my cognos reporting team have an issue, few reports take 7 mins to fetch report of 3k records, which references 10+ tables, and sufficient indexes in place. At the earlier stage of the project my ex-collegues have given a wrong probmise to client that such reports can be rendered within one minute which doesn't seem to be realistic. I need to negotiate client with some facts. I need some direction. By the way, possible tuning efforts were already done. Only at this stage we were given 3k of test data and realizing the problem. Clients are reasonable, just that I need to explain them with some standards and fact. Any directions? Thanks in advance
