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.
Helpful Hints on Getting Better Respect in the Workplace Sometimes, an inhospitable work atmosphere can ruin the best job in the world. If you work in an office where people don’t respect each other and you feel undervalued and taken advantage of, then you are likely to give up and move on--no matter how much you love the work. When people work closely together, disagreements and problems are bound to arise from time to time. There are, however, ways you can get more respect in the workplace, so you don’t have to dread heading to the office every morning. As the old adage goes, you have to give respect to get respect. Are you doing everything you can to treat your co-workers with dignity and respect? Put another way, are you doing everything you can to avoid annoying everyone in the office? There are a lots of little ways you can make the day more pleasant for everyone, including showing up on time for work and for in-house meetings, not talking too loudly on the phone, keeping your personal cell phone ringtone on silent or vibrate, and cleaning up when you use the common break rooms and kitchen area. Things like spamming everyone in the office with incessant “funny” emails, sending political or religious emails (or challenging everyone on political or religious issues), or invading privacy by looking at someone else’s emails, phone messages, or mail are also not a good idea in the office setting. Then there are the big ones – you should never take credit for someone else’s work, talk behind people’s backs, lie, steal from other’s desks (even if it is just a post-it note or white-out), or have a general bad argumentative attitude. If you are doing anything of these things, trying to correct your own behavior is the first step to earning a little more respect in the workplace. What happens if you are doing everything you can and you still aren’t getting the respect you feel you deserve in the office? How you handle things may partly depend on who is showing you the disrespect. Are your subordinates treating you like you’re not the boss? In this case, having a little one on one conversation might do the trick. It doesn’t have to confrontational. You can simply point out that you are getting the impression that they may be having a little trouble with your leadership style and offer them a chance to raise any problems. If they bring up a legitimate problem, then there is something you can work on to make things go smoother in the future. If they can’t point to any one thing, let them know politely, but firmly, what you will need from them going forward in terms of respect. And then, stick to it and hold them accountable for their behavior. If your boss is not respecting you, things can get a little trickier. If your boss has a bad attitude, being pulled up on it by his subordinates is probably not going to do much to improve it. Your company may have a grievance policy in place to deal with issues like this, and it is best to go down this path when dealing with a boss with a respect issue. There are some respect issues in the work place that can’t be resolved with the softly, softly approach. If you are being persecuted on the basis of your gender, your race, your disability, or your sexual preference, you have a right to demand a stop to that at once. If the abuse is coming from your co-workers, go straight to your boss. If your boss is unresponsive, or if your boss is the offender, go right over their head, and keep going until you get some satisfaction.
