Check top again and pay attention to the %CPU line and how many tasks are running and how many are sleeping.
Hi there,
There is 1 running and 97 sleeping and the %CPU line is almost like last time. Almost all are 0.0% except the one in the middle that says ID which is around 90-100% and the next one called WA jumps up to 25-30% alot.
Found this
but there is no explanation for the middle stats called ID which is on about 100% all the timeQuote:
2c. CPU States
The CPU states are shown in the Summary Area. They are always
shown as a percentage and are for the time between now and the
last refresh.
us -- User CPU time
The time the CPU has spent running users' processes that are
not niced.
sy -- System CPU time
The time the CPU has spent running the kernel and its
processes.
ni -- Nice CPU time
The time the CPU has spent running users' proccess that have
been niced.
wa -- iowait
Amount of time the CPU has been waiting for I/O to complete.
hi -- Hardware IRQ
The amount of time the CPU has been servicing hardware
interrupts.
si -- Software Interrupts
The amount of time the CPU has been servicing software
interrupts.
st -- Steal Time
The amount of CPU 'stolen' from this virtual machine by the
hypervisor for other tasks (such as running another virtual
machine).
id is idle.
What is the load now?
75% Idle and 25% iowait. Trying to install postfix from webmin. Takes forever :)
2.36 - -2.16 - 1.82
I get Iostat command not found - I will try install sysstat
Here are the output from iostat
It says

I wonder if there is a chance that the disk partitioning I did before the install may have caused some of this ?
in that case here is the output of fdisk -l

Run top while trying to install something and watch the output. It should tell you what is using the CPU.
As far your drives, they look like normal drives, not advanced format drives, so I don't think that is the problem.
