Hi Eduardo,

Try running kernel-hugemem instead of the normal kernel, I recently
had similar problems to you which were fixed by running
kernel-hugemem.

I upgraded the RAM in a machine from 2gb to 4gb and it ran really
slowly with the normal kernel, but fine with kernel-hugemem

yum install kernel-hugemem

rebboot and pick kernel-hugmem on boot.

Good luck,

Rhys

Starting a new thread here...

Speaking of kernel-hugemem, I'm now curious - I've seen the term
before but never gave it much thought, thinking it must be for
those huge servers with 16 Gbytes or more of ram.

Rhys comment about using kernel-hugemem on a 4GB system has now
prompted me to ask at what point does one go or should go (or
need to go) to the hugemem kernel?  We have a couple of systems
at 4GB and will probably get more systems with even more memory.

And what were your metrics for slow running vs. fine running?

Thanks!
- Larry
