100x slower would definitely be an issue. I am prompted for my sudo password probably 30x daily.

Come on, wtf? Your computer can literally emulate another architecture in real time and you think sudo 100x slower would be humanly sensible? Computers literally wait eons for human inputs in the majority of times.

I assume you actually think that sudo takes the time it does, but you just likely entered your password wrong and are made to wait deliberately through a sleep. Are we really that bad at ball parking code execution times?!

I just checked, and on the machine I'm sitting at 100x slower would mean it took 0.1s of CPU time.

How long does sudo take to load on your system. Multiply that by 3000, is it really a noticeable number?

Seems to float around 0.005s (using "time sudo -k" to avoid timing user input), so yeah, x3000 = 15 seconds. Very noticeable.

Or even the x100 from (G)GP, that's a half second. Sometimes spiking to a full second.

I have once seen a proposal to make any sudo call wait for 10 seconds before doing anything so that the person running it has a moment to thing about what they just did do (and have ~10 seconds to ^C cancel it).

The person arguing also brought up that normally anything needing sudo should be automatized so that should be fine.

I'm not doing enough system administration to judge if that is a sane idea or not ;=)

That assumes that sudo the executable taking longer would linearly increase the time when in fact your OS loaded the exe into memory, created a process, allocated memory and let it go. A significant amount of time was just that, nothing related to the program’s job.

I am seeing an average of 0.0008 over 100 runs on Linux (i.e. less than a millisecond).

Ah, fair enough, that's a bit high of a multiplier.
