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.
Ten Top Things That Make for a Great Employee If there is one thing that everyone can agree upon in the job market it is that great employees are hard to come by. Whether you are an employee yourself and you feel like you are always pulling the weight of the other people in the office or if you are a boss who is wondering how you can actually get some people on board who can do the job, you know that great employees are at a premium. But what exactly makes an employee great? These ten top things are guides to bosses looking for greatness in a new hire and for employees trying to get noticed in the workplace and be the kind of employee who has the potential to move up in the company chain. The first thing that makes an employee great is that they are always dependable. Great employees do the job they are supposed to do every time, and no one has to worry that they don’t deliver the goods. A great employee can be counted to always have their work done right, when it is supposed to be done – it is a forgone conclusion that they will, and no one else has to spend any time worrying about it. The second thing to look for in a great employee is that they are a team player. A great employee isn’t one who is constantly looking for attention or hogs the spotlight. Instead, a great employee works with everyone else to make sure that the things that need to get done do get done, for the good of the company. The third mark of employee greatness is that they know how to take direction. Great employees know how to take criticism, direction and advice gracefully and make it work for them when doing their job. Fourthly, a great employee can be trusted. They don’t spread office gossip and they don’t dish company dirt. Likewise, they always tell the truth to their employer, even if it lands them in hot water. The fifth sign of greatness in employees is linked to the fourth – a great employee always guards the confidential nature of their business dealings and protects everyone’s privacy. The sixth thing that makes an employee great is that they participate in the day to day life of the office. They don’t bow out of meetings or skip the office birthday celebrations. These things may not be a fun part of working life, and everyone involved knows that everyone else has some place they would rather be – but a great employee wouldn’t be any place else. In seventh place comes the fact that a great employee gets along with other employees. Every office has one person that is in everyone else’s business and talks to loud on the phone and generally stirs things up and gets under everyone’s skin. This kind of employee zaps office morale – a great employee is a good co-worker to everyone. The eighth thing a great employee has is good working skills. It may sound obvious, but a great employee has the abilities needed to do their job, and they constantly seek ways to improve, like going to training seminars or seeking further education. Great workers have great skills. The ninth thing that leads to employee greatness is tact and decorum. If there is a problem in the office, a great employee doesn’t make a scene in front of everyone else. A great employee will deal with such issues with privacy and diplomacy. Further, a great employee doesn’t tell tasteless, political or religious jokes, nor do they send emails that tell these kinds of jokes. Last but not least, a great employee has a great attitude. Bad attitudes bring everyone down. A great employee helps make work great for everyone else by having a good spirit about their job. 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. |
