Measuring Performance

and and and and and and the how fewer I have nothing to fear area and and today we talked about of measuring performance with the use of an API which you want to crawl which like that that works in this ball those for other browsers do that in other places if you will this is more like a quick

story about my tinkering experimentation in and out of a lot about the thing that pixel how would outcome in and out so you you can actually see the Justice what I lecture today already posted over there some ecologists Jan through some information i've already shared or local media so my

curiosity about performance can is combined with the conviction that performance matters like such a major things and possibly take some observations and make decisions about what I'm majoring I am not very scientific about it yeah and I've learned that get better so this is also kind of a demonstration of you know learning from yourself and how you can improve in answer must support from the people there are staying with us are there in the house but I want to compare you know had a

Moslem . 3 in Additional lots and see if there was any genes in the application that like to tinker with my evenings and weekends in case you missed it now we have additional marginal I think you guys to the force really free from the fear of bacteria and things like

that of so we actually get a major on the performance metrics for rendering a template and so then talking about members primitives and we have a router that has this great hope for rendering the template and apparently everything's done and ready to go in this work so right there I can just mark the time majoring in down but what about after like when is it done so it has been done at some point all and you can it tells me is that enter the after rendered you that's that's done so I can just capture that major men tend no at that timing should be useful but the so this is a time stamp was a something better enough I started

searching and account user time EPI which has like high resolution timing in multi source of millisecond resolution of like that's probably faster than I can think like that school that

but so where I realize that I was capturing the things that I could just send them to Google Analytics and they can do nice reporting in charts for me so I'm going to send some of that data there is was captured my own

database of so I clinics and and show you a quick sense really

easy now you may want to try it but it's super simple right to mark the beginning and the end in there's 2 points when enter this this vote and then after when you tonight is to capture this measurement so I also have a utility on

of a certain distance and reports on 1 of its too slow on so

this is utilities right like does when the performance exist so I can fail silently if it doesn't exist at that does I can use that API to to mark a major so you learn more about that despite beginning in research in a library has some links were Russia with you after and then I wanted to reported numbers can like postage my API send measurements that use on documents also send it to Google Analytics for tracking purposes on the gamma

controls could now because it's available on my website in again you'll find the links for you know these performance appears as well some

great tutorials from what each of 5 rocks and that's kind of where I started as well as I have a few accidents few that sound very analytical like whenever he she was ready in image of useful

sometimes I dig into these metrics of more but this is just the just the kind of what I'm capturing what was important for me was this duration values and that there is something that I can compare so what

we might ask how would I find it on

honestly I can't really tell you because all they

did was observed the findings in on the I didn't really

study on proper benchmarks so results and helped me realize that history is all sort into about it this is probably a better way to like

come up and summarizes data by using

you know normalize data and actually a geometric mean of was kind of look at like what was

fast in what was slow and can show me some

averages and you that might help me a little bit deeper on somebody

that X right on the phenomena just like jam through a couple quick measurements is the highly

like his Lysol on In not

even talk about him because like I said at this point they're just observations and not

necessary conclusions but in a way like now I

have something in my and that matters to my users that I

can at least observed and on at

some point do something about so the command

time the vise OK but there's more of a lot so you can reverse the initiation and will the the
