Unofficial Benchmarks
For getting a rough idea about CPU speed, I have a physical table about German ZIP codes, and long distance telephone prefixes, filled with nearly 20,000 records in six fields, summing up to 2.25 MiB of data. From the original source in the internet, there were a lot of duplicate records. Birgitta Hauser came up with an quick and dirty idea how to eliminate these dupes.[1]
Since the SQL proved to be running really slow, I came up to use it as a benchmark. Of course, it's not 100 fair, because of different OS releases and accompanying improvements in SQL handling. But it gives a rough idea.
The SQL was run from a source PF member as standard batch job (default parameters) on idling machines (no additional work).
| Machine | Proc. Feat. | OS | Runtime (ca.) | Comments |
|---|---|---|---|---|
| 9401-150 | 2270 | V4R5 | Canceled after 6 hrs | Is currently running again until the very end. |
| 9406-S20 | 2161 | V4R4 | About 13.5 hrs | |
| 9406-800 | 7408 | V5R2 | About 2 hrs | |
| 8203-E4A | 5587 | V7R2 | 1-2 Minutes | LPAR with two CPU cores assigned. |
