Could some of the list members please shed more light on the
performance differences between PERC 4e/Di and PERC 4/DC. I read somewhere
on the net that the reason why PERC 4e/Di performs so poorly as compared
to other PERC controllers is because it shares a common bus with other
devices. Most notably the VGA controller. Due to this bus sharing the
overall bus speed is reduced to 66MHz which causes a drastic slowdown in
Has some member of this list ever noticed such a performance difference.
Also, will us upgrading to a PERC 4/DC PCI-Express controller help.
Thanks for all the help.
