From the Windows Task Scheduler, their Data Extract runs at 12:00am daily but their GetFiles.exe runs every single minute indefinitely. NetStock says this is quick and non-invasive especially on SQL (is it?). Moira they have 2,000 SO headers, 18,000 SO detail rows, 18,000 items. Which history file does it check? Regardless I'm certain this is not the cause of their 11:15am extreme slowdown.
