[Demiurge]

Completely agree with the sentiment. I think most often it is inadequate default configuration that bottle-necks somewhere, that never got tested with more than a handful of users at a time. Going to a hundred highlights some bugs. going to 1000 others. On the other hand, I have worked on a project for USDA and they had 10 year old servers running 15 year old software and did not allow any system administration, while the system admins were some unknown government employees completely inaccessible.

I have had to build python distribution completely in home/user-space in some cases, working on conservatively managed servers.
