00:00:00.160 --> 00:00:05.759
a bottleneck occurs when there is some restrictive element holding back the

00:00:04.240 --> 00:00:10.320
performance that could otherwise be achieved the name comes from the way

00:00:08.160 --> 00:00:14.240
that fluid flows much slower through the neck of a bottle than it would if that

00:00:11.920 --> 00:00:19.199
neck didn't exist another word for a bottleneck is a chokepoint let's start

00:00:17.199 --> 00:00:23.199
with a couple of examples in a vehicle the traction between the tires and the

00:00:20.880 --> 00:00:27.199
road is important for optimal power delivery between the engine and the road

00:00:25.359 --> 00:00:31.039
making the car move forward now an example of where traction would be a

00:00:29.039 --> 00:00:35.840
bottleneck would be if your engine is so powerful that when you go to accelerate

00:00:33.120 --> 00:00:40.239
the wheels just spin now at high speeds a wing can improve traction by using

00:00:38.399 --> 00:00:44.239
airflow to force the rear of the car down towards the road this can alleviate

00:00:42.399 --> 00:00:48.320
that bottleneck well hey that sounds great why don't we just all get wings

00:00:46.239 --> 00:00:52.640
and put them on our cars no that's not the answer this civic's performance for

00:00:50.480 --> 00:00:57.199
example was not limited by rear wheel traction and it probably doesn't even

00:00:55.280 --> 00:01:00.559
have sufficient power for the benefit of the downward force to outweigh the

00:00:58.800 --> 00:01:04.960
negative effects of the additional wind resistance caused by this upgrade so in

00:01:02.640 --> 00:01:08.640
this case it wasn't a bottleneck at all so changing it doesn't help and actually

00:01:06.880 --> 00:01:12.240
might even make things worse so this is a tech channel so our next example is a

00:01:10.320 --> 00:01:16.000
pc one let's say you take a very old computer and assuming it's even

00:01:14.080 --> 00:01:19.920
compatible you put the very latest thousand dollar graphics card in it the

00:01:18.080 --> 00:01:24.400
pc is not going to slow down and honestly gaming performance will

00:01:21.520 --> 00:01:28.960
probably be improved but that card won't reach its potential even though the new

00:01:26.960 --> 00:01:33.680
card might be 10 times faster than the old one you may only get a small

00:01:31.200 --> 00:01:37.920
performance increase because the CPU and memory and potentially other components

00:01:35.600 --> 00:01:42.000
are so slow that they can't feed the graphics card data at a fast enough rate

00:01:40.320 --> 00:01:46.159
to keep it busy so it's just sitting there most of the time in that example

00:01:44.000 --> 00:01:50.560
of bottlenecking those funds could have been put to better use on a more modest

00:01:48.320 --> 00:01:54.079
all-around system upgrade which would have achieved better performance in

00:01:52.079 --> 00:01:58.159
gaming and in other applications at the same time now with all that out of the

00:01:56.240 --> 00:02:02.560
way it's important to clarify this whether we're talking about your pc car

00:02:00.399 --> 00:02:08.479
air conditioner phone or even your very own body everything has bottlenecks you

00:02:06.079 --> 00:02:13.680
can't just hide from them until the point where a task can be performed

00:02:10.800 --> 00:02:18.319
perfectly and instantly something is always holding back or bottlenecking the

00:02:15.599 --> 00:02:24.000
process so if they exist everywhere what can we do about them the answer is to

00:02:21.040 --> 00:02:27.360
reduce them avoid extreme bottlenecks figure out what you're trying to achieve

00:02:25.680 --> 00:02:31.280
and direct your resources towards the things that directly affect the

00:02:29.520 --> 00:02:35.680
performance of the things that you care about so back to pcs as an example if

00:02:33.599 --> 00:02:39.360
you're a gamer spending a big chunk of your budget on a graphics card does make

00:02:37.680 --> 00:02:42.959
sense as long as the rest of your components are reasonably up to snuff if

00:02:41.840 --> 00:02:48.319

this as fast as possible episode like the video if you liked it dislike it if

00:03:29.120 --> 00:03:35.200
you disliked it leave a comment if you love bottlenecks or if you hate

00:03:33.280 --> 00:03:38.720
bottlenecks or have anything else to say about bottlenecks and as always guys
