....process and invoked via a library linked with the application. However, this imposes significant overhead due to context switching. This cost can be reduced by running operating system servers in the address space of the kernel or by migrating threads between address spaces [Bershad et al. 1990, Lepreau et al. 1993, Ford Lepreau 1994, Lucco 1994] but these solutions would require substantial modifications to existing commercial UNIXes. The Slic prototype is therefore targeted at enabling extensions like those in the upper right No Protection or Protection and or Enforcement Needed Enforcement Required ....
....used with operating systems which are in common use today. Research is currently being done in the area of improving performance of user level operating system servers by running them in the same address space as the kernel, thus reducing context switching costs between applications and the server [Lepreau et al. 1993]. However, current approaches assume that server requests are made through Mach style ports. Our approach is more generally applicable to widely available standard UNIX operating systems. Projects which have attempted to make existing operating systems easier to extend are Protected Shared ....

....to the existing Mach 3 RPC mechanism were also reviewed. One such optimization is port buffers [10] a technique of grouping multiple RPC calls which can be performed on top of LRPC Mach3 and benefit from the improved RPC performance. Another Mach 3 RPC optimization reviewed was in kernel servers [11], which reduces RPC call latency by putting servers into the kernel s address space, limiting the facility to those with kernel access and defeating some of the benefits of the microkernel architecture. This work led to the exploration of the use of thread migration to speed up directed control ....
