Разгони свой сайт

Методы клиентской оптимизации веб-страниц

Разгони свой сайт
  • Авторы: Мациевский Н.
  • Год: 2009
  • Язык: русский
  • Формат: pdf
  • Уровень: гуру
  • Сайт тормозит, и вы не представляете, как с этим справиться? Количество анимации на странице превысило все мыслимые и немыслимые границы, и вы не знаете, что делать? На странице десятки и сотни картинок, дизайнер превзошел сам себя, и теперь все это загружается страшно медленно? Эта книга поможет разобраться с этими и множеством других проблем, связанных с клиентской производительностью.

Вопрос скорости загрузки веб-страниц привлекает внимание всех веб-разработчиков уже очень давно — практически с того момента, как в HTML-документе появились картинки и веб-страницы вышли на уровень взаимодействия с пользователями, а не только предоставления им необ- ходимой информации.

За последние 10 лет уже многократно менялся сам подход к созда- нию сайтов. В эпоху браузерных войн и ограниченного доступа по моде- му наиболее важными аспектами клиентской производительности (отвечающей за скорость загрузки и работы веб-страницы) были ускорение пе- редачи данных и ускорение отображения этих данных при использовании многоуровневых таблиц на странице. О блочной верстке и семантической разметке тогда просто не думали.

Но ситуация изменилась. Сейчас средняя веб-страница уже крайне тяжело вписывается в установленные когда-то рамки «загрузка за 10 секунд на модеме». В среднем на ней используются десятки различных объектов, и не всегда это только картинки. Объем файлов скриптов, обеспечи- вающих взаимодействия пользователя с веб-страницей, сейчас уже намно- го превышает размер предоставляемой на этой странице информации. И мир движется в сторону усложнения взаимодействия человека с машиной, а никак не в обратную.

Данное издание старается объединить в себе все современные подходы к построению высокопроизводительных веб-приложений и просто веб-сайтов, которые быстро загружаются. Подавляющая часть материалов книги уже была опубликована в 2008 году на сайте Web Optimizator (http://webo.in/), из них были отобраны наиболее актуальные и проверенные на практике решения, которые и вошли в основу этой книги.

Кроме теоретических аспектов производительности приведено так- же большое количество практических рекомендаций, примеров конфигурационных файлов, различных приемов и проанализировано несколько высокопосещаемых ресурсов. Книга предназначена, с одной стороны, для последовательного погружения в сферу клиентской оптимизации веб-разработчиков любого уровня. С другой стороны, благодаря большому количеству прикладных советов, она ставит своей целью стать настольным справочником оптимизатора.

    Currently it appears like Expression Engine is the top blogging platform

    out there right now. (from what I've read) Is that what you are using on your blog?

    I've been surfing online more than three hours today, yet I never found any

    interesting article like yours. It's pretty worth enough for

    me. In my view, if all site owners and bloggers made good content as you did, the internet will

    be much more useful than ever before.

    I think what you posted was very logical.

    However, think about this, suppose you were to write a awesome headline?

    I am not saying your information is not solid.,

    but what if you added something that grabbed a person's attention? I mean Скачать книгу "Разгони

    to glance at Yahoo's front page and see how

    they write post headlines to grab viewers to open the links.

    You might add a video or a picture or two to grab readers interested about everything've written. In my opinion,

    it would make your website a little livelier.

    Howdy would you mind stating which blog platform you're using?

    I'm planning to start my own blog in the near future but I'm having a hard time deciding between BlogEngine/Wordpress/B2evolution and Drupal.

    The reason I ask is because your layout seems different then most blogs and

    I'm looking for something unique. P.S

    My apologies for getting off-topic but I had to ask!

    Howdy great website! Does running a blog such as this require a large

    amount of work? I have very little knowledge of programming however

    I was hoping to start my own blog soon. Anyway, if you have any ideas or techniques for

    new blog owners please share. I understand this is off topic but I simply needed to ask.

    Kudos!

    The words in your article seem to be running off the screen in Chrome.

    I'm not sure if this is a formatting issue or something to do with web browser

    compatibility but I thought I'd post to let you know.

    The layout look great though! Hope you get the issue fixed

    soon. Cheers

    Unquestionably believe that which you stated.

    Your favorite justification seemed to be on the internet

    the easiest thing to be aware of. I say to you, I definitely get irked

    while people think about worries that they just don't know about.

    You managed to hit the nail upon the top and also defined out the whole thing without having side

    effect , people can take a signal. Will likely be back to get more.

    Today, I went to the beachfront with my kids. I found a sea

    shell and gave it to my 4 year old daughter and said "You can hear the ocean if you put this to your ear." She put the shell to her ear and screamed.

    There was a hermit crab inside and it pinched her ear.

    She never wants to go back! LoL I know this is totally off topic but I had to tell someone!

    your website? Its very well written; I love what youve

    got to say. But maybe you could a little more in the way of content so people could connect with it better.

    Youve got an awful lot of text for only having one or 2 pictures.

    Maybe you could space it out better?
