The current max orphan transaction size causes problems with dependent transaction relay due to its artificially small size in relation to the max standard transaction size. Consequently, this modifies the orphan transaction policy by increasing the max size of each orphan to the same value allowed for standard non-orphan transactions and reducing the default max allowed number of orphans to 100. From a memory usage standpoint, the worst case max mem usage prior to this change was 5MB plus structure and tracking overhead (1000 max orphans * 5KB max each). With this, that is raised to 10MB (100 max orphans * 100KB max each) in the worst case. It is important to note that the values were originally implemented as a naive means to control the size of the orphan pool before several of the recent enhancements which more aggressively remove orphans from the orphan pool were added, so they needed to be evaluated again. For a very long time prior to recent changes, the orphan pool would quickly reach the max allowed worst-case usage and effectively stay there forever whereas with more recent changes, the actual run-time orphan pool usage is usually much smaller. Finally, as another point in favor of this change, as the network has evolved, nodes have generally become better about orphan management and as such missing ancestors will typically either be broadcast or mined fairly quickly resulting in fewer overall orphans.
