请帮我解决这个问题。 我正在使用OpenERP 6.0
目前我遇到了性能问题。 问题是，当我转到供应商或客户付款时，我选择 partner_id 让询问系统自动检索合作伙伴的未结帐单我选择付款（实际上有 150发票 ，这是未完成的。）
所以，当我选择它的时候，系统正在花费 2分30秒来检索这150张发票，这对我来说花了很多时间。

实际上我已经检查了使它变慢的代码在哪里。它是附加的，将值插入项目行。
default['value']['line_ids'].append(rs)
if rs['type'] == 'cr':
default['value']['line_cr_ids'].append(rs)
else:
default['value']['line_dr_ids'].append(rs)
您是否有任何想法可以通过修改代码解决此性能问题（使其更快）？
谢谢
