I do notice a dramatic difference in ECN's response between my home computer and my work computer. Work has the s l o w one.

Since the work computer has many other issues, and the company has all manner of goofy quirks, I place the blame on IT's "witches brew" of computer controls.

That my employers' computer system actually is mentioned in the latest Clancy Novel (Threat Vector), I suspect that security concerns are the cause of the quirky IT stuff. (FWIW, Clancy did 'change the names' to suit his tale. That the employer had to pay a massive fine is a tale for another day).
