Performance Improvement over V1.5 is shown in the following table. All tests were executed on a 2 CPU virtual machine on Windows 7 32 bit, running SQL 2012 SSIS. Multi Threading was turned off, as there were insufficient columns being hashed to make it worthwhile.
| Test Details | V1.5 Performance | V1.5.1 Performance |
| 512Mb input file, 50 Columns, 3 Hashs of 50 Columns | 143.437s | 98.219s |
| 118Mb input file, 1102 Columns, 3 Hashs of 2, 6, and the rest Columns | 80.781s | 37.844s |
| 592Mb input file, 1102 Columns, 3 Hashs of 2, 6, and the rest Columns | 361.578s | 178.969s |
Please note that your results may vary depending on what else is in your SSIS package. In some cases there is no performance improvement. I'll post more details shortly.
