CentOS - Aug 2014 - CentOS 5 takes one second holding each keyboard key until it shows.

I used CentOS 5 for years. Suddenly, it takes one second holding a 
keyboard key until it shows on the screen:

I copied the CentOS 5 /etc/X11/xorg.conf to CentOS 7 (on the same 
computer) and rebooted - no effect. I copied the CentOS 7 
/etc/X11/xorg.conf.d/00-keyboard.conf to CentOS 5 and rebooted - no 
effect. I tried different CentOS 5 xset settings, I tried an IBM Soft 
Touch and a Logitech keyboard using different cabeling. What might 
resolve this new one second delay for each CentOS 5 keyboard key? What 
might have caused it?

ThanX

 Did you change or update any hardware recently? This might be a bit
 far-fetched, but I observed behaviour like this when connecting a new
 monitor to a machine running CentOS5 through DVI. I don't recall the
 details, but the monitor created some kind of interrupt issue that the
 CentOS5 kernel (5.4 - 2.6.18-164.15.1.el5) couldn't handle. Symptoms
 were slow-responding keyboard and jerky mouse.

 If it's something like this, you should see it in the logs.

Dumb question: have you tried a second keyboard?

Is this system accessible via SSH?
Does the behavior only happen when using the physical keyboard?

Might it be out of physical memory (RAM) and swapping violently?
Disk thrashing of this sort can cause rather irritating delays.

Or maybe a failing or failed drive?  (Assuming you could have a hardware or
software RAID setup).
