In the relatively fluid* mid-90s at my second or third major contract at a trading bank we had an overnight batch on an Intel server which took, on a good day, about 8 hours to run. On a bad day it took about 10 hours - which cut into the traders day by about an hour. Traders being raiders (this was an autocorrect but I like it so it's staying!) there was much shouting of abuse when this happened but the IT bosses would not fund a newer/better server so the support desk just had to put up with it.
Cue my impatience and a visit to the Head of Desk to have words about the abuse my team were being subjected to by his team. I explained the issue - that IT wouldn't shell out for a new server - and he asked how much one was and how quickly one could be obtained. About £4k, says I, and six weeks via regular supplier/order process or about 2 hours via Tottenham Court Road. He handed over his credit card and £20 for the taxis.
Problem solved - although I got some abuse from the IT bosses for the out-of-process solution.
*i.e. JFDI was not entirely frowned upon.
