Summary :
This SAP Note addresses performance issues with client operations in R3trans, specifically copying, exporting, deleting, and importing, which sometimes exceed usual runtimes. Detailed benchmarks for throughput such as 120 MB/hour for client copying and 80 MB/hour for client deletion are provided. Key performance bottlenecks identified include inefficient handling of cluster and transparent tables, main memory limitations, and database-specific problems like inadequate indexing or lock issues. Solutions offered range from pre-deletion of large clusters to optimize operations to direct manipulation of physical cluster tables to avoid unnecessary logical processing and improve speed significantly in releases before 3.1G.
