> One friend of mine wrote code that was 1000 times faster than the people in the next cubicle over

And did that 1000x speedup make a difference to users? Are we talking about an on-click event that now took 10μs instead of 10ms? Was this a 1000x speedup in a hot critical-path bottleneck, or was it an already quick in-memory post-processing operation that fired after waiting 30 seconds on a sluggish database query?

Sorry to doubt so much, but the vast majority of times someone boasts about a speedup like this, it turns out to be done for bragging rights rather than for the benefit of the project. A 1000x speedup is only impressive if you can show that the time you improved upon was actually a problem.
