If the UNIX file system is not "real UNIX" but merely a front-end to the Mac HFS software, then the single-threaded nature of HFS could be expecvted to present extreme performance obstacles, since only one process's file system request can get serviced at once, and the rest are sleeping. I don't have an A/UX to play with, but if it runs Mac disks, then it is almost surely not a real UNIX file system. -- Tim Maroney, {ihnp4,sun,well,ptsfa,lll-crg,frog}!hoptoad!tim (uucp) hoptoad!tim@lll-crg (arpa)
