Many companies are considering switching from SAS to R for statistical data analysis, and may be wondering how R compares in performance and data size scalability to the legacy SAS systems (base SAS and SAS/Stat) they are currently using. Performance and scalability for R is exactly what Revolution R Enterprise (RRE) was designed for. In a recent webinar, Thomas Dinsmore described a benchmarking process to compare performance of legacy SAS and RRE. (The benchmarking process is described in the white paper Revolution R Enterprise: Faster Than SAS, and you can see the code behind the benchmarking process here.) In the webinar, Thomas revealed the following results:
- RRE ran the tasks forty-two times faster than legacy SAS on the larger data set
- RRE outperformed legacy SAS on every task
- The RRE performance advantage ranged from 10X to 300X
- The RRE advantage increased when we tested on larger data sets
- SAS’ new HP PROC, where available, only marginally improved SAS performance
Also in the webinar, John Wallace, founder and CEO of DataSong, described how performance and scalability requirements led to the selection in 2011 of Revolution R Enterprise as the analytics engine in their software-as-a-service platform. DataSong's industry-leading marketing analytics system currently analyzes more than $3billion in marketing spend by major retailers.
