Sometimes my servers will show a high load average in the "top" program (e.g. load is ~10 on a 4-core machine), but the actual CPU usage isn't particularly high.
I assume the issue is that there are many I/O-intensive jobs running. Is there any easy way...

That in certain contexts high load doesn't really mean the system is trashed.

If you have.
Mpstat will show high values in ithr for the CPU's handling any NICs or HBAs, and a correspondingly high sys time.

That's probably a NIC's interrupt overhead.

I have a RAID 1 setup averaging 40 - 60 I/Os per disk and 0.5 average disk queue length. According to BOL example below, this is not a bottleneck.
Disk Reads/sec 80
Disk Writes/sec 70
Avg. Disk Queue Length 5
In that case, you are encountering (80 + (...

The Disk Reads/Writes data in itself wouldn't (to me) make sense to have a specific high I/O-discussed.aspx
As I read your question, you want to know how many IOPS (IO's per second) is high.

I have a high end Mac pro, but one thing in is that I'm unhappy with is a DVD drive. It's a Hitachi GH41N. Apple calls it a "superdrive", but it's anything but. The damn thing makes an amazing amount of noise, and isn't too fast either.

For various reasons I am looking at used Q7s at the moment to replace a 2002 S6 Avant.
The petrol Q7 has the same gorgeous sounding V8 engine as the S6 but given the fuel consumption of the older car I dread to think what an extra 600kg would do to it...

This way, if anything does go wrong, it's cheap and easy to fix .
Is there really such a thing as 'too high'? If a car has been driven sensibly and maintained a high mileage car, then try going for something mechanically simple.

It's also fairly high cost though, as you're using.
Amazon EC 2 is definitely high bandwidth and high performance and has supported Windows Server (2003, there is an AMI (the install file used for each OS) for that .

There really is no such thing as "bad high load" unless.
