Benchmark Testing Overview

STAC recently conducted baseline and scaling STAC-M3 Benchmarks on a comprehensive stack that involved Pure Storage’s FlashBlade//S500¹. The stack featured KX’s kdb+ 4.0 DBMS, utilizing NFS version 3 to access an impressive 266TiB of total usable data across a single FlashBlade//S500 chassis (10x FlashBlades with two 24TB flash modules per blade). The kdb+ software was distributed across eight Dell PowerEdge R740xd servers, each equipped with two Intel Xeon Platinum 8260 CPUs and 256GiB of memory.

The STAC-M3 Benchmark suite is an industry standard for tick-analytics benchmarks, specifically designed for database software/hardware stacks managing large time series of market data. The results from both the baseline (Antuco) and scaling (Kanaga) suites demonstrate Pure Storage’s commitment to delivering exceptional performance.

This is the first solution Pure Storage has submitted for a STAC-M3 audit. Many participants tune their infrastructure stack and operating system extensively to get the best benchmarks possible. In contrast, Pure Storage chose to have the benchmark harness run with a baseline FlashBlade//S500, a common server and network architecture, and minimal configuration tuning to demonstrate that our customers can achieve maximum performance and simplicity when choosing Pure Storage as their time-series or tick-by-tick market data platform.

STAC-M3 and Pure Storage Audit Results

Faster Performance

Pure Storage’s solution involving kdb+ 4.0, Compatibility Rev I of the kdb+ STAC Pack, and eight database servers accessing a Pure Storage® FlashBlade//S500 via NFSv3 showcased remarkable speed gains versus a solution involving the same number of database servers, three network attached flash storage nodes, and Compatibility Rev H of the STAC Pack²:

  • 13 of 17 STAC-M3 Antuco mean-response time benchmarks witnessed improvements, including a 7x speedup in the 10-user theoretical P&L (STAC-M3.β1.10T.THEOPL.TIME).
  • 17 of 24 STAC-M3 Kanaga mean-response time benchmarks exhibited enhancements, such as a 1.3x-1.5x speedup in 50-user 12-day VWAB (STAC-M3.β1.50T.YR{1,2,3,4,5}VWAB-12D-HO.TIME).

Additionally, when compared to a cloud-based solution³, Pure Storage FlashBlade//S500 outperformed in 9 of 17 Antuco benchmarks and 12 of 24 Kanaga benchmarks, showcasing significant speed advantages.


These results validate the FlashBlade//S500 series’ performance for financial sector tick data and time series-driven workloads. The platform enables firms to run complex queries across data sets of any scale with maximum throughput and minimum latency.

As workloads increased in volume and thread count, Pure Storage FlashBlade//S500 demonstrated the ability to handle highly parallel workloads efficiently. The architecture allowed for seamless scalability, crucial for the demanding requirements of quant and high-frequency trading.

Jack Gidding, CEO of STAC, said: “We are pleased to welcome Pure Storage to the ranks of technology providers who submit solutions for independent testing against the customer-developed STAC Benchmark standards. Financial firms on the STAC Benchmark Council designed STAC-M3 to test a representative range of business use cases, and the need for fast and efficient time-series analysis has never been higher.”

STAC-M3 Antuco results were obtained with the entire data set centralized in a single directory, showcasing the efficiency that firms can gain by eliminating the necessity to distribute data across multiple, specific directories for optimal performance. This approach underscores the streamlined and effective data management facilitated by Pure Storage’s solution.
