Performance Results
This document provides some data about the performance of different simulation scenarios in CloudSim and CloudSim Plus. Each row in the tables below is the results from a single simulation. This way, they aren’t scentifically valid and are only intended to provide a glimpse of how the latest versions of CloudSim Plus outperform CloudSim.
The results were generated using CloudSim Plus Automation tool in a computer powered by a dual-core 2.8 GHz Hyper-Threading Intel i7-4558U processor. Each results was generated from a simulation scenario defined in a YML file.
Cloudlet’s UtilizationModel
- Cloudlet’s UtilizationModel for CPU: UtilizationModelStochastic (1 instance for each Cloudlet, history enabled)
- Scenario File: CloudEnvironment6.yml
