Is top showing that you really are using the 4 CPUs available?
Pressing the numeral 1 will toggle multiple CPU lines in top.
To display the CPU a program is running on first press 'f' then 'J' to add the
CPU in use column (P) to top's display.
What is your load average?
Does 'uname -a' show that you're running the SMP version of Debian?

To answer the questions from Randy and Chris and add more detail.
Koha was installed following these directions:
http://wiki.koha-community.org/wiki/Koha_3.2_on_Debian_Squeeze
and the install notes towards the bottom of this page starting at “Step:
Install Koha”
http://wiki.koha-community.org/wiki/Setting_Up_Koha_in_Virtual_Environment_%2B_Using_That_as_a_Development_Environment
The server is a virtual machine on ESXi v4.1.
It is the only virtual machine on the host ESXi server.
It has 4 CPUs dedicated to it, as well as 1GB RAM
Watching “top” it doesn’t use enough RAM to get to need to swap
Top shows:
opac-search.pl for however many tabs I open from the initial search screen
followed up with
opac-detail.pl
ping requests are <1ms
Machines are on the same physical network, just different subnets.
Thanks,
Jeremy

What version of koha are you running? Where did you download it?
I noticed that you went "through the examples on liblime.com".
If that is where you downloaded koha then you are not running the community
version of koha.
Regardless of what koha you are running, check the output of the command "top".
That should give you an idea of what is taking up time in the process.
Are all these machines on a local network? Is ping response between the
machines reasonable?

Subject: [Koha] Introduction and incredibly slow searches
Hello Everyone,
New to the list, new to Koha, increasingly frustrated :}
I’ve built a koha server for our in-house library which seems to have gone over
fine but I’m having issues with incredibly slow search response.
I’m running the latest stable koha-common 3.6 (updated a few minutes ago) on
Debian 6.0.3.
I have successfully entered in a record for one book. When I search from the
initial koha page it takes ~4 seconds to find this item. Then once the item has
loaded if I click one of the links for a searchable item (author, details,
etc.) it takes ~4-5 seconds for it to load. When I open all of these options at
the same time in new tabs it takes forever. It seems to be an almost linear
increase in the time it takes for the searches to complete. Also, each new tab
running a different search will continue to run until one has finished, then
once one has finished another will go. This process is ~4 seconds for each
search. Seems like all searches are in a very slow queue.
So for this example book I have in the system there are 7 items that are
searchable. If I go through and open each in a separate tab the total process
for all of this is 30+seconds.
I tried running a webserver load test with just 10 users clicking on a
different link each time the new page loaded and it failed horribly with an
average page load wait of 50 seconds
I really don’t know where to go to look for what’s causing this.
When I use the “browse by author or subject search”, the authority search
results page comes back in less than 2 seconds. Though it does show 0 biblios
records (no clue what that is)
I’ve gone through many example sites found here:
http://www.liblime.com/demos
And they don’t seem to have this same issue.
Any help. Thought, direction would be greatly appreciated!
Thanks,
Jeremy
