Did you know, final

I started with multi-gb size XML files that would cause out-of-memory exceptions. After I resolved that issue (by using
XmlTextReader/XElementinstead ofXDocument), it was taking over 20 minutes to process the sample file set (434,000 rows). This is where I was on Friday. I added some TPL love and got it down to about 12 minutes. I reworked the target tables. At first, I was creating a single monolithic flat table, and a lot of data was being repeated for every record. I created two tables (one that holds the repeating data, and one that holds the unique data), and got it down to just a little over 6 minutes. This code will replace a Perl script that: 0) Creates a bunch of smaller XML files, probably so it doesn't run out of memory 1) Took over an hour to process the same set of sample files. 2) Did not return all of the data (because the stakeholder doesn't really need it) Added benefits: 0) My code can process ZIP (extracts NESSUS files from them for processing) and bare naked NESSUS files 1) Processes multiple files with a single execution 2) Puts ALL of the data into the database Caveat: Because of the limited hardware the app will actually be running on, processing time will take longer (because of the TPL's default behavior), but not significantly so, and CERTAINLY not take an hour. It's been a good weekend. :)".45 ACP - because shooting twice is just silly" - JSOP, 2010

Well, I was asked to do it if I had time, so... I don't really care if it's used or not. Pretty much everything I've ever written for the government is no longer used for the very reasons you listed. I've kinda GOTTEN used to it. I see it as a learning experience, especially due to the large XML file stuff I had to work around.

M.D.V. ;) If something has a solution... Why do we have to worry about?. If it has no solution... For what reason do we have to worry about? Help me to understand what I'm saying, and I'll explain it better to you Rating helpful answers is nice, but saying thanks can be even nicer.

Nope - there were several challenging aspects to the project, and I enjoy a decent programming challenge.

That's the reason I'm glad I got out of defense contracting. Of the last two projects I did for the Air Force in he late 1980's, one took over ten man-years to develop and was used for two weeks. The second was a bit smaller, taking about 3 man-years, but was never used at all. The only thing worse than when they call your baby ugly is when they are indifferent to it.

Not suggesting this is the case here. :-) Those time figures speak for themselves.

The voice of the experienced software developer. Once said (by me) to a younger developer who was commiserating that none of the stuff he's working on will ever be remembered by anyone: "Sorry to disappoint you Michelangelo, but we're not building cathedrals."
