Okay, I've did some testing, and, it really doesn't matter much how you use it, as using a "pumping motion" (leaving a slight delay between each usage) or "pressing it as fast as you can" give both a direct boost to maximum speed, the item has a fixed usage time, and you can't double up on the boost.
HOWEVER, the most important thing, for efficient usage, is to always start your next boost before the speedboost effect of your previous boost has ended.
As a result, pressing it as fast as you can after 4 pump usages might give you the last boost closer to the end of the item, giving you a litle bit of extra distance, while still retaining the most control over your kart.
A final important thing to note is that unlike most other items, you can't pick up another item, while under the effects of the golden shroom.

I agree with George Stocker about using it to get through slower shortcuts, and also to knock around other racers.
However, my personal experience seems to suggest that giving it a bit of time in between presses of the [Z] button seems to help maximize the boost's effect.
Of note is one of the reasons why I think it does so: It makes it much easier to drive.
When you mash the [Z] button with the Golden Mushroom, the camera rapidly jerks in and out, generally having the effect of the player weaving all over the track.
Even if using the boost more slowly does slightly reduce overall speed (which I personally doubt)
it makes up for it by greatly increasing your ability to stay on the track.
Regardless, it still seems to work better with a delay even on a straight stretch of track.
It seems that when the boost is used, there is a short period of acceleration up to the maximum speed, and that boosting repeatedly incurs this acceleration period each time.
However, I cannot prove any of this, and it should best be viewed as a personal observation, and taken with a grain of salt.
If anyone can confirm this, please do so.
Hope
this helps! :]

Ideally you want to use it to get around a section of track that would normally slow you down; grass, the not-so-deep water, and gravel are just a few examples.
You also want to use it if you're a lighter weight character (toad, et.
al.)
against heavy-weights (Bowser, Wario).
As far as what is 'better'; it only lasts for a certain period of time whether you hit it once or 100-times, so I'd use it more quickly.

I think it is best to tap quickly.
If you go into single player mode and cycle the HUD using c - right you'll eventually come upon a speedometer display.
It is apparent that a boost is relatively short lived; it is ineffective long before the exhaust color returns to normal.
If you play around with it in SP you should eventually find a rhythm that maximizes control ease and speed.

We just did a lab with MK 64 in my physics class, and our data seemed to indicate that giving the boost just under a second and a half before boosting again yielded the best time consistently.

The best way to use it is to go really fast.
You can't be that picky considering the longer
you save it, the less other items you can acquire.
Also, saving items tends to become frustrating when an attack causes you to lose them, might as well have used it when you had the chance and move to the next item quickly!

When you get an golden mushroom (the orange one) in Mario Kart 64, should you repeatedly press the Z button as quickly as possible, or should you delay it a bit in order to maximize the boost you get from the mushroom?
What's the most efficient usage of the golden mushroom in Mario Kart 64?

It doesn't matter how long you leave it. Pressing it as fast as you can might give you the last boost. It does not really matter how it is used, however after 4 usages it may give the player some extra distance. If you are able to give the boost just under a second and a half, this yields the best results.
This user states that it does not really matter how it is used, however after 4 usages it may give the player some extra distance. This user has tested the issue and presents the fact that giving the boost just under a second and a half, yields the best results.
