its icon in Windows, and its out of box experience (OOBE) which is what happens when you run WSL for the first time. You’ll notice that theoobe_commandoption points to a file which is a Linux executable, meaning you can set up your full experience just in Linux if you wish. As...
This file contains the maximum number of memory map areas a process may have. Memory map areas are used as a side-effect of calling malloc, directly by mmap and mprotect, and also when loading shared libraries. While most applications need less than a thousand maps, certain programs, particul...
Beginning with MySQL 8.4.0, the deprecated mysql_native_password authentication plugin is no longer enabled by default. To enable it, start the server with --mysql-native-password=ON (added in MySQL 8.4.0), or by including mysql_native_password=ON in the [mysqld] section of your MySQL co...
gprof 的一个问题是它忽略了像 I/O 这样的阻塞时间。 由于你的程序在使用alloc_mmap(直接或间接)它是将一个文件映射到内存,所以它是在做I/O,这往往是一笔不小的开销。 gprof 看不到它。 还有更多problems with gprof. 如果你在 linux 上,你可以尝试像Zoom这样的分析器. 它按挂钟时间采样,因此它不会对 ...

进程中数据访问和内存分配时用到的地址都是虚拟地址。比如说在某句代码中访问变量,在链接时这句代码中到变量就会被修正为虚拟地址;比如使用malloc函数申请内存时,底层是调用mmap申请页面,本质上申请到的不是真实到物理内存而仅仅是虚拟内存。 Linux把进程载入内存准备运行到时候,是将其按照分页的方式存储,目的是减小外部...
