mariadb-5.5.34-winx64.zip

MariaDB数据库管理系统是MySQL的一个分支，主要由开源社区在维护，采用GPL授权许可 MariaDB的目的是完全兼容MySQL，包括API和命令行，使之能轻松成为MySQL的代替品。在存储引擎方面，使用XtraDB（英语：XtraDB）来代替MySQL的InnoDB。 MariaDB由MySQL的创始人Michael Widenius（英语：Michael Widenius）主导开发，他早前曾以10亿美元的价格，将自己创建的公司MySQL AB卖给了SUN，此后，随着SUN被甲骨文收购，MySQL的所有权也落入Oracle的手中。MariaDB名称来自Michael Widenius的女儿Maria的名字。

指令集时钟周期

ASM为Assembly的简写，ASM指令的含义为汇编指令（泛指Intel 80X86 CPU中的指令集）。 ASM指令是为编程人员编写程序准备的，编译器将会把ASM指令真正的翻译成机器代码（能控制CPU做出操作的代码）。 ASM至今运用广泛，2015年所有的个人电脑，大型服务器绝大多数使用ASM指令集。 ASM的优点在于指令广泛和丰富，处理大型数据游刃有余，但是缺点也是显而易见的，由于指令的长度不等与指令的复杂，其耗能大，CPU体积也大。

This could result in rates being 0 or negative when they should not be. GitHub issue: rabbitmq-server#1340 Stats emission could prevent queue mirrors from performing garbage collection and consume memory even when they were empty. GitHub issue: rabbitmq-common#220 (continuation to rabbitmq-common#196) RABBITMQ_SCHEDULER_BIND_TYPE and RABBITMQ_DISTRIBUTION_BUFFER_SIZE now can be set via rabbitmq-env.conf.
