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.
To-Do Lists an Important Part of Being a Better Employee What makes a good employee? Take a look at how the star employee in your office operates. Chances are that they don’t run around in a constant fog of stress and pressure. Good employees are usually calm and conscientious; they seem to always get the job done with a minimum of hair pulling and frantic rushing around. Is it just genes that these people have that allow them to work like this, or are some people just better at managing stress than others? The answer is probably not. If you take a closer look at the star employee in your office, you will are likely to see that they are so stress free and productive because they are good at managing their time. And chances are they manage that time with the help of a to-do list. The to-do list is an often-overlooked part of working life. While they are the kind of thing people expect housewives to carry around with them in their purse while they run errands, many people think they can do without them in the work place. This is a big mistake. Being productive at work is all about being able to carry out your tasks in a timely manner, and being productive at work is also about managing your stress. If you are too stressed out, your work will suffer for it. You will fall behind because you won’t be able to concentrate, and you will make mistakes you might not have made if you were able to take your time with your work. So, how can a to-do list help? To-do lists can do many things for you in your busy working life. For starters, to-do lists remove the problem of having that all important phone call or meetings slip your mind. When you have a to-do list, everything that needs to be accomplished is set out there for you, so there is no more explaining to your boss why you stood up your company’s most important client. With a to-do list, you can also see the bigger picture of everything that needs to be done, so you can plan your time wisely. Working on tasks one after another as they come up is not a smart way to accomplish things at the office. Some jobs are on a tight deadline, while other jobs can stand to wait a little while. When you set everything out for yourself in a to-do list, you will be able to prioritize your tasks in order of importance, so you get the crucial work out of the way first thing, and only move on to less important jobs when you have the time to devote to them. All of this organization will make your working life less stressful. Imagine a typical day without a to-do list. You come in to the office in the morning, you work through all of the email sitting in your inbox, you make a few phone calls, chat with some co-workers in the break room, answer a few more emails, and then bam! All of the sudden, you remember that the presentation your boss needs for the big meeting is due at 2 p.m., and you haven’t even started it. Now you resort to hair pulling and frantic working. Then, you give your boss the presentation over an hour late, and it is filled with mistakes and sloppy work. Now imagine the same day with a to-do list. You get the presentation out of the way first thing, and you have time to check it. Then you can move on to less important tasks without the dark cloud of stress hanging over you. To-do list writing is time well spent if you want to succeed at work. Steps on Reinventing yourself to Land a Better Job Having a decent job can greatly improve the quality of your life. You probably spend a fair amount of time at work. With that in mind, you do not want to be miserable when you are at work. If you want a better job, make yourself more attractive to employers. This task may be easier than you think. Start making some simple changes and watch the job offers begin to appear. The number one way to reinvent yourself in order to land a better job is to reform your attitude. Even if you are working at a nightmare of a job at the moment, you need to fight to stay positive. That negativity can be seen a mile away. You may not realize it but your face expression, posture and quality of work give off your frustration. This attitude is the first thing that has to go. Simple ways to change the way you feel about your current job include being on time and in uniform or proper dress code. These are two easy steps that will give you more pride about yourself. If you are out of dress code and late, you are not just making statement about the job. You are making a statement about yourself. Change these aspects of your working environment and you will be on your way to increasing positive energy. Take some classes. Whether you have a degree or not, brushing up on skills is always a good idea. No matter what your schedule is like, you can find time for a class or two. Use the Internet and take online classes if time is a major issue. Work at your own pace and pick up new skills. A degree or a couple of classes will make you more attractive to employers. Move away. If you are tired of dust collecting on your Communications degree while you wait tables, move to a place where your degree is more marketable. Find an area where the job market is fertile. When the economy goes south, certain job types are completely eliminated. If you are eager to find a better job you may have to go somewhere else to do it. Apply for higher positions in the company that you currently work for at the moment. Even if you are not really that thrilled about the current company you work for, while you are there you should make the best of it. Get as much experience as you can so that you will have a nice extensive work history to refer to when you are looking for a new job. If you want a better job, do some networking. Take advantage of the people that you know that have better jobs. Surround yourself with people that are working at jobs that they enjoy or are successful at. This is a great way to pave the way for yourself to get a better job. Figure out what type of job you want before you start looking. Narrow down the search and target the positions that fall in line with the jobs that you are most interested in. If you a constantly saying that you want a better job but don’t have any idea what the better job is, you are not going to be very successful in you search. Have a job in mind before you start your search. Join networking sites. These sites can be used for networking for jobs among other things. Be sure that you take the professional route when you put up your page. Let employers know that you are serious about finding a job. Do not post pictures of yourself at parties or in questionable positions. |
