I am not a linux wizzo, so please excuse the ignorance that may follow.
Red Hat 7.3 kernel 2.4.2
I recently had to do a hardware replacement for an aquaintance on his Linux machine. The hardware went from an AMD1.3 GHz to Intel 3.0GHz Hyper Threading LGA775 socket on an Intel 915GEV Eatonville maiboard with 3 Gig memory.
The boot drive remained the same (had to master up with CD rom as mainboard only has 1 IDE slot.
The data drives are the same on a Promise ATA100 Raid controller.
An application called Hercules (mainframe emulator) runs on the machine.
Used previous LAN adaptor as i cannot find Intel 1Gig drivers.

Everything behaved on startup and Linux reconfigured devices and asked to remove old devices.
A USB error pops up on startup, but we not too concerned yet.

Problem:
Power up to linux login is about twice as long.
From login to full availabilty of mainframe emulator is about four times as long.
Within mainframe emulator the MIPS indicator indicates 1million MIPS, where old AMD was at about 5Million MIPS.
Mips also jumps between 1Million and 5Million sporadically.

Where to now. Do we reinstall Linux? Do we upgrade to newer Kernel?
Anyone got any ideas.
I will pop across to him and look at the messages file and see if there is something there.

Thnx
