The 25 transactions is not a hard limit (its a guideline), its what was tested. We recommend that if you are running more the 25 scripts to use more then one NAS, but if you go over that and you server is not overly taxed it should work with no problem, but again this is not supported, and was not tested. Also this was tested with Oracle backend which is slowest. MSSQL backend can probably handle more.
