Description

Metacat listObjects performance is a little sluggish with 38072 documents loaded. The goals of this story are:

1.evaluate how this can be improved in Metacat. It seems likely that there is some room for improvement in the query being executed or perhaps the processing of the query.

  1. In retrospect, it would also be really useful to perform the simple test below to gather performance metrics with different numbers of documents loaded to provide a response time vs. document count response curve. Such a test should be performed on all member and coordinating node implementations.
