Dedicated server hosting has one undeniable advantage: there’s a great choice of processors (CPU). How to compare them and find a suitable dedicated server?
The Central Processing Unit (CPU) in a hosting server (also called simply as the processor) is the device that executes and interprets commands, processes data and performs different functions like running databases, serving web pages, etc. The more processors in a server, the better its performance is, and the more instructions it can perform within some certain period of time.
The speed of a processor depends on the clock speed (how fast the processor performs instructions). Clock speed is measured in hertz (GHz), the higher it is – the more instructions will be performed by the CPU. However, clock speed is not the only factor defining the number of instructions in progress. Such things as the number of cores, multiple threading, subcycling, data throughput and latency also play great role.
Today, the vast majority of dedicated servers have multi-core processors which can perform many tasks being more efficient than older processors, even despite a lower clock speed. Although a 4-core processor is not always likely to be 4 times faster, it will still execute more instructions. Multithreading contributes to better performance by making server perform several processes simultaneously.
Another crucial aspect is the cache memory which boosts the speed of access to data stored on web server. With more cache memory, the processor will store more frequently required data which will improve performance of the processor.
Look through a broader lens
Note that the choice of dedicated server provider should depend not on web hosting server performance alone – service and other characteristics also matter. For instance, a dedicated server with a high processor clock speed should have a proportional bus clock speed so that you could get maximum performance out of this hardware configuration.
Besides, using simply the most powerful processor may be not a good idea, if your workload requires better disk performance of SSD, high level of RAM and redundancy.
Choosing a processor
The choice of processor performance, volume of RAM, size and type of storage and RAID should be defined by how you will use your web server and what the workload will be. If you need a free recommendation, contact our team, and we will figure out an appropriate solution for your online project.
