Build high performanceASP. NETSite Chapter 7 How to solve memory problems(Previous)-Managed Resource Optimization-Analysis of the garbage collection mechanism This chapter describes in detail how to solve the performance problems caused by memory problems.. NetThe kernel is analyzed, and then a solution is provided.ArticleAnd strive to do the following. Th

Linux Kernel address space partitioning Typically, the 32-bit Linux kernel virtual address space is divided into 0~3g for user space, 3~4g for kernel space (note that the kernel can use a linear address of only 1G). Note that this is a 32-bit kernel address space partition, and 64-bit kernel address space partitioning is different. Typically, the 32-bit Linux kernel virtual address space is divided into 0~3g for user space, 3~4g for kernel space (note that the kernel can use a linear address o

Deep understanding of Java Virtual Machine: JVM advanced features and best practices (in-depth analysis of JVM Based on issues such as memory management and high concurrency) Provides a comprehensive and in-depth analysis of JVM based on core content such as memory management, execution subsystem, programming compilation and optimization, and efficient concurrenc

and memory consumption;The CPU can be judged directly in the top of the CPU%us value can be, usually under 50% is normal, once more than 60% or even high to 80-90 and stable, then there must be a problem;When judging memory, it is important to look directly at the first line of mem: The used value is not accurate, because usually after a period of time, this val

Overview of memcached Memcached is a high-performance distributed memory object caching system for dynamic Web applications to mitigate database load. It improves the speed of dynamic, database-driven Web sites by caching data and objects in memory to reduce th

generation, and the meta-space is stored in the operating system's local memory, which is a lot of threads, each thread has to use a bit of space, each thread is assigned a arena, each 64MB, will cause a huge virtual address is allocated.Summarized as follows: Virt High is due to the allocation of too much address space. Generally do not care too much virt too

This article introduces the solution for MySQL to occupy a very high virtual memory. If you need to learn, refer to this article. This article introduces the solution for MySQL to occupy a very high virtual memory. If you need to learn, refer to this article. Mysql consumes 700 mb of

The previous article introduced the online application of one of the troubleshooting: High CPU occupancy, this article mainly analyzes the high memory footprint troubleshooting. Java developers often encounter the following two kinds of exceptions: 1, Java.lang.OutOfMemoryError:PermGen Space 2, Java.lang.OutOfMemoryError:Java heap space To explain these two excep

generally divided into seven stages: creation, application, invisibility, inaccessibility, collection, termination, and release.Creation phase: Let's take a look at the following two sections of code:Test1:For (int I = 0; I Object obj = new Object ();Test2:Object obj = null;For (int I = 0; I Obj = new Object ();The two pieces of code have the same functions, but it is clear that test2 has better performance than test1, and the memory

UIWebView memory consumption is too high, crashes, memory overflow, the need for friends can refer to. In the project where the emulator runs UIWebView read Local magazine, no problem, the real machine test often crashes with memory overflow.I checked the data. Because of the memor
