.... OS primitives can reduce the cross domain invocation cost to within a single order of magnitude of that of a normal function call [16, 17] While this still constitutes significant overhead on primitive operations, in terms of overall system execution times this is often reduced to a few percent [18,19]. Still, the overheads may be too high for component software with high invocation frequencies. However, software only protection has its cost too: run time checks cannot be avoided unless restrictive programming models are imposed, and the size of the trusted computing base (TCB) dramatically ....

....and memory management are provided by (possibly privileged) servers. Whilst this approach does provide a more flexible method of OS design, the additional modularity and protection can increase the overheads of communication between applications and the various servers. However, previous work [Hartig97] has suggested that with careful optimisations, the cost of such communication can be comparable to a traditional kernel based system. A more fundamental problem with the microkernel approach is that it makes accurate resource accounting even more di#cult than in the case of a kernel. Let us ....
....measure a null invocation using two standard Windows NT IPC mechanisms. J Kernel Null LRMI (Local Remote Method Invocation) measures a call through a J Kernel Capability [Hawblitzel98] running under a Microsoft JVM and a Sun JVM. L4 Null IPC measures the time for an IPC in the L4 microkernel [Hartig97] It may be seen from Table 7.3 that Rcane services are substantially faster than IPCs on Windows NT or Nemesis; they are comparable with IPCs over the J Kernel. J Kernel and Rcane both take a similar approach to protection, by employing multiple disjoint sets of data in a single address space, ....

....not insist on the principle of least privilege : a mobile code should be granted the most restrictive collection of capabilities required to perform its legitimate duties, and no more [5] Designing a protection policy is much more complicated in Palladium than in our approach. LRPC [1] and L4 [6] attempt to minimize the overhead of interprocess communication in traditional operating systems. Since interprocess communication inherently requires to switch computing resources, our model based on fine grained protection domains will over perform interprocess communication. If a more efficient ....
