Hi Chaps,
I've upgraded a server running our database connection pool software from etch
on 2.6.18 to lenny on 2.6.26 and I'm now seeing intermittant high load averages.
I don't see anything CPU or IO bound on the machine using top and vmstat, and
I'm absoloutely baffled by it. Normal load

Nothing there. All seems fine.
Also,
check I/O
the other day I was moving several gigs of files from one ide drive to
another on the same ide chain (the secondary channel is broken) and my load
average went up to around 7 (no, not 0.07). The machine would become
unresponsive for several seconds at a time. This is a uniprocessor machine,
Have you checked your dma settings? hdparm/hwtools?

Is this normal? I don't seem to remember having ide performance issues like
this before (this is a new install).
This is normal if dma is not enabled.
It isn't enabled by default in Debian.
To enable it install hdparm and then
run hdparm -d1 /dev/hdx as root
where x is either a,b,c,d
Or just get hwtools it creates a basic init.d script where you put your
hdparm flags

Just a question: Is there any reason in particular for a Debian
Box keep its load average always over 6?
It is a AMD Athlon 750 Mhz with 256 Megs of RAM, running potato
and 2.2.19, compiled to run on i686. It has the Patches Debian
puts on the stock kernel, and the new-style raid patches,
what is running on it? have you checked top for processes?

that? Maybe you where running a

High load average means you've got more requests than you can handle.
But the actual efficiency of servicing of requests is not considered.

Load average is not an indication of how busy the CPU is. A busy CPU
