I think that if your CDROM drive or CD is bad or you have dust on the lens of CDROM drive the system will try to correct the problem by making several reads on the same sector of the CDROM. 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 <yuri@tsoft.com> 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.
