This page contains the software and data presented in the following paper:

  • "Benchmarking Personal Cloud Storage" by Idilio Drago, Enrico Bocchi, Marco Mellia, Herman Slatman and Aiko Pras. In Proceedings of the 13th ACM Internet Measurement Conference. IMC 2013.

This paper is a continuation of our work on personal cloud storage. Previous results can be found on this page and on this page.

The slides of the presentation can be downloaded from here.

Benchmarks Scripts

The scripts are written in python. All scripts require: netifaces, pcapy

How to execute the benchmarks

 sudo ./delta_encoding.py -i wlan0 --seed 123134 --bytes 10000 --test 3 -o /tmp/output/ --ftp 1.1.1.1 --port 2121 --user "user_name" --passwd "password" --folder="."

Important remarks:

1 - The folder ftp://user:pass@server/folder/ must be in a synchronized folder of the storage tool.

2 - The file delta_encoding.py must not be in a synchronized folder, otherwise the .pyc files created at run-time will disturb the experiment.

3 - The folder /tmp/output/ must not be in a synchronized folder, for the same reasons as above.

4 - Disable as much processes as possible in the benchmarking machine. This will minimize external interference on the test.

5 - If the storage system is running on a virtual machine, make sure the host machine is powerful enough to support the load. Check also whether the virtual machine limit or shape the network traffic.

6 - Post-processing scripts will be made available soon.

Traces

The traffic traces that generated the results in the paper will be made available soon.

Paper abstract

Personal cloud storage services are data-intensive applications already producing a significant share of Internet traffic. Several solutions offered by different companies attract more and more people. However, little is known about each service capabilities, architecture and - most of all - performance implications of design choices. This paper presents a methodology to study cloud storage services. We apply our methodology to compare 5 popular offers, revealing different system architectures and capabilities. The implications on performance of different designs are assessed executing a series of benchmarks. Our results show no clear winner, with all services suffering from some limitations or having potential for improvement. In some scenarios, the upload of the same file set can take seven times more, wasting twice as much capacity. Our methodology and results are useful thus as both benchmark and guideline for system design.
