Bottlenecks explain a situation where the state of a computing device and overloaded network are unable to keep up with the pace of the other system, which slows down the overall performance of the system. When many people hear about performance bottlenecks, some of the hot spots that come to their mind include network, memory, and CPU. You can begin by checking for bottlenecks at these places but remember that performance bottlenecks can hide in other places too. Bottlenecks can cause a functional server or computer to slow down to a crawl. For an organization to fix bottleneck issues, it first needs to identify the underperforming component then fix it so that the system returns to its required performance levels.

Memory utilization

Memory bottlenecks mean that the system lacks enough or fast RAM. It reduces the speed at, which the RAM serves information to the CPU resulting to slow operations. In situations where the system lacks enough memory, the computer begins to offload storage to a slower SSD or HDD to ensure that things are running. Also, if the RAM doesn’t serve data to the CPU as fast as is required, the device experiences both low CPU usage rates and slowdown. To resolve this bottleneck, you would have to install a faster or higher capacity RAM. Also, sometimes you would require RAM replacement or a professional to fix the bottleneck.

Disk usage

The slowest part of a server or computer is usually the long-term storage such as SSD and HDD. Disk usage bottleneck is one of the most difficult to troubleshoot because even the fastest long-lasting storage components are faced with physical speed limits. You can fix this bottleneck by enhancing data caching rates in RAM or reducing fragmentation problems. You can also switch to faster storage devices and increase RAID configurations when you want to solve the bottleneck on a physical level.

Software limitation

Some programs are designed to deal with only a finite number of tasks at a go; hence, they can’t utilize additional RAM or CPU assets even when available. Besides, programs can be written to work with a single core on multicore processors; therefore, they can’t work with several CPU streams. You can resolve the issue of software limitation by rewriting and patching software.

CPU utilization

CPU utilization bottleneck occurs when the CPU is overloaded so it cannot carry out tasks in a timely way. The bottleneck takes place when the processor is so busy such that it can’t respond to requests for time. CPU bottlenecks can manifest in two ways, which are an overly long processor queue and processors that run at a capacity of over 80 percent for a long time. The bottlenecks result from continual I/O devices interruptions and insufficient system memory. They can be solved by enhancing software coding efficiency, enhancing CPU power, and adding more RAM.

Network utilization

Network utilization arises when communication between two gadgets lacks processing power necessary to complete tasks quickly or the required bandwidth. They arise due to overburdened network communication or overloaded servers. You can fix the issue by adding or upgrading servers and network hardware such as hubs and routers.

For you to identify bottlenecks, you need reliable load testing and monitoring tools. The tools will also fix the issues as soon as they have been identified. It is also necessary to know where to search for bottlenecks because it is not rocket science.
