L-Store Upload Structured Testing

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
• Number of Files : 1500 (30 samples of 50 uploads)
