Test File Sets
Test design
Maximums to test for:
- Max number of SIPS - 10
- Max number of files in SIP - 10,000
- Max size of individual file - 30 GiB
- Max size of SIP - 100 GiB
Baseline amounts:
- number of SIPS - 1
- number of files in SIP - 10
- size of individual file - 1 MiB
- size of SIP - 100 MiB
| Test | No. of SIPs | No. of files in SIP | Max size of individual file | Max size of SIP |
|---|---|---|---|---|
| 1. Baseline Test | 1 | 10 | 1 MiB | 100 MiB |
| 2. No. of SIPs | 10 | 10 | 1 MiB | 100 MiB |
| 3. No. of files | 1 | 10,000 | 1 MiB | 100 MiB |
| 4. Max file size | 1 | 10 | 30 GiB | 100 MiB |
| 5. Max SIP size | 1 | 10 | 1 MiB | 100 GiB |

Old test findings
Findings when running a 2,000 and 10,000 object sip through (May 2011):
- the dashboard would lose contact with the MCP intermittently this maybe fixed with more cores in a processor
- transcoder extract packages was producing ALOT of log, causing the logs to rotate every few seconds. Is a less verbose log possible, with option for debug mode?
- Sanitize (/usr/lib/sanitizeNames.py) names hung For a very long time, MCPServer and MCPClient seemed fine however. My 2,000 object sip contained ~1,000 objects with spaces in the name, the 10,000 object sip contained ~9,000 objects with spaces in the name. On both the 2,000 object sip and the 10,000 object SIP the processing failed to complete.
