Message:

While working with large datasets in combination with pagination (ie. a pagination window of 100 or more), the performance drastically decreased.

I tracked the problem down to the setting of the parameters. In the old implementation, the parameters are set individually. This pull request sets the parameter as an array to the Query and Walker.

Testing results (# of entities, original performance, improved performance):
