Web Hosting - Bandwidth and Server Load, What's That?
Two key performance metrics will impact every web site owner sooner or later: bandwidth and server load.
Bandwidth is the amount of network capacity available, and the term actually covers two different aspects. 'Bandwidth' can mean the measure of network capacity for web traffic back and forth at a given time. Or, it sometimes is used to mean the amount that is allowed for some interval, such as one month. Both are important.
As files are transferred, emails sent and received, and web pages accessed, network bandwidth is being used. If you want to send water through a pipe, you have to have a pipe. Those pipes can vary in size and the amount of water going through them at any time can also vary.
Total monthly bandwidth is a cap that hosting companies place on sites in order to share fairly a limited resource. Companies monitor sites in order to keep one site from accidentally or deliberately consuming all the network capacity. Similar considerations apply to instantaneous bandwidth, though companies usually have such large network 'pipes' that it's much less common for heavy use by one user to be a problem.
Server load is a more generic concept.
It often refers, in more technical discussions, solely to CPU utilization. The CPU (central processing unit) is the component in a computer that processes instructions from programs, ordering memory to be used a certain way, moving files from one place to the next and more.
Every function you perform consumes some CPU and its role is so central (hence the name) that it has come to be used as a synonym for the computer itself. People point to their case and say 'That is the CPU'. But, the computer actually has memory, disk drive(s) and several other features required in order to do its job.
Server load refers, in more general circumstances, to the amount of use of each of those other components in total.
Disk drives can be busy fetching files which they do in pieces, which are then assembled in memory and presented on the monitor, all controlled by instructions managed by the CPU.
Memory capacity is limited. It's often the case that not all programs can use as much as they need at the same time. Special operating system routines control who gets how much, when and for how long, sharing the total 'pool' among competing processes.
So, how 'loaded' the server is at any given time or over time is a matter of how heavily used any one, or all, of these components are.
Why should you care?
Because every web site owner will want to understand why a server becomes slow or unresponsive, and be able to optimize their use of it.
When you share a server with other sites, which is extremely common, the traffic other sites receive creates load on the server that can affect your site. There's a limited amount you can do to influence that situation. But if you're aware of it, you can request the company move you to a less heavily loaded server. Or, if the other site (which you generally have no visibility to) is misbehaving, it's possible to get them moved or banned.
But when you have a dedicated server, you have much more control over load issues. You can optimize your own site's HTML pages and programs, tune a database and carry out other activities that maximize throughput. Your users will see that as quicker page accesses and a more enjoyable user experience.
Achieving a Better Family and Work Balance Makes for Better Job Performance Are you constantly working after hours and weekends at the office? Are beginning to forget what your family even looks like? Many people find themselves in this predicament. Work seems to get more and more demanding with every passing day, and to stay on top of your game at work, you feel like you need to put in long hours. The flipside to this is that of course when you are at the office, you are away from home ? away from family dinners, play time and your kids? sporting events or school plays. You may feel like your hands are tied ? that no matter how much you want to be more involved with your family life, you have to keep working as hard as ever to make sure your family is provided for in the long run. The truth is, however, that you may be doing yourself a disservice on both fronts. Studies have shown time and again that well rested workers with well balanced lives are more productive in the time they do spend working. In the end, the best way to be a stand out worker at the office is to be fully involved and present in your family live. But wait, you say, ?I?m working practically around the clock now, and everything still isn?t getting done.? However, maybe the problem isn?t that you aren?t working hard enough. Maybe the problem instead is that you aren?t working smart enough. Think about the way you spend you working day. Are you taking on more responsibility than you need to, instead of delegating tasks to others? Are you spending a lot of time chatting in the break room when you run for a cup of coffee? Are you procrastinating so that big projects require you to work all-nighters instead of spreading out the work? Keep a journal of all of your activities at work for a few days. You might be surprised to see how you are really spending your time and in what areas you could make improvements. Simply staying on task and delegating effectively could get you home in time for dinner. When you have done everything you can to make your work habits as productive as possible, it is time to turn to other ways to balance your work life and your family life. Rule number one is the hardest one for most people to follow you ? draw clear lines of distinction between work time and family time. Family time isn?t really family time if you are constantly on your cell phone making and receiving work calls or if you are on your laptop for the entire family vacation. When you?re working ? work. When you?re with your family ? concentrate on them. The time you spend actually taking a breather from work will recharge your batteries and make you a better worker when work time rolls around again. Next, you have to evaluate your priorities. Maybe working around the clock will help you make partner faster, but at what cost? Decide if seeing your daughter?s soccer game every week is more important to you than moving up the corporate ladder quickly, and make adjustments in your schedule appropriately. There is no right or wrong answer, but deciding where you priorities lie will make scheduling easier for you. With your priorities in mind, see what work options are available to you to help you meet them. If you want more time with the kids, see if your office offers flex time or part time hours to help you meet your family commitments. Last but not least, don?t feel guilty about taking time with your family. Not only is this time important to your family, you can rest assured that the time out from the office stress will make you more productive when you return to work. Editing for the Next Generation: The MySpace Form (myspace editing) The goal of a good editor is to make any piece of text appropriate for its audience and form. Books must fit into the expectations of a publishing company in order to fit the expectations of those who buy the books. Magazine articles must fit the style of the magazine including its goals and also its audience?s expectations. Content is certainly important, but voice and specific word choice are also big components of catering to an audience. A scientific magazine should not sound like the latest gossip. Likewise, a glamour magazine should be far from stiff and boring. When it comes to internet editing, even more elements are added to the typical editing criteria. Consider for a moment the different aspects of editing for the MySpace pages. Individual Pages An individual is not required to edit their pages. MySpace editing does often involve self-editing however. A page owner is writing about themselves, introducing themselves to many other people. No doubt that page owner wants to send the right message. Self-definition is very important in order to effectively communicate your intentions with others. That is where MySpace editing comes in. Here again, word choice is very important. Careful use of adjectives and other descriptive words can paint a picture for other visitors to the site. Using generic terms like ?thing? and ?a lot? will leave a person sounding boring and bland. In addition to self-representation, individual pages really should be edited for appropriate citations. That may sound tedious and so like ninth grade English class, but it is important. Quoting authors and lyricists on your page is an effective way to express your own feelings, but if the words are not your own, you cannot claim them. Plagiarism is wrong. In addition to the ethical issues, you should give credit to the people you quote for other reasons as well. Visitors to your page may really appreciate the words and lyrics that you quote. If you give credit to their author, other people can find more similar words to enjoy. Corporate Pages MySpace editing is useful for individuals, but it also opens up job opportunities. Because of the popularity of MySpace pages, advertisers have naturally started enjoying the benefits of the high traffic. The problem is that many advertisers may not be familiar with the format of MySpace nor the appropriate language to use to reach the audience that is surfing there. A qualified user can use their expertise to help corporations effectively use the pages in order to best reach the audience. A member of that audience can edit for the presentation of content so that it will be the most effective at getting the readers? attention. If you are one of these qualified users, MySpace editing could lead you to a successful career in all kinds of editing. Use your own page as a resume. If you aren?t interested in the career, you could just have some fun making the most of someone?s use of the pages. You will no doubt be well rewarded for your efforts. MySpace editing can take more than one form. The important thing to remember is that no matter what the format is for writing, correctness is important. Especially when your words are representing you, you will want to be clear and correct in your writing. Giving credit to those people you quote is the correct thing to do ethically, but it is also respectful. Finally, editing for companies without the proper know-how when it comes to internet advertising could be quite profitable. You?ll be more likely to get the job if your own page is effectively and correctly put together. |
