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.
Do and Don’ts of the Interview Process No one likes job interviews. From the moment you schedule the interview you are under a microscope. Your potential employers waiting for you to make the move that make you stand out or eliminates you from being a candidate for the job. This necessary dance that just about everyone, has to go through can be mastered. Learn the key things to do to become a high-ranking candidate for a job. First of all, before you go to the interview be prepared. Having copies of your resume and pens are only half the battle. Where exactly is the office located? Do not leave the location or the interview site up to chance. The only way to know exactly where your interview is and how much travel time you should allow is to go there. Even if you are interviewing out of town, find out how long the drive is to the interview. Nothing disqualifies you, in most cases, faster than being late for your interview. Before you are sitting across from the interviewer, accumulate some knowledge about the company. Knowing about the position is not enough. Everyone that interviews will have read the advertisement for the position. You need to be armed with information about the company. Have they won any service awards? Are they ranked as one of the best companies in America to work for? Find out and impress the interviewer. Another way to impress the interviewer is to have intelligent, thoughtful questions to ask. Ask about productivity, benefits or training procedures. Show that you have done your homework and are truly extend about the position. Be attentive and bring the interviewer as much information as possible about yourself. If you have a portfolio or reference letters, be sure you take them to the interview. Also be prepared with complete work history and information as well as past residency information. Be ready to answer a few probing questions. Why do you want the job you have applied for? What makes this a good time for a job or career change? Have some intelligent answers for these questions. Interviews will know if you are nervous. No matter how badly you need the job, do not appear desperate. Show that you believe in yourself and are confident about your ability to do the job. Speak in terms of when you get the job opposed to it. While this is a bold move it is a way to reinforce the idea of you being chosen for the job. This is a trick for both you and the interviewer. No matter how true this may be, never tell the interviewer that you “really need a job”. If this is what you tell the interviewer they will think that you are willing to take any job. Also, never talk negatively about your current boss or co-workers. Give as objective view as possible if you are asked about your current job relationship. Inquire about the next interviewing steps. This will not only show the interviewer that you are interested in the position it will also give you some time to prepare if you are called for the next interviewing step. Be sure to keep a notebook in your car so you can jot down notes immediately after you leave the interview. This is the best way to keep track of important facts about the position. In a day or so, mail a thank you card to your interviewer. This could be the added interest they are waiting to see from you in order to eliminate the other candidates. Why Taking that Vacation Can Lead to a Better Workplace Do you love your vacations? Are they relaxing, fun and entertaining? There are many reasons why a vacation can enrich your life and fulfill you with joy and happiness. But many of these reasons actually can also be directly translated into reasons for why taking that vacation can lead to a better workplace for you, your boss and other employees. Vacations are as essential to a hard working employee as a parachute to a person jumping from an airplane with the goal to land safely. Many employers would love to minimize the time you are gone from your workplace because they think the more time you spend there, the more work you will accomplish. This argument is right up to a certain amount of hours and days a months or a year, but whenever your body starts to get tired and exhausted, the amount of work that you produce decreases. The quality of your work starts to decline as well. Time off work, time together with your family, time to relax, time to regenerate and time to just plain have fun are very important in an employees life. Taking a vacation has many benefits to the employee, but also to the company you work for. The more relaxed and happy your worker starts a workday or the workweek; the better will most likely be his or her performances at work. Research has shown that relaxation and regeneration are essential to human bodies. Did you know that in some companies in Europe and Asia, the emphasis on relaxation goes so far that meditation, morning sport and a short power nap belong to their required parts of a work day? The United States is actually one of the only industrialized countries that does not mandate a minimum of vacation days that the worker has to take off. In fact, in many countries in Europe, a minimum of 20 and more days is the norm. Since the late 1970s, the average middle income family works in total hours three and more months a year more then they did back then and according to a research done by Boston College, approximately 25% of Americans do not take a vacation at all. After all these facts are slowly emerging from mounts of collected date, some of the bigger American companies have actually begun to realize that off-time and vacation are essential to prevent mishaps and screwed up designs and products. If you are not taking your vacation or your employers does not allow for any vacation, a series of health hazards such as stress and high stress, sleeplessness, burnout, heart attacks and even more serious health conditions can occur. Another big factor in working too much, working overtime or never having vacation can be problems and loss of family and friends. Problems with families and friends will directly impact performance at work and even though the employee might not talk about it at work or might b e holding back his or her feelings, the mood and general behavior of the employee will have an impact ion his work and other employees. Every employee should value the vacation time given to him or her and employers should grant the time asked for to their employees. Vacation is essential to the performance at work and the quality in products the company can deliver. Following the examples that are set by many European countries, the US should give their employees the time they need and also make sure that their employees do take the time off to be a better employee overall. Vacation is fun, relaxing and regenerating. |
