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 with Three different thread sizes and Small Number of Files

• Number of Threads = 1
