a bottleneck occurs when there is some restrictive element holding back the
performance that could otherwise be achieved the name comes from the way
that fluid flows much slower through the neck of a bottle than it would if that
neck didn't exist another word for a bottleneck is a chokepoint let's start
with a couple of examples in a vehicle the traction between the tires and the
road is important for optimal power delivery between the engine and the road
making the car move forward now an example of where traction would be a
bottleneck would be if your engine is so powerful that when you go to accelerate
the wheels just spin now at high speeds a wing can improve traction by using
airflow to force the rear of the car down towards the road this can alleviate
that bottleneck well hey that sounds great why don't we just all get wings
and put them on our cars no that's not the answer this civic's performance for
example was not limited by rear wheel traction and it probably doesn't even
have sufficient power for the benefit of the downward force to outweigh the
negative effects of the additional wind resistance caused by this upgrade so in
this case it wasn't a bottleneck at all so changing it doesn't help and actually
might even make things worse so this is a tech channel so our next example is a
pc one let's say you take a very old computer and assuming it's even
compatible you put the very latest thousand dollar graphics card in it the
pc is not going to slow down and honestly gaming performance will
probably be improved but that card won't reach its potential even though the new
card might be 10 times faster than the old one you may only get a small
performance increase because the CPU and memory and potentially other components
are so slow that they can't feed the graphics card data at a fast enough rate
to keep it busy so it's just sitting there most of the time in that example
of bottlenecking those funds could have been put to better use on a more modest
all-around system upgrade which would have achieved better performance in
gaming and in other applications at the same time now with all that out of the
way it's important to clarify this whether we're talking about your pc car
air conditioner phone or even your very own body everything has bottlenecks you
can't just hide from them until the point where a task can be performed
perfectly and instantly something is always holding back or bottlenecking the
process so if they exist everywhere what can we do about them the answer is to
reduce them avoid extreme bottlenecks figure out what you're trying to achieve
and direct your resources towards the things that directly affect the
performance of the things that you care about so back to pcs as an example if
you're a gamer spending a big chunk of your budget on a graphics card does make
sense as long as the rest of your components are reasonably up to snuff if
you're not sure how to balance your configuration check out the linustechtips.com forum for fast
