> 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.
