[Web4lib] pcs running more slowly as time passes

[Jon Gorman]

This isn't really on-topic, so I'd suggest posting on syslib-l or
perhaps even code4lib.   I'll give some responses off the top of my
head since the questions already been asked....


 I could think of several reasons for this happening, although some
depend more on how this Juzt-Reboot works.  (Is it restoring from a
secured image somewhere, is it just hammering the drive every time,
how often is it "restored", etc):

1) The drives are going.  Have you run a disk check of some sort or a
utility like spinrite?

2) Ram is going.  Again, what diagnostics have you run on the
computers?  Any sort of memtest?

3) You aren't updating the images on the Juzt-Restore cards enough.
If there's some other machine on your network that is compromised,
these machines could be reverting to a clean slate, but then
immediately being compromised on startup by an virus/worm/trojan that
your anti-virus isn't recognizing.  Is there any odd network traffic?

4) Your image on the Juzt-Restore has a compromise on it already.  How
do you know it is clean?

If I had to guess, I'd probably bet on number one.  Drives don't last
forever.  In fact I heard some recent statistics that showed a large
number nowdays only last between a year or two, particularly in high
use settings.  How frequently do you replace yours?
