I think the first thing you should do is enable the debugging template and see what is taking longer compared to Adobe.
You can do this by going to http://localhost:8888/lucee/admin/web.cfm?action=debugging.settings
Enable whatever you need (db etc)
Then go to http://local.int.distrokid.com:8080/lucee/admin/web.cfm?action=debugging.templates and create a debugging template. Check to see what is taking a long time there.
Secondly, see if you can do the requests directly to lucee, for example https://localhost:8888
If those are fast then you can figure out what is going on with IIS/Apache
