Speed issues with List View queries in 7.2 (on site)

I've installed 7.2.0 Pro on site in a test environment - and set up a large number or accounts (100k+), contacts (200k+). The system is working fine but standard list views are taking a long time: accounts approx 10 seconds, contacts approx 28 seconds.

It's definitely the database query as the timescales are the same pulling a listview via the API.

I've captured the MySQL slow query and running the query directly produces similar times.

The database and web server are separate and configurations are similar to the servers running our live v6 installation with similar numbers of records. I

If we add a filter to the listviews, then the times come down - it appears that the query is pulling all non-deleted records, before sequentially processing each for the related record joins, and then subsequently applying the 1-20 row limit. Ideally, only the base module table should be processed, with the sort order being handled by indexes before the limit is applied and then, joined against the other tables.

I've tried experimenting with adding indexes but with no luck. Any thoughts on what to try?

It's quite difficult to post readable snippets using this site, so I'll attached readable images - but the full query follows if you want to try it locally.
