Cloud Spectator’s Cloud Benchmark Analysis is based on our CloudSpecs Performance System, which automates open source performance tests to run 4 times a day, 365 days a week. At the beginning of every month, we update our list with the best cloud IaaS performer from the previous 30-day period. We congratulate all IaaS providers that make it on our list for their dedication in performance, but we do not endorse any these cloud providers. For more information, please contact us.
The central processing unit executes all commands to run applications. By computing mathematical sequences, the CPU is a core component in application functionality, and CPU-intensive applications include gaming, compression, encryption, and rendering applications.
To eliminate bottlenecks in performance, it is important for all components of the server to be optimized. Storing all of the data from your applications, the disk is important in loading applications as well as the operating system. Speed of reads and writes from the hard disk can also predict performance of servers, and are especially important for database functionality, which requires constant read/write commands.
Despite many bottlenecks in performance, one disregarded but extremely important performance bottleneck is in the internal network of cloud IaaS providers. For example, if the internal network bandwidth/latency is throttled and shared with many other users on the same cloud server, even the fastest SSD or flash disk technology inside a SAN would not perform optimally; the data simply cannot be transmitted to the CPU quickly enough for it to matter.
