[freeside-users] freeside - too slow

[Victor]

I use freeside 1.4.1 with apache::asp on a dual processor sempron 2.2Gh..
It works too hard in strange conditions.

I try to load the main page and the processor is at 100% - http process 
takes it all.
The page is just some html.
After I load it a few times works better, but after another few minutes 
it takes all the processor again.

How can I make it more efficient?
How can I debug it? - I want to know what is heapening when the 
processor at 100%.

I have installed the last versions for  freeside modules.
