Hi, I'm sorry to hear you're not getting the performance you expected from the Jaspersoft server. We have many users and use cases of successful large deployments with high performance so I'm confident we can, with some more details, identify the root cause for the issues you outline. RedShift is indeed a very fast BigData DWH, however, there are a few places performance issues can initiate, from the queries optimization, cache settings and Jasperserver configuration. Can you answer the following questions: Are you experiencing the issues in reports or when using Ad-Hoc data explorationAre you trying to list 1,000,000 rows or are you aggregating them?Is the issue happen when rendering a large table of data, chars or both?Can you share the configuration of your AWS Ad-Hoc (Go to Manage -> Server Setting -> Ad-Hoc settings)Ad Hoc Dataset Row LimitAd Hoc Query Timeout (seconds)Optimize Queries for Domain-based ReportsOptimize Queries for JDBC-based ReportsWith this information we can begin estimating where the issue may be located and focus our next steps. Thanks, Assaf
