The main idea of this project is to carry out performance analysis on the RDataFrame class within the ROOT operational framework. For this purpose, scalability analysis are performed on the execution of the Dimuon and Higgs tutorials evaluating concretely how the source code of these tutorials scales with different number of execution threads. Among others, it analyzes the comparison between compiled code and JIT (Just-In-Time), different types of storage (NVMe, SSD, EOS), memory usage and even measures the impact that NUMA effects have on performance.
