'My trades' takes a long time to load

'My trades' screen takes a long time to load on the production SB instance, despite the fact that the server is on a paid tier:

There are perhaps 20 entries in the Trading History table - this shouldn't matter, but we have previously considered whether there might be something about the way cc node and/or the app work that means that it takes longer to load as trading history accumulates. For investigation.
