1. If the CPU cores were enough, you can add more primary segments in terms of your RAM, e.g. 8 primary segments per node. 2. Run gpcehckperf on both source and target environments to confirm if they have similar performance. 3. gp_vmem_protect_limit=49152, statement_mem=1GB could be a starting point. 4. Make sure you have run analyzedb after the migration. 5. If you still see performance issues after above changes, please share the execution plan of the slow queries for further investigation. -- This is an automated message from the Apache Git Service.
