Objective

This is the first set of tests for Benchmarking L-Store system performance. We are setting up Upload testing to begin with.

Parameters

1. File Size: 

 * Small:  1KB file will be used
 * Medium: 0.5MB file will be used
 * Large:  260MB file will be used

2. Number of Files 

 * Small:  Essentially we will use the number of uploads set up as a surrogate for number of files. 50
 * Medium: 200
 * Large:  1000

3. Number of threads 

 * Small:  1
 * Medium: 20
 * Large:  60
  • Experimental Design: Full Factorial (3*3*3=27 test cases). Each test case would be run 30 times to collect statistically significant data.


Please watch this page as we post results from our runs.

Results for small uploads: 10 Threads

  • Number of Threads: 10
