Whatever you did, it is an insane difference. Orders are now running in seconds instead of long minutes. Sweet!!
Nice job, Sean. Yeah, hearing from the end users that you made their life better is a nice thing to hear every once in a while.
It's always good to hear that you've made the users' lives better. "I don't know what you did, but it's so much faster now". Of course, every so often the silent response from me is "I don't know what I did because I haven't touched it but if you're happy, I'm happy."
Not forgetting the classic from the users, after hours of you working on something for them in the background: "Never mind, it's fixed itself!"
"Knowledge is of two kinds. We know a subject ourselves, or we know where we can find information upon it. When we enquire into any subject, the first thing we have to do is to know what books have treated of it. This leads us to look at catalogues, and at the backs of books in libraries."

I wonder, would the great Samuel Johnson have replaced that with "GIYF" now?

Did you find some indexes were missing?
Haha I was actually initially thinking something along those lines. But this software is...well...interesting. It turned out that they were storing an archive copy of the xml in a file for every single package. In addition they were also saving the dynamic sql that they generated for every single package. This folder had over 3.5 million files in it. No wonder it was so damn slow. Windows has to make sure every file name is unique, and with that many to parse through of course it is slow. I renamed the folder and created a new one with the same name. I found 3 other folders with the same kind of craziness going on. Today I am writing some scheduled tasks to clear this insanity out of these folders. Gotta love third party software that decimates a system like that. Sheesh!!! And since Ed Wagner will ask, no this isn't our ERP doing this. It is another choice piece of vendor work.

Hey, Sean. I don't remember that particular ERP ever doing such a thing, but it sounds horrible. It's a "choice piece" of vendor something, all right. 😀 3.5 million is more than enough to slow down any file system.
Sounds like a great find and fix. Keep the files for a short time and blast them. If you can't delete them outright because management "needs them for future reference", move them to an archive folder where they can live until the drive fills up and forces management to make a decision. By all means, get the long-running enumeration of files to be independent of the database.

I can think of 2 questions to ask the vendor.
Was this for testing?
Was it in case of a breach to see what was submitted?
They probably would never generate the volume needed to run into this in testing. So unless they did troubleshooting on site, it might be difficult to replicate.

Tuned a reporting query once that was running for 17+ hours, brought it down to 1.5 seconds. The day after I was asked if something had changed. I responded by asking "why do you ask?" with the reply of "no particular reason, just asking"

It is nice to have recognition of good work, but it is equally important to have some tolerance when things get tough!

It would have been far too obvious deleting just handful of records, had to be masked....

It wasn't the ERP that you have the "pleasure" of working with. It is the shipping system which is a separate but equally "interesting" piece of work. The utility will take all the files and zip them once a day and store them in another folder. Then it deletes them from their location. And finally will go to the archive folder and delete anything over a year old. So simple I really don't understand why more developers can't write this kind of thing into their software as it really isn't all that difficult. I wrote all three utilities in less than half a day. I had to use three different sets of logic because there are some files in each of these locations that need to be kept so the system will keep working.

It's not as simple as a super-verbose logging option set for troubleshooting, hidden away in a config file is it? Have been bitten by that in the past.

Many, many years ago as a computer operator at Ent Credit Union while working days on Friday and Saturday the phone would ring. The first thing I would do is walk over to the console and type 3 or 4 U's then answer the phone. Almost always the response from the teller on the other end was "Never mind, you already did it."
The U was to unlock their terminal (any terminal actually).

No, the tellers locked up their terminals by typing faster the terminal buffer could keep up. By the time they heard the beeps, they were already locked.

I wonder what was the reaction from that [third party].
Was there a mention of void warranty, contractual obligations, and stuff?

A few years ago, when I was getting ready for maternity leave, we hired a contractor to fill my position. While I was training them, I showed them how I start my morning (logging into all servers, checking the Job Activity Monitors on each, etc.) and their first complaint was "Why isn't this automated?". I suppose that's a valid complaint, but I explained my reasoning for doing it and told them if they had a better way, to feel free to come up with something.
So they built a program to scan the logs of several servers and output an email to the DBA team with the 25 most important daily jobs and their status. The email includes job name, date it last ran, and a little "light" to indicate "Done," "Running," and "Failed." Which was kind of neat but I never really liked it for some reason.
This morning I'm going through the Job Activity Monitors (because I'm awake earlier than the job runs) and as I discover a new job that failed and doesn't have notifications set up, it hits me why the contractor's automation bugs me so much. It doesn't give me a true feeling of the state of the server jobs. It doesn't auto-add new jobs, it doesn't cover all jobs, and the last run date is so small on it that I don't notice it half the time and might mistake a successful run from 3 days ago as a successful overnight run if I'm not paying attention.
Am I the only one who likes to actually look at the regular server tools to verify things are working and get a handle on what my day will be like? Or does anyone else feel like there's something to be said about just taking a few minutes out of the start of the day to make sure everything looks good?
