> Defect Tracker #24593: Cases 5004 and 5835 have shown significant performance issues with resolving.  While much of the performance impact was addressed with the 5.5 resolving refactor there is still a large performance hit for resolving that seems largely dependent upon metadata cache.  We should investigate additional strategies (for example unified cache or writing more entries per index file read) as a way to increase performance.
