Fixed processes are suitable only for system server processes such as the file server , window server etc . since the majority of context switches involve these processes 固化进程只适用于系统服务进程,例如文件服务,窗口服务等。因为绝大多数的上下文切换都包括了三个步骤。
When excessive context switching is present , lightweight pooling can provide better throughput by performing the context switching inline , thus helping to reduce user kernel ring transitions 如果出现过多的上下文切换,轻型池可以通过上下文切换内联化,从而降低用户/内核环的转换频率,达到提高吞吐量的目的。
Too many threads in a process tend to slow down the server because of extra context switches , causing the operating system to spend cpu cycles on maintaining threads rather than processing requests 因为额外的上下文交换导致操作系统将cpu周期花在维护线程而不是处理请求上,所以进程中有太多线程往往会降低服务器的速度。
The sql server database engine security functionality includes highly granular authentication , authorization , and validation mechanisms ; strong encryption ; security context switching and impersonation ; and integrated key management Sql server数据库引擎安全功能包括高粒度身份验证、授权和验证机制;增强加密;安全上下文切换和模拟以及集成的密钥管理。
