Kx Systems, a provider of fast databases and time-series analysis software, has worked closely with Intel to run a series of performance tests on Intel's new Xeon 5500 ("Nehalem") chipset and has confirmed major improvements in speed.

Kx and Intel have a long-standing relationship, with each firm benefiting from the other's expertise in multi-core processing. Kx's in-memory and on-disk database has been tested to run more than twice as fast on the Xeon 5500 in specific tests compared to the previous generation of processors. The benchmarking used market models on databases containing hundreds of millions of records and included floating point and integer calculations.
