Or did already somebody do something like that? At least I found, that a single process (on 5.2-CURRENT-20040408) can be so rude that another process cannot even read 100Kbytes/sec (although usually I can read up to 20Mbytes/sec from my discs) [see change request kern/71833 (http://www.freebsd.org/cgi/query-pr.cgi?pr=kern/71833)]. -Wörner __________________________________ Do you Yahoo!?
