The speed of your website with my ideas

Speed kills. For usability and lack of speed kills. Many have mistakenly assumed the advent of high-speed connections to Internet sites would optimize performance irrelevant. On the contrary, it seems as Internet connection speeds increase, users simply become more impatient and demand for faster browsing. Then I met a few simple (and advanced) ways to speed up your site.

Before making any changes, I would recommend benchmarking your download time with the optimization of websites optimization tool web pages.

Picture Enhancement Tips:

Compress images jpg gif and.: If using Photoshop, always use the "Save for Web". If you do not have access to the PS, there are plenty of free image compression software is free.
Compress or delete unnecessary elements Flash: In my opinion, Flash is a type slower, and buggy. It has its benefits, but be sure not to rely on it for navigation or other elements of the site required.
No Resize HTML image: Do not use the width or height attribute in the IMG tag to change the larger size options. For example, if you resize an image that was originally 300 x 300 100 x 100, the user has to download the full size one. In contrast, the use of miniatures.
Specify the dimensions of the image: Do not let the attributes of width or height blank. In this way, you stop the browser version of the page, it does not know the amount space to give each image.
Cut pictures: Cut does not actually reduce the image size (in fact, increase the size total). However, it does increase the apparent load time of each slice are doing one at a time instead of one large image to appear after it is downloaded.

Avoid too many slices: Do not use too much of a good thing. As mentioned above, each slice actually increases the total size. I recommend using no more than 4 slices, unless it is a great image.

Coding Tips

Use CSS instead of images: sheets Cascading style can do more than you think. Many sites make effective use of CSS format, eliminating the need for excess images. Even the brand logos Effective CSS.CSS can create with Zen Garden are some examples of creative use of CSS. Convert table based CSS design: tables are good for displaying data in columns and rows, but it is inefficient to design web page layouts. By using DIV tags with CSS, you can clean your code extensively, which will reduce time page load and also provide SEO benefits. Use external style sheets, rather than format using inline styles embedded in the pages or html elements, reference an external CSS file that everyone can reference site. The browser cache of this page in the first visit, so you will not have download on several occasions. External use [removed] simliar above, put all your JavaScript functions in an external file for caching benefits. Remove spaces unnecessary blank HTML: Surprisingly, the space hogs lots of disk space. Remove unnecessary space and clutter of other code with this handy tool called HTML Tidy. Use shorthand CSS: Instead of putting each CSS attribute on its own line, use CSS shorthand to avoid extra line breaks in external CSS file. Use CSS instead of images of the IMG tag: An easy way to speed up the rendering of an image is to simply call in the background of a div tag. Use links related: Removing http://www.yoursite.com "" From the beginning of each link will shed some weight. Be careful not to let people come and go between secure and insecure pages, which will generate one of those annoying "unsafe. items" errors in the browser Specify the type of document: Pages that have the specified document type tend to load faster than those who do not.

Server and database Tips

Reduce HTTP requests from other places: Try to delete the connection to other servers to retrive images, audio or video. Each connection http:// only slows things down. Do not use https: /: Do not use secure pages if you do not have to. Connection via secure http is about 3 times slower that regular http. Obviously, the payment process should be safe, but their product pages most likely do not. Also, make sure that your navigation does not use relative links, which forces users to flip flop between security and non-secure pages. Update your Web server: As the old PC he bought 5 years ago Web servers can go downhill and become obsolete. Use Gzip compression to reduce the size of HTML: Gzip is great to compress HTML code, however, does nothing for the images, flash or other embedded files. Many open source software like Joomla and WordPress support it. Memory Expansion Server: Increased memory resources on the server can reduce processing time and significantly increase performance. Update your hard disk database server Data: The faster hard drive of your server can access data, the faster you can serve files. A fast hard drive is especially important for server database. Separate content servers and databases: If you have a high traffic web site, databases, you can benefit by placing their content on a server and database on another. Besides the benefits of speed, which is safer.

Other tips

Load Indicators of progress: By letting users know that you are processing your request, you can alleviate your fears impatient. This is not necessarily to speed things up, but will update on progress. Using AJAX instead of updating the page: the interaction with a website is very different from interact with the computer operating system. Imagine if Windows XP had the time to update the screen every time you perform an action, such as websites do? In the coming years will likely see greater adoption of AJAX technology, which will uncessary page refreshing. Reduce the size and number of cookies: Every time a browser makes a request, cookies must be transmitted. Keep an eye on the total number and size of your site uses cookies.
