Kx Systems kdb+ 2.7 on an IBM x3850 X5 with IBM System Storage DS352

Specs: STAC-M3 Benchmarks (Antuco Suite)

Stack under test:

- Kx Systems Kdb+ 2.7
- Red Hat Enterprise Linux 5.5 with ext3
- Intel Xeon X7560, eight core, 2.27 GHz
- IBM System x3850 with 512 GB RAM
- IBM System Storage DS3524 with multiple SAS disks / RAID 5

This stack is the same as that tested in an earlier report, but the benchmark suite in this report is broader, including compute-intensive benchamrks in addition to I/O-intensive benchmarks.

The code that produced the STAC-M3.ß1.1T.NBBO benchmark results in this report actually implemented STAC-M3.ß1.1T.NBBO-Q (see STAC-M3 Antuco specifications for descriptions of the operations). NBBO-Q involves processing and saving more data as well as more computation. It is valid to claim superior performance if NBBO-Q elapsed time is less than NBBO elapsed time. It is not valid to claim superior performance if NBBO elapsed time is less than NBBO-Q elapsed time; the relative performance is not determined in this case.

The STAC-M3 Benchmark suite is the industry standard for testing solutions that enable high-speed analytics on time series data, such as tick-by-tick market data (aka "tick database" stacks).
