[jira] Created: (OLIO-81) Cycle time distribution too small for
Add* operations
Cycle time distribution too small for Add* operations
-----------------------------------------------------
Key: OLIO-81
URL: https://issues.apache.org/jira/browse/OLIO-81
Project: Olio
Issue Type: Bug
Components: generic
Reporter: Shanti Subramanyam
Assignee: Shanti Subramanyam
Currently, the driver uses a neg. exp. distribution for cycle times with a 5 second mean and truncates the distribution at 25 seconds. For the Add operations, the response times can be quite high - this leads to much smaller think times which can cause the requirement for cycle times to fail.
We either need to increase the mean cycle time or truncate at a much larger value for these operations.
