So you appear to be saying that the cause in the slowdown is the OS and
not the version of the linker ? Did you try using the 2.16.91.0.6-5
version on FC4 ? If so was it still < 10 seconds for the link ?
Have you tried using any system profiling tools to find out what is
going on ? (vmstat, oprofile, etc)
Do have other background processes running on the FC5 machine that you
do not have running on the FC4 machine ? Are you using NFS mounts ?
Anyway really if this is an OS issue, you ought to try asking on a
Fedora list.
Cheers
Nick
