Java Memory Analysis 2__java memory analysis

–gccapacity: Can show the use and occupancy of three generations (Young,old,perm) objects in VM memory, such as: PGCMN Displays the minimum perm memory usage, PGCMX displays the maximum amount of memory used by Perm. PGC is currently the newly generated perm memory footprint, and the PC is but the previous perm memory footprint. Other can be based on this analogy, OC is the pure amount of old. [Root@localho

"Go" how to avoid oom summary

Original address: HTTP://WWW.CSDN.NET/ARTICLE/2015-09-18/2825737/3Reduce the memory footprint of an objectThe first step to avoiding oom is to try to minimize the amount of memory that is allocated to new objects and use lighter objects as much as possible.1) Use more lightweight data structuresFor example, we might consider using traditional data structures such as Arraymap/sparsearray instead of HashMap. Figure 8 illustrates how HashMap works, and,

running QQ and mail client software, the normal use of Photoshop. Then when you turn off Photoshop and switch songs, there is a noticeable lag, and it's clear that the efficiency of all common software is significantly reduced. Open Task Manager to see the difference between memory footprint and not closed. The first 43 processes that were not closed are probably 800-850MB memory footprint. Use memory col

Linux process automatically monitors bash shell scripts

The purpose of this script: Mainly used to monitor the Linux VPS server load and memory footprint, such as MySQl, PHP-FPM, when the load or memory consumption reached the set value, it will automatically restart the process to avoid downtime.

What makes Firefox a "Memory Killer"?

From Firefox 41 to Firefox 29, Firefox has struggled to reduce its system resource footprint, especially in memory footprint control. But there are still a lot of users complain that Firefox consumes large memory, or even call it "memory killer." Does Firefox really have such a big ability? In recent days, Mozilla's official blog has revealed the truth about the Big memory

The most recent project encountered a problem with a very high memory footprint when multiple pictures are loaded at the same time in WPF. Problem background: Load multiple pictures in one listview, note: We need to load the picture resolution is very high.

(BITMAP) argb_8888/rgb_565/alpha_8/argb_4444 detailed

Sometimes you see other people using bitmap to use argb_8888/rgb_565 parameters, so what are these parameters? What is the impact on bitmap?They are the four enumeration types of Bitmap.config.(The ARGB are alpha transparency and red, green, blue three colors respectively)argb_8888:8 bits are used to record 4 values, so each pixel occupies 32 bits.argb_4444:4 bits are used to record 4 values, so each pixel occupies 16 bits.rgb_565: Use 5-bit, 6-bit, and 5-bit to record RGB tri-color values, so e

IOS Debugging Tools

Instrument The xcode5 introduces a debug meter, which intuitively shows the CPU and memory usage of the application. Run a program and click on the Dashboard bar. You can find that when the program is running, the debug navigation panel displays the CPU and memory footprint in a histogram and updates the consumption data in real time as your app does. It is important to note that the data in the Debug navigation panel is calculated based on the a

Android high-efficiency memory 1: How much memory a single picture occupies

in memory optimization, we found that in addition to resolving memory leaks, the only thing left was to reduce the actual memory footprint. In the app, most of the memory may be occupied by our pictures, so reduce the memory footprint of the image can bring a direct effect. This article simply introduces how much memory a picture occupies, let's assume that we have a picture of * * , the image occupies a s

PHP unset free Memory Use example test

output unset () consumes memory minus unset () and if it is positive, then unset ($s) has destroyed $s from memory (or, after unset () the memory footprint is reduced), but I am under PHP5 and Windows platforms, The results are:-48. Does this indicate that unset ($s) does not play a role in destroying the memory occupied by the variable $s? Let us make the following example: $s =str_repeat (' 1 ', 256); Produces a string consisting of 256 1$m =memor

Skillfully using footprints to find out the chain resources

A few days ago bought the Zac "seo actual password", from which to learn what footprints is, the following to share how to use footprints to find out the chain of resources. Footprints can be understood as footprints, traces. For example, a common program, templates, and so on, will leave the same traces, we can use this trace to crawl the site to meet these characteristics. Why crawl these sites? What's the use after crawling? These should not be explained. Take "powered by" this most basic
