NFS is also a 'lot of interrupts because of small data packets' type of application, just like your favorite full screen text editor. I can't just now comment on how far this similarity holds; we're expected to sort this out in about a year's time (BTW, there are other reasons for not wanting to use NFS: e.g. the system administration overhead (people time) that comes with it). -- Toon Moene, SARA - Amsterdam (NL) Internet: TOON@SARA.NL /usr/lib/sendmail.cf: Do.:%@!=/
