer. If it is allocated by malloc, sizeof cannot be known. In other words, the memory allocated by malloc cannot be queried by the memory management module afterwards. Of course,

: IIS service manager ---- application pool ---- add your application and set the maximum memory. When the Program reaches the maximum memory, it will automatically restart. My problem is the same as yours, but my memory is 2 GB and the access traffic is high. Generally, I have to restart after 24 hours of operation,

The memory ing file allows us to reserve a memory area in the virtual address space of the Win32 process and map the target file to the virtual

And we will later analyze this persistence strategy is immature, so to turn off the VM function, please check your redis.conf file vm-enabled to No.Next, it is best to set the MaxMemory option in Redis.conf, which tells Redis how much physical memory is used to start rejecting subsequent write requests, which is a good way to protect your redis from using too much physical

as long as they are unreachable from the root process.The advantage of this approach is that the precision of managing memory is high, but the efficiency is low.+ +:Another common memory management technique is the use of counters, such as the COM model, which uses counter-mode management artifacts, which are low-precision rows (difficult to handle circular refe

I have made some optimizations on the memory usage of the program recently, and have achieved good results. I have summarized some experiences. I believe it will be helpful for you to write high-quality programs. The following discussion is not applicable to 64-bit systems for 32-bit systems. You often write a program, test it, and have no function problems. Whe

Linux memory mechanism-cache and bufferIn Linux often found that the free memory is very small, it seems that all the memory is occupied by the system, the surface of the memory is not enough to use, it is not. This is an excellent feature of Linux memory management, which d

because of its flexibility and high efficiency, C + + has always been one of the mainstream programming languages, but the allocation and release of its memory is managed by the programmer itself, which causes a memory leak when the program fails to release memory that is no longer used due to negligence or error.

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
