Regression Analysis for profiling L-Store metadata throughput handling

Objective
As part of some of the initial testing with L-Store these tests are attempting to create a base reference model for meta data handling with L-Store. Specifically we are interested in seeing that as we increase from very small file sizes to large file sizes whether the latency profile is a linear fit or a non-linear fit.
Parameters
1. File Size: 1KB, 500KB, 1MB, 50 MB, 100MB, 150MB, 200MB, 250MB
2. Number of Files: 30 files
3. Number of threads: 10 threads
Results
- Number of Threads: 10
- Block Size : 1MB (Each Slice is 1MB)
- Number of Files : 30
- Current Status: In progress
- Time of Completion:
| Type of Test | Number of files | Average File Size (MB) | Average Latency (sec) | Median Latency (sec) | Maximum Latency (sec) | Std Deviation on Latency |
