Eliminating System Bottlenecks

BURBANK, CA--(Marketwire - January 20, 2011) - Bottlenecks are no fun in any situation. Ask anyone who has to drive through rush hour traffic in the morning -- a freeway bottleneck is where you sit in your car, unmoving, fretting over being late to work. If you get caught up in a security bottleneck in an airport, you're dashing frantic looks at the clock, worried that you're going to miss your flight. There are many more such examples, all equally infuriating.

Bottlenecks also occur in computer systems, and can be a major source of frustration for IT personnel. Technically, a bottleneck is a delay in transmission of data through the circuits of a computer's processor or over a network.

In processors, the delay typically occurs when a system's bandwidth cannot support the amount of information being relayed at the speed it is being processed. If all of the components of a system are not able to feed the same amount of data at the same speed, a delay is created. For example, a 2GB processor will be severely bottlenecked by an 800MB memory bandwidth.

In the network situation, the flow of information transmitted across a network is slowed down. Network connections were originally designed to transmit only text files, and the proliferation of bandwidth-intensive transmissions such as high-resolution graphics has caused bottlenecks in the process. These can also be caused by file system bottlenecks, as will be seen below.

One basic factor that can cause bottlenecks is often overlooked, and should always be addressed first: that of the reading and writing of files. If files are not properly organized on a drive, they are written and read in many pieces -- which can jam up memory, processors and networks as well. It takes longer to read the file from the drive into the memory, then from the memory into the processor. The processor then must wait for all the data to be assembled, and is itself slowed down.

Networks become jammed because these many file segments are having to be transmitted individually.

Bottlenecks cause system slows, downtime and increased energy consumption -- and without addressing bottlenecks such issues will not be avoided. Additionally, bottlenecks will cause tremendous expenditure in IT hours chasing them down, many times futilely if the actual cause is not tackled.

The right choice to be made by IT staff is to address the reading and writing of files right at the beginning, using performance technology designed to do so. There is even technology available today that prevents a majority of them before they even occur.

Before wasting time attempting to solve performance and network efficiency issues, make sure to address file system bottlenecks completely in the beginning.
