STAC Report: HPE Overclocked Servers under STAC-N1

Lowest publicly reported max latencies for an Ethernet-based solution

16 February 2017

STAC has released audited STAC-N1™ results from overclocked HPE Trade & Match servers using a Solarflare network stack.  The STAC Report is available here.

STAC-N1 measures the performance of a host network stack (server, OS, drivers, host adapter) using a market data style workload. This benchmark was performed on a pair of HPE ProLiant XL170r Gen9 Servers with one Intel E5-1680 v3 (Haswell) processor per server, boosted by custom HPE tools to enable over-clocking for high-frequency trading operations. In the servers were Solarflare SFN 8522-PLUS Adapters and RHEL 6.6.

Compared to all other public STAC-N1 reports of Ethernet-based SUTs, this SUT demonstrated:

  • The lowest max latency at both the base rate (100K messages per second ) and the highest rate tested (1 million messages per second ).  Max at 1 million mps was 18 microseconds vs the previous best 51 microseconds (SUT ID SFC141110).
  • The lowest mean latency at both the base rate and the highest rate tested.

The report analyzes latencies and other metrics in detail. Premium subscribers have access to a CSV file with results for several message sizes beyond the standard size used for the report, a detailed STAC Configuration Disclosure, and a complete sosreport for the system.
