Benchmarking Service
Benchmarking Services help development teams identify and correct performance issues before they become a market-facing problem. Working closely with customers' development teams, MontaVista consultants create a set of tailored performance benchmarks, then perform system tests to measure its performance against them.

Gain System Insight Through Benchmarking Services
In a Benchmarking Services engagement, MontaVista expert consultants work in close conjunction with customers' development teams to tailor a set of measurements for benchmarking and performance. Using customers' specific hardware configuration, MontaVista measures and evaluates the system resource configuration. It can also do comparisons against hardware configured to an equivalent "footprint" of a competitor's system.
Fast and Accurate Results Optimize Development Schedule
While timeframes vary depending on specifics of the benchmarking to be done, most engagements are delivered within a 4-5 week schedule. The engagement can include Performance Testing to create a baseline, Performance Benchmarking to have clear understanding of performance factors and measurements, and a written report. MontaVista can then help development teams identify follow on work to update code, or provide training on how to best code for performance.
