hey people good morning you can do better than this good morning yeah that's what I'm talking about ah first of all it's my pleasure being here today and I'm talking about stress testing so I will walk around I spectrum bother anyone 1 billion
and sixth million of dollars one Dylan and six million of dollars that is what Amazon would expand with one page slow down one second page is low down in actually amazon is not the only one that are concerned about it there's a lot of other big companies
that would suffer and would spend a lot of money and lost a lot of money with performanc and PageSpeed other one is google google actually made this research that if they increase their page that they decrease their page speed by 500 milliseconds that would
drop their traffic by twenty percent twenty persons a lot and if we take a closer look at those numbers like the relation between payable demands increase and load speed we are going to see good stuff like the most important part about this graph here is the
four second data now only after four seconds so four seconds would increase your venom page rate by 25 person and it's a huge number it can make the difference between the Sosa's and the failure of a product it can make the surface between how many
peoples do you can support and how many lives you can change with our product and with your application and the thing is that the the users are not like really really freaking about speed and freaking about impatient is not about a generation thing actually
it's about neuroscience there's a fern research that was made with some users and the and the expectations are really high like 47 of the people that was considered tell that expected to a page load to be fully functional in two seconds and it's
too much and that this is not the worst part like the worst part is that seventy-five percent of the same people seventy-five percent of the same people said that they would not return if this page took more than four seconds to load and yeah you should be
worried about it because our brain does not operate kooten that doesn't parade really well in short-term response and in short term memory actually our short-term memory can hold like anything for more than 10 seconds after some seconds you can literally
say that you forgot your what is your short memory so you must be really worried about it you must be working about it you must you must be working about performanc and all this is related about performanc performanc is like doesn't matter you are developer
doesn't matter you to our team leader doesn't matter you are product owner or if you're just another stakeholder some time in the life of your product and the life of your application you you end up have to deal with some questions like your application
meet the no function requirements how your application behave and extremely circumstance like have a traffic so performance effects everyone opposed and everyone that works in web development in industry I am is your modem i'm the founder and CEO of gioco
jerko is a size gamification platform and i'm here to talk to you about stress testing as a culture the first thing that we have to ask ourselves here right now is how to increase the success rate of my application to meet the needs related to scale this
is the question here right now because the stress testing performance texting loads testing it's all related about scale is all related about being ready to handle extreme circumstance into your application and to talk about scale to talk about performance
and tasks I will go through four key points it's for simple key points that will enable you to start to stress testing and to address the stress testing as part of the culture of your application but in order to talk about those four key points I have
to tell you guys a story and to tell the story you have to tell you from where i am and i'm from brazil for those that doesn't know this is the Brazil's flag and this is exactly where I leave so I came all the way down to be with you and to share
with you this experience and everybody and everybody that that asks me when I tell them from Brazil and i have been in conference all around the world and every time that I tell them like I'm from Brazil everybody asks me about oh and what about the trees
the lake the florist and the animals and other school stuff that you guys have around and absolutely have a lot of trees lakes and forests but it's not usually in the whole country like I have never been one of those scenarios actually I came from some
pollo and this is Apollo pretty different actually I have some cool stuff to tell you about some pollo sao paulo is the largest city in that whole americas and it's a maze and not just the biggest the largest city it's actually the most popular city
in the whole so transfer it's really huge and actually we have a lot of buildings we have a lot of traffic this is a usual picture of our Friday night yeah you can you can easily get stuck in one of those if you're in some pollo on a Friday night so
yeah there is no trees there's no latex there is no animals there's no this kind of thing where I leave but there one thing that we are good and really good at and it's fun we in Brazil love to have fun with large party would love to play without
