Just a quick note for those interested in trying a new set of accounting reports. We've published account_jasper_report module for OpenERP v6, which provides Journal, Trial Balance, General Ledger, and Invoice List reports. Until now, we've been using account_financial_report which had some modifications over standard and older reports, but unfortunately performance was very poor for companies with lots of account moves.

The new module is very fast and can create a General Ledger report with 58.000 move lines and 1.300 pages in just 1 minute and 30 seconds. (We had to wait several hours with older reports!).

Note that you will need latest version of jasper_reports module (download here).
