This paper describes an exokernel system that allows specialized applications to achieve high performance without sacrificing the performance of unmodified UNIX programs. It evaluates the exokernel architecture by measuring end-to-end application performance on Xok, an exokernel for Intel x86-based computers, and by comparing Xok's performance to the performance of two widely-used 4.4BSD UNIX systems (FreeBSD and OpenBSD). The results show that common unmodified UNIX applications can enjoy the benefits of exokernels: applications either perform comparably on Xok/ExOS and the BSD UNIXes, or perform significantly better. In addition, the results show that customized applications can benefit substantially from control over their resources (e.g., a factor of eight for a Web server). This paper also describes insights ab... | | volume: | 31,5 | | series: | Operating Systems Review | | note: | Published as Proceedings of the Sixteenth ACM Symposium on Operating System Principles (16th SOSP'97), Operating System Review (OSR), volume 31 | | month: | jul # "~28 | | annote: | M.
