Useful Tips To Improve The Performance Of Your Blog

Blogging is an interesting venture for anyone that would like to share content or an opinion on a particular subject. Others like to blog about their daily struggle, or ask for encouragement to get over an addiction, and so on. Read this article to learn how to run a blog, no matter what you write about.

Ensure that the titles of your blog posts are very catchy. Imagine that you are someone who is just browsing the internet and you see your blog post among thousands of others. You should ensure that your blog headline sticks out from the rest.

Since blogs are written on a more personal level, you should avoid writing in formal tones. This will make it easier for the reader to relate to you on a personal level. This will keep your readers coming back later on to read more of the blogs you write.

Everyone makes mistakes, it is only natural. It is helpful to use Google Webmaster Tools when checking your work to point out any mistakes that you might have made. All you will need to do then is go and fix them, and nobody will ever see anything that you have messed up on.

If you want to be a good writer, it is important that you are a good reader. Take the time to actually read what you write about, and enjoy it. When you can read it from a visitor’s point of view, you will be able to get a better understanding of any changes that you need to make to your writing style.

The content on your blog will define it, so make sure that any audience you hope to draw in is entertained. Posting unique content that includes pictures or videos is a good way to add variety. Remember the tips in this article if you’d like to learn how to run a blog.

High Performance Web Applications - Part  1

High Performance Web Applications – Part 1

High Performance Web Applications – Part 1

Today most developers look at the performance considerations after launching the application in Production which is primary reason failures of lot of applications. Performance requirements should be considered from the initial design all the way to production launch. This series is going to describe how high performance can be achieved on the client side (Browsers), Server Side (App Server) and on the DB.

This first part will give some basic tips on improving client side tuning:

1. Reduce the round trips to the server by combining multiple JS files into one JS file.

2. Reduce the round trips to the server by combining the multiple CSS files to single CSS file.

3. Set Expires header attribute on everything you can into future based on your needs. This tells the browser it is okay to not revalidate on every request, which can add latency of at least one round-trip per object per page load for no reason. Particularly ensure directory where images are stored has Expires Header attributes set to enable the Browser caching. Just by reducing the 304 status calls to your web server would minimize the load on the web server and improves the page response time.

4. Externalize the JS code to separate JS file and include it and ensure JS files directory on the web server has caching turned on. You need to change the name of file if you make any changes else browser won’t download the latest JS files.

5. Make use of CSS attributes instead of using STYLE attribute in the individual HTML elements. Browsers renders pages faster with CSS class attributes than STYLE attributes.

6. Minimize the HTTP response size by enabling GZIP or any compression on the web server. Most modern supports GZIP compression and this reduces the page load time dramatically.

7. You can also improve the response time by adding parallelism to your content. Most browsers limits two concurrent connections to the single host by creating CNAMEs to the same domain you can make use of todays high bandwidth and reduce the response time. Its not advised to have more than 4 aliases to the same domain name. Having more than four aliases/CNAMEs create undesired effects.

8. Minimize the number of domains referenced in the web page. Each host name adds the overhead of an extra DNS entry lookup and an extra TCP three-way handshake. So too many domains referenced in the same page may cause an unexpected delay in the response time.

9. Minimize HTTP request size. Often cookies are set domain-wide, which means they are also unnecessarily sent by the browser with every image request from within that domain.

By implementing the above tips mentioned which doesn’t involve any code changes and just by making these environmental related changes you can improve the response time of your pages dramatically and enhance the user’s perception about your site.

Today’s AJAX based web applications has become quite common and in the next part we will discuss about tips to improve the performance of your JavaScript code.
