Performance of the World's Fastest Distributed Operating System

摘要

Distributed operating systems have been in the experimental stage for a number of years now, but few have progressed to the point of actually being used in a production environment. The Amoeba system was designed with high performance in mind. Some performance measurements of Amoeba are presented; comparisons are made with UNIX on the SUN, as well as with some other interesting systems. In particular, short remote procedure calls take 1.4 msec and long data transfers achieve a user-to-user bandwidth of 677 kbytes/sec. Furthermore, the file server is so fast that it is limited by the communication bandwidth to 677 kbytes/sec. The real speed of the file server is too high to measure. These are the best figures yet reported in literature for the class of hardware used.
