Hello all I experienced a problem I never encountered today nor not prepared for. I have a 
NAS device serving as a NFS file share to a bunch of linux 7.2 machine's. I just recentely upgraded
to NAS server to a recent release of redhat(7.1 the reason being is because of the company who
released the nas device has only tested redhat 7.1 and they use reiserfs). Anyway after upgrading the
machine I had the pleasure of switching the machine over to gigabit. During the course of the week
I had a lot of performance problems. The load average on the machine would spike to 9.00. I didn't
understand why the load was so high it was never high before. I attempted to check

1) Network throughput
2) IO throuput 
3) Avaliable memory

Then when I didn't know where else to turn I called the company of the product and there 
response was that since you switch over to gigabit your network bandwidth has increased 10 folds
there for the faster the traffic the more instense the proccesor has to grind. 

After hearing that answer I realize I don't have a deep understanding of hardware. I have been
a sysadmin going on 4 years know and I realize I am lacking in

1) Unix kernel heirarchy
2) Device drivers
3) File system structure
4) Newtwork issues

Is this stuff you learn from expierence or from a book. I think I have reached a cross roads 
where howto's and books aren't enough anymore for me to learn. But I am not sure where
to go to get a deep understanding of such concepts. I guess I should ask how does one begin
to understand such topics?
