So this takes system time and the whole system goes slower. Try different CDROM drive or different CD - this could solve your problem :) Ivailo Tanusheff Yuri Sent by: owner-freebsd-questions@freebsd.org 07/13/2005 10:54 AM To freebsd-questions@freebsd.org cc Subject why CDROM operations cause system to be slow and HD operations do not When I read something from CDROM my system gets visibly slow and HD reads/writes do not have the same effect. I think they both should have similar effect on system performance since multiple requests should just wait till completion interrupt and other processes shouldn't be affected.
