Hi Robert,

If you are looking for some guidance on hardware purchasing, we need to know a
few things.

1.) How many records per batch.
2.) How many operations per record
3.) Preferred operating system (gives guidance as to type of filing systems
available and cache peculiarities)
4.) Number of concurrent users who are querying the same tables being inserted
into.

What I am trying to determine from the above questions is how much actual disk
activity versus disk thrash is going on and getting an idea about processor
requirements.

We insert GB's of data a week into our IB 5.6 database (yes we still have not
upgraded our workhorse machine). And that system is a realtime database
being queried by multiple IVR and SSI boxes from three cities in two separite
provinces.

We process billing and customer service control from our system with CSR's and
administration personel accessing it continuosly.

When you say your system is optimized and slow, I must really get alot more
details in order to help you.

best regards

Dalton
