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.

There are some people who believe that they are meant to sing, or dance, or even write. Like all things, becoming a writer is a process and there are many hurdles and even steps, potential writers must take in their quest of making their writing dream come true. It has been said that the art of writing is exploration of you, your own thoughts, your own motivations, and your own goals. However, there is much more to being a writer that just learning to be a good writer. Potential writers must realize that a career writer is one that recognizes writing as a profession and craft that can be turned into a career. The first step to becoming a writer is the most obvious, which is writing. If one is going to make writing their career then they must write first. There are many who believe that writers have no excuse not to write. A writer who does not want to write may be classified as someone who doesn’t want to be a writer. However, there are many people who don’t have the time to write, and in some cases it is best for potential writers to get jobs that make use of their writing skills. Most writers believe that to become a writer you must work as a fiction writer, but there are many jobs that offer the experience needed to become a professional writer. Although the creative process may not be the same as writing fiction, by acquiring a job that uses their writing skills, potential writers will be able to write more creatively and efficiently as fiction writers. Nonfiction writing jobs include, journalism, becoming a technical writer, becoming a technical editing, science writing, marketing communications, sales writing, resume writing, freelancing, and many more. There are many writers who don’t believe that they have to write or obtain a job in writing to become a great writer, but writing is the key to becoming a writer. Another key step for potential writers is to use logic to create the vision, and to achieve the desired goal. Before writing, it is important to think about what you want to write, instead of thinking of what can be gain from writing. It is typical for many writers to site personal gain as their reason for writing, instead of financial gain. There are some who believe that you can’t put a price on pursuing a dream. Becoming a writer also requires working long, and odd hours. A creative idea may strike at any moment, and it is advisable for writers to write and to expand their ideas, no matter what time of day it may be. Potential professional writers should also become comfortable with their place as a writer, and comfortable with their own creative process. If you are going to write, it is best to find a process that works best for you, and to use that process in all of your endeavors as a writer. Writers who have a steady process and who strive to become better and to write more will eventually achieve the success they want. Potential writers should also know that writers’ block is not real, and many times writers cannot write, because they are lacking something and may need to fill a need in order to return to their comfortable place of writing. Becoming a writer is not easy and many writers may run away when they see all the hard work that is required. However, there are many who pursue their dreams and who become the writers they always wanted to be. So, while it may be easy to run away, it is always more rewarding to face a challenge and come out on the other end as the victor, and for many that means becoming a writer. |
