MDSS/BigRed Load Testing

I am working on a JMeter testing file to test the uploading and downloading capabilities of the file-manager portlet via connecting to MDSS (HPSS) and BigRed.


Important notes of the testing scheme:
- Each "user thread" within JMeter represents a unique portal user who will upload, transfer, and download a unique file
- To do more intense load testing, just add new users and new files for those users. Right now the test is set up to have a maximum of 3 users
- Sending the file from MDSS to BigRed requires knowing the "index" of the file. These all need to be hard-coded. For example, for my MDSS account, the first file is hard-coded to be at index 12 in the file-manager list, the second file is index 13, and the next at 14.. and so on. This is the case because whenever you upload a file to MDSS, it gets placed at the bottom of the list. My mdss account had 12 files originally (index starts from zero), so after the first upload, the newest file was given an index of 12 (remember index starts from zero).
