How to approach

Question

The following is excellent for getting the keywords from the
referer values stored in my db.
The problem is how to organize the results so I can use them
in a cfchart. Normally I would use a query of a query to output the
values but as everything is outside the db I don´t have a clue
how to go about this especially as I am going to be working with
grouping values (keywords) that I don´t know until the code
has executed. How do I do approach this? Thank-you

Sorry for the long delay in response; I was out on a much needed vacation. ^_^
So far we have only been running test cases using typical "production" data; duplicating images of an internal Linux ISO/source mirror host being one of the test cases. Some of our real research data contains a mix of both directories with large numbers of very small files and very large multi-gigabyte files.
RAID 6 was initially selected for our test case because it provides protection against a double drive failure, something we have had problems with in the past. I will need to repeat tests with RAID 5 to be sure, but I suspect that the performance problems we are seeing are not so much associated with parity computation as with some other factor.
The current NSS 300 data sheet 1GB ram and a Linux 2.6 kernel, so I was wondering about kernel tuning and/or how write buffering was handled. In any case, it does appear that writes are cached up to some memory limit after which writes are blocked until the cache is drained.
