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.
Pertinent Advice for Negotiating Salary Your salary is a huge factor when it comes to job satisfaction and overall quality of life. That is why negotiating salary is something that you should never overlook. While many employers like to state that starting salary as if it were etched in stone, there is usually some leeway in how much you will make. Remember, what you make is going to affect your entire life. Negotiating your salary is something that you should take very seriously. There are a few things to consider before you start throwing out figures. You don’t want to lose the job you have just gotten. First of all, leave the salary negotiating for the end of the hiring process. This is important because if you agree to a lower salary earlier on in the hiring process, you will be locked into that salary. Also, as the hiring process goes on and you become more of an employee, opposed to an interview, your worth increases. If you have gone through several interviews and met a few different managers, you have been able to make an impression on a number of people. That means that several different people have measured your worth to the company. When salary negotiating comes around, you can ask for more money. With several different people discussing your salary there is a chance that your state price may win out. Before you begin negotiating salary, you should know how much you are worth. One of the most important aspects of job hunting is finding out how much your skills and talents are worth in the job market. Armed with this knowledge, you will be able to market yourself better and know whether or not the employer is bluffing you. If you know that the salary they are offering you is much less than other companies offering the same position are offering, start the negotiating. Employers are always looking for a bargain. They never shoot out the high end of salary numbers. Employers start out at the bottom of the salary barrel. That means you can work to boost the salary offer. Of course, you do not want to sabotage yourself by acting too cocky but do not crumble under pressure. Be savvy in your negotiating and recognize that if the company is hiring, they need you. Yes, you may need a job, but the need is mutual. They would not be going through the interview process if there were no need of your services. Also, they obviously were impressed with your credentials. Be sure that they appreciate you will a decent salary. Know when to start salary negotiation. When the employer is explaining the job description to you, if they state a salary that is lower than you would like, let that pass. Until you have been offered the position, you do not need to worry about the salary. The first thing is to get the job. Once the offer is made and you are filling out paper work, you can start the negotiating part of the deal. It is important to know when salary negotiating is not an option. There are certain jobs that offer a set salary for certain position. If you are interviewing for a job that has a stated, set salary, you do not want to negotiate. The stated salary is the one that you will be getting if you take the job. In these cases, whether or not you are willing to settle for less is the question at hand. If the salary is too low for you to handle, get out there and find an employer that appreciates your talents.
