Comment 2 for bug 1194132

I have reproduced this behavior on the customer's database and will be investigating it soon, but there is no immediate fix, as you can guess. The number of queries stems from the high level OpenERP model, which can of course lead to many suboptimal SQL queries when everything resolves at the low level. Adding a cache is a dangerous workaround (every cache comes with tricky invalidation issues), but there may be other solutions to reduce the number of queries here.

Thanks,
