Hello, the current o2m displaying the number "m" or related records in list view also has a performance issue I think: it seems it makes 'm' requests to name_get to the server to when counting the 'm' it will display (while it is useless). For instance in the base_external_referentials modules we had to drop the feature of displaying how many external mapping has each mapped model because it was too slow, making hundreds of extra requests. I hope the new system doesn't has this issue; sorry, so far I can't remember if that was happening under the GTK or web client or both. On Thu, Jan 7, 2010 at 4:18 AM, ppr (axelor)
