Domain Mapping Plugin Causing Increased Page Load Times

Over the last year or so we've seen increasing page load times due to the domain mapping plugin on multiple multisite installations ...I've attached two screenshots from the PS3 plugin profiler showing the load times .... It looks like the increase load times might be related to the extended functionality that has been added to the plugin ...... would it be able for you to audit the domain mapping plugin to fix the increasing load times that have crept in over the last year or so? We've been using it for at least 6 or so years and wanted to reach out before abandoning it for other lighter solutions that exist .....Also noticing others have the same unresolved issue in other posts ... Any feedback appreciated.
